Nischa's Personal Spending Philosophy

Reflecting on Career Transition and Personal Fulfillment

Ostrich Effect

This is a cognitive bias where people avoid looking at negative financial information, such as bank statements or bills, due to the fear of how it makes them feel. This avoidance can keep individuals stuck in disorganized financial situations.

Hedonic Treadmill

This concept describes the tendency for people to return to a relatively stable level of happiness despite major positive or negative events or life changes. In the context of spending, it means constantly buying new things for spikes of happiness that are not long-lasting or fulfilling.

Lifestyle Inflation

This occurs when an individual's spending increases at the same pace as their income. What might seem like necessary upgrades or luxuries become new necessities, preventing the gap between income and spending from widening and hindering wealth building.

Opportunity Cost

This refers to the value of the next best alternative that must be forgone when making a choice. Every dollar or pound spent on one thing means one less available for something else, highlighting the trade-offs in financial decisions.

Index Fund

An index fund is a type of mutual fund or exchange-traded fund (ETF) that holds a diversified portfolio of stocks or bonds designed to track the performance of a specific market index. By investing in an index fund like the S&P 500, you are investing in a small piece of many companies, providing diversification.

Target Date Retirement Fund

This is an investment fund that automatically rebalances its asset allocation over time, becoming more conservative as the investor approaches a specific retirement year. It starts with higher-risk investments and gradually shifts to lower-risk ones to protect capital as retirement nears.

65-20-15 Rule

This is a money management framework for allocating your net income (take-home pay after taxes). It suggests dedicating 65% to fundamental living expenses, 20% to fun spending, and 15% to future savings, investments, and extra debt payments.

?
What is the 'ostrich effect' in personal finance?

The 'ostrich effect' is a cognitive bias where people avoid looking at negative financial information, like bank statements or bills, due to fear of how it makes them feel. This avoidance can lead to disorganized finances and keep individuals stuck.

?
What are the first steps to take control of your finances?

The first steps involve building a peace of mind fund (one month's core expenses), paying off high-interest debt, building an emergency buffer (3-6 months' core expenses), and then starting to invest.

?
Should I use credit cards?

Credit cards are beneficial if used correctly, primarily for points, rewards, or bonuses, but only if you pay them off in full every single month. If you carry a balance, the interest charges outweigh the benefits.

?
Why is saving alone not enough for retirement?

With rising cost of living and inflation, saving money in a bank account means its value is eaten away quicker. Investing is necessary for money to grow sufficiently to cover retirement costs.

?
What are the best ways to invest for beginners?

For beginners, it's recommended to keep investing simple and long-term, focusing on index funds (like the S&P 500) and target date retirement funds, which offer diversification and automatic rebalancing.

?
How can I increase my income?

The easiest ways to increase income are asking for a pay rise by building a strong case of your value and responsibilities, or by switching jobs/companies, as research shows this often leads to significant pay jumps.

?
Is buying a house a good investment?

While historically seen as wealth building, buying a house is not always the best financial choice. Renting can be cheaper, and if you invest the difference, you might build wealth faster than through property appreciation, especially considering opportunity cost.

?
What is opportunity cost?

Opportunity cost is the value of the next best alternative that is not taken when a decision is made. Every dollar or pound spent on one item means that money cannot be used for something else, representing a trade-off.

?
How should I allocate my investments?

When deciding on allocation, consider both potential returns and your behavioral response to market fluctuations. Invest in something that encourages you to buy and hold, rather than reacting emotionally to market drops or surges.

?
What is the 65-20-15 money rule?

The 65-20-15 rule is a framework for allocating your net income: 65% for fundamental living expenses, 20% for fun spending, and 15% for future savings, investments, and extra debt payments.

?
Should I buy or lease a car?

It's generally recommended to buy a car that is three to five years old to avoid significant depreciation. Leasing is an option for wealthy individuals who don't mind the depreciation hit and want a new car every few years, but it's not the best financial choice for wealth building.

?
How can I track my spending and saving?

Many bank accounts offer categorized spending within their apps, providing a ballpark figure of where your money goes. The key is to ensure you are saving a minimum of 10% of your salary, rather than meticulously tracking every transaction.

?
How should couples discuss and manage money?

Couples should have open conversations about money beliefs, values, and financial goals. It's recommended to have a 'team fund' for joint expenses (proportionate to income) and individual 'me funds' for personal spending to maintain autonomy and prevent arguments.

?
What is passive income and how can I get it?

Passive income is money earned without actively working or investing time in it, although it often requires significant upfront effort. The easiest and most accessible way for most people to generate passive income is through long-term investing.

?
How important is my credit score?

Your credit score is very important as it impacts your ability to secure loans, mortgages, or even car financing, and determines the interest rates you'll pay. It's crucial to pay off outstanding debts on time and in full, and you can check your score for free online.

1. Build a Peace of Mind Fund

Calculate one month of your core living expenses (mortgage, rent, utilities, minimum debt payments, car payments) from your last 30 days of bank statements and save that amount. This fund provides psychological security for unexpected life curveballs like a broken boiler or car issues.

2. Prioritize High-Interest Debt Repayment

List all your debts by interest rate from highest to lowest. After making minimum payments on all debts, throw any extra savings into paying off the debt with the highest interest rate first, especially anything above 8%. This stops financial bleeding and is more effective than earning low interest on savings.

3. Establish an Emergency Buffer

Save three months of core living expenses if single with predictable income, or six months if head of household with a mortgage or unpredictable income. This buffer provides crucial breathing room and emotional well-being in case of job loss or health scares.

4. Complete Financial Foundations Before Investing

Ensure your peace of mind fund, high-interest debt repayment, and emergency buffer are fully established before starting to invest. This prevents being forced to sell investments at a loss during market downturns to cover unexpected expenses.

5. Start Investing Early and Consistently

Begin investing small, recurring amounts as early and often as possible to harness the power of compounding growth over time. This is a crucial lever for wealth building that many miss by delaying.

6. Use the 65-20-15 Rule for Income Allocation

Allocate your net income: 65% for core living expenses (fundamental), 20% for fun spending, and 15% for your future self (savings, investments, extra debt payments). This framework helps benchmark spending categories and build wealth.

7. Prioritize Income Growth Over Investing Small Sums

If you have a small lump sum that took a long time to save and your income is limited, focus on increasing your income first rather than investing that small amount. A wider ‘income river’ fills ’life milestone buckets’ faster.

8. Proactively Seek a Pay Rise

Build a strong case for a pay rise by detailing your accomplishments, increased responsibilities, and market rates for similar roles. Present this evidence to your manager or HR, aligning your contributions with company objectives.

9. Consider Switching Jobs to Increase Income

Research suggests that switching companies can lead to significantly larger pay jumps (e.g., 20-30%) compared to staying in one organization. If a pay rise is not feasible, explore new job opportunities to boost your income.

10. Continuously Invest in Yourself

Prioritize ongoing self-investment to increase your skills, knowledge, and value. This directly impacts your income potential and has a compounding effect on all other financial investments.

11. Maximize Employer-Sponsored Retirement Match

Inquire with your HR department about your employer’s retirement account and contribute at least enough to receive the full company match. This provides tax benefits and essentially free money, which should not be left on the table.

12. Utilize Individual Tax-Advantaged Accounts

Invest in your own individual tax-advantaged accounts (e.g., ISA in the UK, Roth IRA in the US) to allow your money to grow and be withdrawn tax-free. Maximize annual contributions to these accounts due to their significant tax benefits.

13. Keep Investing Simple and Long-Term

For long-term wealth building, invest in simple, diversified options like index funds (e.g., S&P 500) and target date retirement funds. These funds offer diversification and automatically rebalance to become more conservative as you approach retirement.

14. Avoid Emotional Trading

Do not let fear or greed dictate your investment decisions by frequently buying and selling based on market fluctuations. A ‘buy and hold’ strategy, like that of ‘dead people’ or those who forget their investments, often leads to better long-term returns.

15. Understand Opportunity Cost of Spending

Recognize that every spending decision has an opportunity cost, meaning the value of the next best alternative you forgo. Consider what you could gain by investing money instead of spending it immediately, balancing present enjoyment with future potential.

16. Counteract Lifestyle Inflation

As your income grows, be mindful of lifestyle inflation, where spending increases at the same pace. Aim to widen the gap between your income and spending, allowing yourself treats but not letting luxuries become perceived necessities.

17. Balance Present Enjoyment with Future Security

Allocate a percentage of your income for fun and enjoyable activities or luxuries, but ensure this spending does not compromise your long-term financial security or future goals. Spend without guilt when your future self is already looked after.

18. Avoid Over-Saving Cash

Only save cash for your peace of mind fund, emergency buffer, and short-term goals (within five years like a house or car deposit). Beyond these, avoid keeping excess money in a savings account, as inflation will erode its value.

19. Invest the Difference if Renting is Cheaper

If renting is financially cheaper than buying a home in your area (considering mortgage, interest, stamp duty, property tax, repairs, maintenance, insurance), invest the money saved from the rental difference. Automate this investment to create a ‘forced mechanism of saving’ similar to a mortgage.

20. Buy Used Cars to Avoid Overspending

Avoid buying new cars, as they are a major source of overspending due to rapid depreciation and emotional purchasing. Opt for a car that is three to five years old, as it has already depreciated significantly at someone else’s expense.

21. Use Credit Cards Strategically

Utilize credit cards for points, rewards, and bonuses only if you can pay off the full balance every single month. If you cannot afford to pay for an item outright in cash, avoid using a credit card for it, as companies profit from missed payments and high interest.

22. Monitor and Improve Your Credit Score

Understand that your credit score significantly impacts major purchases like cars or mortgages. Regularly check your credit rating for free online, ensure all details are correct, and consistently pay off outstanding debts and credit cards in full and on time.

23. Negotiate Debt Interest Rates

If you have high-interest debt, contact the company to negotiate a lower interest rate. Present a clear plan for how you intend to pay off the debt over a specific period (e.g., 12-18 months) to increase your chances of success.

24. Maintain Separate and Joint Finances in Relationships

Avoid fully merging finances with a partner. Instead, create a ’team fund’ for joint expenses (proportionate to income) and individual ‘me funds’ for personal spending. This balances unity with autonomy and protects individual financial access.

25. Ask Partner About Money Values Early

To understand a partner’s money beliefs, ask hypothetical questions like how they would spend a sudden windfall (e.g., $10,000). This reveals their underlying values regarding money and helps assess financial compatibility.

26. Discuss Money Upbringing with Partner

Engage in conversations with your partner about where their beliefs about money originated (e.g., childhood experiences, parental influence). This fosters empathy and compassion, leading to a better understanding of each other’s financial habits.

27. Leverage Expertise for Side Income

Identify your unique expertise gained from your career or life experiences and explore ways to turn it into a scalable side business, such as selling digital products or offering coaching. Ask friends what advice they seek from you to discover your niche.

28. Investing is the Easiest Passive Income

For most people, the most accessible and truly passive way to generate income is through long-term investing in diversified assets like the S&P 500. Other ‘passive’ income streams often require significant upfront time or energy.

29. Limit Speculative Investments

For highly volatile assets like crypto, allocate only a small, inconsequential percentage (e.g., less than 2%) of your overall portfolio. Invest an amount you are comfortable losing, especially after establishing core financial foundations.

30. Focus on Minimum 10% Savings Rate

For those who dislike detailed budgeting, simplify financial tracking by ensuring you save a minimum of 10% of your salary. This core habit is more important than meticulously tracking every transaction, providing freedom for other spending.

31. Combat Marketing to Save on Groceries

Be aware of supermarket marketing tactics designed to encourage overspending. Use a shopping list and compare prices at different supermarkets to ensure you’re getting the best value on necessities.

32. Question Technology Upgrades

Apply the law of diminishing returns to technology purchases like new iPhones or iPads. The initial happiness from a new device is significant, but subsequent upgrades offer less additional satisfaction, so consider if each upgrade is truly necessary.

33. Read “The Richest Man in Babylon” for Financial Basics

If you find financial topics boring, read “The Richest Man in Babylon” as it simplifies fundamental saving and spending principles through an engaging narrative, making financial literacy more accessible.

34. Cultivate Obsession for Your Desired Path

To pursue a new career or life path, dedicate more time and energy to it than to listening to external critics. Shift from being merely ‘interested’ to ‘obsessed,’ as obsession provides the courage and drive to make difficult decisions.

35. Amplify Your Inner Voice Over External Noise

When facing external criticism or doubt about a life-changing decision, write down the ’external noise’ and, separately, what your ‘inner voice’ is telling you. Regularly read and repeat your inner voice’s message to make it louder and counteract self-doubt.

36. Embrace Reversible Decisions Quickly

For major life decisions that are reversible (Type 1 decisions), act quickly and take the leap. The biggest regret is often not living the life you could have, and if you can always go back, the risk of trying is minimal compared to the regret of ‘what if.’

If you give someone else the power to feed you, you're also giving them the power to starve you.

Avoiding it, thinking that, oh, it's just going to disappear if I don't look at it. It's that thing that keeps you stuck.

Saving three to six months of your living expenses does more for your emotional well-being than earning over 200k.

You cannot save your way to retirement.

The wrong choice isn't choosing the wrong path. It's just not knowing that you even had a choice in this whole thing.

Nischa Shah

Dead people outperformed the living when it came to investment returns. Because they didn't touch their investment account.

The biggest risk isn't quitting my job. The biggest risk is letting this once-in-a-lifetime opportunity pass me by and never knowing where that path could have taken me.

Nischa Shah

Only you have to grow old with the memories of what could have, should have, would have been. And live with the what if.

4 Steps to Take Control of Your Finances

Nischa Shah
  1. Build a peace of mind fund: Calculate one month of your core living expenses from your last 30 days of bank statements and save that exact amount.
  2. Cut the financial bleeding: List all your debt by interest rate from highest to lowest. Make minimum payments across everything first, then throw any extra savings into the highest interest rate debt, and move down the list.
  3. Build your emergency buffer: Save three times your core monthly living expenses if you are single with predictable income, or six times if you are head of household with a mortgage or unpredictable income.
  4. Start investing: Once steps 1-3 are complete, begin investing through your employer-sponsored retirement account (if available) and your own individual tax-advantaged account.

How to Ask for a Pay Rise

Nischa Shah
  1. Build a strong case: Document all your accomplishments, responsibilities taken on, and instances where you went above and beyond your job description.
  2. Research market value: Investigate what similar roles with your level of seniority are paid in your industry and city.
  3. Consult HR: If available, speak to your HR department to understand if your current salary aligns with the average for your role and department.
  4. Find an ally: Discuss salary with a trusted colleague or mentor to gain insights and encourage financial transparency.
  5. Present your case: Frame your request by highlighting the value you've brought, aligning it with company objectives, and expressing your desire to stay, then discuss a fair salary adjustment.

Nischa Shah
  1. Initiate conversations early: Ask questions like 'If you won $10,000, how would you spend it?' to understand their money values, and 'Where did your beliefs about money come from?' to foster empathy.
  2. Establish shared goals: Discuss your two-year, five-year, and ten-year financial goals as a couple.
  3. Create a 'team fund': Contribute proportionately to your incomes for joint expenses such as mortgage, rent, bills, and council tax.
  4. Maintain 'me funds': Each partner should have an individual account for personal spending, allowing for autonomy and independent financial habits without judgment.
