Dreaming of becoming a crorepati? The 15-15-15 rule is a simple yet powerful way to build ₹1 crore over time. It’s not a get rich quick scheme but a disciplined approach that anyone with patience and consistency can follow.

What is the 15-15-15 Rule?
The 15-15-15 rule is a wealth building formula based on three key numbers:
- ₹15000: The amount you invest every month.
- 15%: The annual return you aim to earn on your investments.
- 15 years: The time period you stay invested.
By following this rule you can grow your money to ₹1 crore through the magic of compounding. Compounding means earning returns not just on your initial investment but also on the interest or profits you make over time. Think of it like a snowball rolling downhill it starts small but grows bigger as it picks up more snow.
How Does the 15-15-15 Rule Work?
Let’s understand the math behind the rule. If you invest ₹15000 every month for 15 years at a 15% annual return your money grows significantly due to compounding. Here’s a simple breakdown:
- Monthly investment: ₹15000
- Total invested in 15 years: ₹15000 × 12 months × 15 years = ₹2700000
- Expected return: 15% per year (compounded)
- Final value: Approximately ₹1 crore
The exact amount depends on the investment vehicle and market conditions but the 15-15-15 rule shows that disciplined investing can lead to massive wealth over time. For example mutual funds or stocks with a history of 12–15% average annual returns can help you achieve this goal.
Why the 15-15-15 Rule is Powerful
The 15-15-15 rule works because it combines three important factors:
- Regular investing: Putting in ₹15000 every month builds a habit of saving and investing.
- High returns: A 15% annual return is achievable through equity mutual funds or stocks which historically perform well over the long term.
- Longterm commitment: 15 years allows compounding to work its magic turning small monthly investments into a large corpus.
This rule is realistic for many middle class Indians. If ₹15000 a month seems high you can adjust the amount and time frame based on your income but the principle remains the same invest regularly aim for good returns and stay patient.
Steps to Follow the 15-15-15 Rule
Here’s how you can start using the 15-15-15 rule to build ₹1 crore:
1. Create a Budget
To invest ₹15000 monthly you need to free up this amount from your income. Make a budget to track your expenses and cut unnecessary spending. For example reduce eating out or cancel unused subscriptions. Saving even ₹500 a day (like skipping a coffee or cab ride) can add up to ₹15000 a month.
2. Choose the Right Investment
To achieve a 15% return focus on equity-based investments like:
- Mutual Funds: Invest in diversified equity mutual funds with a strong track record. Choose funds with a history of 12–15% annual returns.
- Stocks: If you understand the stock market invest in quality companies. However stocks are riskier and require research.
- Systematic Investment Plans (SIPs): Set up a monthly SIP in mutual funds to automate your ₹15000 investment.
Consult a financial advisor to pick funds that match your risk appetite and goals.
3. Start Early and Stay Consistent
The earlier you start the better. Even if you can’t invest ₹15000 right away begin with a smaller amount like ₹5000 and increase it as your income grows. Consistency is key don’t skip investments even during tough months.
4. Understand the Risks
A 15% return is not guaranteed. Equity investments can be volatile, and markets may go up or down. However, over 15 years, the ups and downs usually balance out, giving you good average returns. Stay calm during market dips and keep investing.
5. Monitor and Adjust
Review your investments every 6–12 months. If a fund is underperforming consider switching to a better one. Reinvest your profits to maximize compounding. Avoid withdrawing your money early as it disrupts the growth process.
Tips for Success
- Increase investments over time: As your salary grows increase your monthly investment to reach ₹1 crore faster.
- Avoid debt traps: High-interest loans or credit card debt can eat into your savings. Pay off debts before investing heavily.
- Stay disciplined: Treat your ₹15000 monthly investment like a fixed expense like rent or bills.
- Learn about investing: Read books or watch videos to understand mutual funds and compounding better. Knowledge builds confidence.
Common Mistakes to Avoid
- Chasing quick returns: Avoid risky schemes promising high returns in a short time. Stick to trusted investments.
- Timing the market: Don’t try to predict market ups and downs. Regular investing through SIPs averages out costs.
- Ignoring inflation: ₹1 crore may not have the same value in 15 years. Plan for additional savings if you want more purchasing power.
