Reverse SIP Calculator with Inflation – Calculate Your SIP to Reach a Fixed Goal
Planning for a financial goal but unsure how much to invest monthly? A Reverse SIP Calculator with Inflation helps you determine the exact monthly SIP amount needed to reach a future goal, adjusting for inflation over time. Whether you’re saving for a child’s education, retirement, or a dream purchase, this tool simplifies complex investment planning.
What Is a Reverse SIP Calculator?
Unlike a traditional SIP calculator, which tells you how much your regular investment will grow over time, a Reverse SIP Calculator tells you how much you need to invest each month to reach a specific goal amount. It works backward from your target and considers your investment duration, expected returns (CAGR), and inflation rate to provide an accurate monthly SIP amount.
Why Include Inflation in SIP Planning?
Inflation erodes the value of money over time. A goal of ₹10 lakh today may be converted to ₹20 lakh in 15 years to match the same purchasing power. Including inflation in your calculations ensures you are investing enough to meet your future goal in real terms, not just nominal terms.
Example of Inflation Impact
If your goal is ₹10,00,000 in today’s value and inflation is 6% annually for 15 years, your actual goal becomes ₹24,00,000. This calculator adjusts for that and helps you plan your SIP accordingly.
How to Use the Reverse SIP Calculator
- Enter your goal amount – the amount you want in today’s terms.
- Input the expected CAGR – the average annual return percentage you expect from your investment (usually 10–15% for equity mutual funds).
- Select your investment duration in years.
- Provide the inflation rate – the annual rate at which the cost of living is expected to rise.
- The calculator will display the required monthly SIP adjusted for inflation and the expected total gain over the period.

Key Terms to Know
1. CAGR (Compound Annual Growth Rate)
This is the average annual return expected on your investments. It assumes your returns are reinvested each year and gives a smoothed-out growth rate over time.
2. Inflation
The rate at which the general price level of goods and services rises. Factoring this in is essential to ensure that your future goal retains real-world value.
3. Future Value (FV)
The inflated value of your goal, considering inflation over the chosen period.
4. SIP (Systematic Investment Plan)
A method of investing fixed amounts at regular intervals in mutual funds. It builds investment discipline and takes advantage of rupee cost averaging.
Practical Examples
Example 1: Saving for Higher Education
You want to save ₹15 lakhs for your child’s education in 12 years. Assuming a 12% Compound Annual Growth Rate (CAGR) and 6% inflation, the calculator will adjust the goal to ₹30+ lakh and indicate the Systematic Investment Plan (SIP) required to reach that future amount.
Example 2: Buying a House
Planning to buy a home worth ₹50 lakhs in 10 years? The calculator factors in inflation (say 7%) and shows that you might need over ₹98 lakhs, along with the monthly SIP required to reach there.
Advantages of Using a Reverse SIP Calculator
- Goal-Oriented Planning: It focuses on the end amount you need, not just generic returns.
- Realistic Estimates: Adjusting for inflation, it gives a practical monthly SIP target.
- Time-Saving: No complex math or spreadsheets required.
- Flexible: Change inputs to instantly compare scenarios and outcomes.
- Investment Discipline: Knowing your SIP goal helps you stick to the plan better.
FAQs – Frequently Asked Questions
1. How is this different from a normal SIP calculator?
This one works in reverse—it tells you how much you should invest monthly to reach a specific goal, factoring in inflation. A normal SIP calculator shows what your monthly SIP will grow into, assuming a fixed amount.
2. Is including inflation necessary?
Absolutely. Without accounting for inflation, your future purchasing power may fall short, leaving you underfunded when you need it most.
3. Can I use this for short-term goals?
Yes, but SIPs are generally more effective for medium to long-term goals (5+ years). For shorter durations, consider debt funds or fixed-income instruments.
4. What inflation rate should I use?
Use 5%–7% for general household goals in India. For education or healthcare-related goals, you may consider a higher inflation rate of 8%–10% in the country.
5. Is this calculator suitable for tax planning?
No, this calculator focuses on goal-based planning. For tax efficiency, consult with a financial advisor or use a tax-saving calculator.
Limitations to Keep in Mind
- Assumes constant CAGR and inflation over the investment period
- Does not account for taxation, fund fees, or market volatility
- Projections are estimates, not guarantees
- Only considers monthly SIPs, not lump sum investments
Tips for Effective Goal-Based Investing
- Start early to maximize the benefit of compounding
- Review your goals and SIP amount annually
- Increase SIP with income growth to stay ahead of inflation
- Diversify your mutual fund portfolio for balanced risk
