Estimate Your Mutual Fund Growth
Enter your lumpsum amount, monthly SIP, expected return, and investment horizon to estimate your future corpus.
Why use a mutual fund investment return calculator?
A mutual fund calculator helps you estimate how your money can grow through a combination of compounding, monthly SIP investments, and long-term discipline. Instead of guessing your future corpus, you can run realistic scenarios and make better financial decisions.
This tool is useful for retirement planning, children’s education goals, wealth creation, and financial independence. By changing inputs like expected return, time horizon, and SIP step-up, you can quickly see how small changes today impact your final result.
How this calculator works
1) Lumpsum growth
Your initial one-time investment is compounded monthly for the entire duration. This means your gains begin generating gains, which is the core of long-term investing.
2) SIP growth
Monthly investments are added each month and then compounded for the remaining period. Earlier SIP installments get more time to grow than later installments.
3) Step-up SIP
If you increase your SIP every year (for example by 5%–10%), your total corpus can rise significantly over long horizons. This calculator includes an annual step-up field to model salary growth and increasing savings capacity.
4) Expense ratio adjustment
Mutual funds charge management fees (expense ratio). The calculator subtracts this from your expected return to estimate a more practical net growth rate.
Input guide: what to enter
- Initial Investment: Existing amount you invest right now.
- Monthly Investment (SIP): Amount invested every month.
- Expected Annual Return: Long-term annual return assumption before expense ratio.
- Investment Period: Number of years you plan to stay invested.
- Annual SIP Step-Up: Percentage increase in SIP every year.
- Expense Ratio Impact: Approximate annual cost deducted by the fund.
- Inflation Rate: Used to estimate purchasing power in today’s money.
Example scenario
Suppose you invest ₹50,000 upfront and ₹5,000 monthly for 15 years. If your expected return is 12%, expense ratio is 1%, and SIP step-up is 5%, you could build a substantially larger corpus than a flat SIP strategy. The exact value depends on market performance, but this estimate helps you set a realistic target.
Lumpsum vs SIP: which is better?
It is not always an either/or decision. Many investors combine both:
- Invest a lumpsum when cash is available (bonus, inheritance, asset sale).
- Continue SIP monthly for consistency and rupee-cost averaging.
- Increase SIP annually to stay ahead of inflation and lifestyle inflation.
Important limitations to remember
- Mutual fund returns are market-linked and not guaranteed.
- Actual returns may be volatile, especially in the short term.
- Taxation, exit loads, and fund category risks are not included here.

Best practices for realistic projections
Use conservative return assumptions
For long-term planning, conservative assumptions reduce disappointment and improve decision quality.
Review your plan every year
Revisit your SIP amount, goals, and asset allocation as income and life priorities change.
Stay invested for longer horizons
Time in the market is often more powerful than timing the market. Long duration generally smooths out volatility.
