How to use the Investment Growth Calculator

Three modes, one tool. Pick the one that matches your question.

  1. 01

    Pick a mode

    SIP calculates how a fixed monthly investment grows. Lump Sum shows how a one-time investment compounds. Goal Planner works backwards: enter a target corpus and it tells you the monthly SIP required to get there.

  2. 02

    Enter your numbers

    For SIP: monthly amount, expected annual return, and years. For lump sum: the principal, rate, and years. The projection updates instantly, no button to click.

  3. 03

    Turn on inflation adjustment

    The default result shows nominal value, what the number will be. Enable inflation adjustment to see real value, what that money will actually buy. At 6% inflation, ₹1 Cr in 20 years is worth about ₹31 L in present-day money.

What people use it for

Planning a retirement corpus

Enter your target retirement amount and years to retirement. The Goal Planner shows the exact monthly SIP needed. Most people are surprised how achievable it is when started early.

Comparing SIP vs lump sum

Got a bonus or windfall? Run both modes with the same rate and years to see whether investing it all now or spreading it monthly gives a better outcome. (Lump sum usually wins at the same rate, but SIP reduces timing risk.)

Understanding the cost of waiting

Run the same SIP at 12% for 25 years, then for 20 years. The 5-year difference is often more than the total amount invested in those 5 years. That's compounding.

Checking if a return assumption is realistic

Nifty 50 index funds have averaged 12–14% over 20-year periods. Debt funds return 6–8%. Small-cap funds can hit 15–18% but with much higher volatility. Use realistic rates, not best-case ones.

Worked examples for each mode

SIP mode: ₹10,000 a month for 20 years at an assumed 12% grows to about ₹99.9 lakh, from ₹24 lakh invested. Each instalment is treated as invested at the start of the month.

Lump sum mode: ₹5,00,000 invested once for 20 years at 12%, compounded yearly, grows to about ₹48.2 lakh, nearly ten times the original.

Goal mode works backwards. To build ₹1 crore in 20 years at 12%, you'd need a monthly SIP of about ₹10,009. The inflation setting, 6% to start, then shows what that corpus is worth in present-day money: ₹1 crore in 20 years buys roughly what ₹31.2 lakh buys now.

Reading the results sensibly

  • The return is an assumption. Equity has historically returned more than bonds and deposits over long periods, but with large swings; a steady 12% every year doesn't happen in practice.
  • Lump sums are compounded yearly and SIPs monthly, so compare like with like when switching modes.
  • Fund costs and tax on gains aren't deducted, and both reduce the final figure.
  • Use the inflation-adjusted value when planning a goal such as retirement; the nominal figure always looks bigger than it will feel.

Frequently asked questions

Free, no account needed. All calculations run in your browser.
SIP (Systematic Investment Plan) means investing a fixed amount every month. Lump sum means investing everything at once. SIP reduces the risk of investing at a market peak. Lump sum earns more if the market goes up consistently, but timing matters more.
For equity mutual funds (Nifty 50 index): 11–13% is a reasonable long-term assumption. For debt funds: 6–8%. For PPF: 7.1% (current rate). Don't use 15–18% for planning; that's optimistic and leads to undersaving.
It shows what your maturity amount will be worth in today's purchasing power. If inflation runs at 6% and your investment grows to ₹1 Cr in 20 years, the real value is about ₹31 L. That's what ₹1 Cr will buy then compared to now.
No. Long-term capital gains on equity funds above ₹1 L/year are taxed at 12.5% (post-Budget 2024). Debt fund gains are taxed at your income slab. The actual post-tax return will be lower than what this calculator shows.
It uses the future value of annuity formula: SIP = FV × r / ((1+r)^n − 1) / (1+r), where r is the monthly rate and n is the number of months. This is the standard formula used by all SIP calculators.
