What is the Investment Calculator?
See what regular monthly investing (SIP / DCA) can grow to at an expected annual return. Money decisions are easier when you can see the numbers. Our finance calculators use the same standard formulas banks and financial planners use — amortization, compound interest and present-value math — so you can compare options before you commit.

How to use the Investment Calculator
- Enter your monthly investment, your expected annual return, your years.
- Results update automatically as you type; you can also press Calculate.
- Read the output: future value, total invested, estimated gains.
- Use the 📊 chart to see the result visually, then copy or share it.
Formula and method
Worked example
With monthly investment = $500, expected annual return = 8 %, years = 20 years, the Investment Calculator returns future value: $294,510.21; total invested: $120,000.00; estimated gains: $174,510.21.
Tips for better results
- Compare at least two scenarios (for example, a 15- vs 30-year term) before deciding.
- Small rate differences compound: a 0.5% lower rate can save thousands over a long loan.
- Results are estimates; your lender’s fees, taxes and exact day-count rules may change the final figure.
