Return on investment calculator

Compare what you invested with what you received. See your gain or loss, total ROI, and annualised return.

Your investment

All amounts are in Nepalese rupees (NPR).

Your return, explained

Enter your amounts and duration to see the return breakdown and an illustrated value chart.

How this tool works Method, sources & assumptions

Developed by Suraj Pokhrel. Calculations are estimates; the method and assumptions explain how to interpret them.

How to interpret ROI

ROI = (amount returned − amount invested) ÷ amount invested × 100. An investment of NPR 10,000 returning NPR 12,000 has a 20% total ROI. Over two years the simple annual return is 10%, while CAGR is approximately 9.54%. Include fees and taxes in your inputs if you want a net return. CAGR assumes no intermediate cash flows.

USEFUL ANSWERS

Read ROI without confusing it with annual growth

Use ROI to compare the ending amount with the starting amount. Use CAGR to express that change as an equivalent compound annual rate when there are no intermediate deposits or withdrawals.

Should “amount returned” contain my profit or my final balance?

Enter the full final amount, including the returned principal. Investing NPR 100,000 and finishing with NPR 120,000 means entering 120,000, not 20,000. The tool subtracts the initial amount to calculate the gain.

Why are ROI, simple annual return and CAGR different?

NPR 100,000 becoming NPR 120,000 in two years gives 20% total ROI. Dividing by two gives 10% simple annual return. CAGR is approximately 9.54%, the constant compounded annual rate that connects those two balances.

Can I use this ROI calculator for monthly SIP deposits?

Not as a cash-flow-aware performance measure. This calculator assumes a starting amount and an ending amount without intervening contributions. Use the investment calculator for a hypothetical recurring-contribution scenario; irregular actual cash flows need a dated cash-flow method such as XIRR.

Does the chart show actual investment performance?

No. It illustrates a constant-CAGR path between the entered amounts. It is neither observed price history nor a forecast. With a zero final amount, only the endpoints are shown because a total loss does not define a smooth compound path.
