What is the ROI Calculator?

Calculate return on investment (ROI) and annualized return from your cost and final value. 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 ROI Calculator

  1. Enter your amount invested, your amount returned, your holding period.
  2. Results update automatically as you type; you can also press Calculate.
  3. Read the output: roi, annualized roi, net profit.
  4. Use the 📊 chart to see the result visually, then copy or share it.

Formula and method

ROI = (Final − Cost) ÷ Cost × 100 Annualized = (Final ÷ Cost)^(1/years) − 1

Worked example

With amount invested = $1,000, amount returned = $1,500, holding period = 2 years, the ROI Calculator returns roi: 50.00%; annualized roi: 22.47%; net profit: $500.00.

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.
