Introduction

ROI measures gain relative to cost: (Final Value - Initial Cost) / Initial Cost. It is intuitive for one-time investments—marketing campaigns, home renovations, or equipment purchases.

Return on Investment

ROI measures gain relative to cost: (Final Value - Initial Cost) / Initial Cost. It is intuitive for one-time investments—marketing campaigns, home renovations, or equipment purchases.

Annualized ROI

When holding periods differ, raw ROI is misleading. Annualized ROI converts total return into an equivalent yearly rate so you can compare a three-year flip against a ten-year rental.

ROI Limitations

ROI ignores time value of money unless annualized, and it does not capture risk or cash flow timing. For multi-year irregular flows, prefer IRR or Finance Calculator.

Examples

  • Stock trade: buy at $5,000, sell at $6,200 for 24% ROI.
  • Business equipment: include install costs and salvage value in cost.
  • Real estate: factor closing costs, not just purchase price.

How It Works

  1. Enter your amounts, rates, and term in the form. Use the same units shown in the labels (dollars, years, percent).
  2. Click Calculate to run the ROI Calculator engine. Invalid or empty required fields show a clear error message.
  3. Review the summary cards for the key outputs. Expand schedules or tables when available for period-by-period detail.
  4. Copy, print, or share your scenario link. Reset the form anytime to start a fresh comparison.

Formula

Future Value with compounding: FV = P(1 + r/n)^(nt). For periodic deposits, each contribution grows from its deposit date at the same periodic rate.
