Investment Return Calculator – Total %

Quick answer

Return = (ending − starting + income) ÷ starting: 20,000 growing to 27,500 with 900 of dividends returns 42% total, 12.4% annualized.

How Does the Investment Return Calculator Work?

Total return = (final value − initial value + income) ÷ initial value × 100

A proper return number counts both growth and cash thrown off. The calculator takes your starting value, ending value, and any dividends or interest received, then computes the holding-period return. Example: 20,000 that becomes 27,500 while paying 900 of dividends returns (27,500 − 20,000 + 900) ÷ 20,000 = 42% over the period — miss the dividends and you understate by 4.5 points. Held over 3 years, that 42% compounds to (1.42)^(1/3) − 1 ≈ 12.4% annualized, the figure to compare against benchmarks. The same engine handles losses (ending at 16,400 is −13.5%) and partial sales: enter what was sold and what remains at market value. For portfolios with deposits mid-year, switch to money-weighted IRR so each contribution is timed correctly.

FAQs

How do I calculate total return on an investment?

Total return = (final − initial + income) ÷ initial × 100. From 20,000 to 27,500 with 900 dividends: (7,500 + 900) ÷ 20,000 = 42%.

Should dividends be included in the return?

Yes — they are part of what the investment paid you. Skipping the 900 in the example understates return by 4.5 percentage points (37.5% vs 42%).

What is 42% over 3 years per year?

Annualized = 1.42^(1/3) − 1 ≈ 12.4% per year, the number directly comparable to index benchmarks.

How do mid-period deposits change things?

They distort simple formulas: money added late did not experience the early gains. Use money-weighted IRR, which times each cash flow by its date.

What return should I compare against?

A broad market index for the same period and asset class — e.g. a 12.4% annualized equity return vs an index at 10% signals outperformance worth verifying after fees.
