Equity Return Calculator

Bought 100 shares at 10 (1,000), sold at 12 (1,200), received 40 dividends = 240 total return on 1,000 = 24%. Dividends often overlooked but material. Over long periods, dividends contribute 30-50% of total equity returns.

A worked example

Try the defaults: buy price per share of 10, sell price per share of 12, number of shares of 100, total dividends received of 40. The tool returns 24.00%. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.

What moves the number most

The result responds to Buy Price per Share, Sell Price per Share, Number of Shares, and Total Dividends Received. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.

The formula behind this

Capital gain + dividends divided by cost. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.

Using this well

What this doesn't capture

Steady-rate math ignores real-world volatility. Actual returns are lumpy; sequence-of-returns risk matters most in drawdown; fees and taxes drag on compound growth; and behaviour changes in drawdowns can reduce outcomes below the projection. The number represents one scenario rather than a forecast.

Common scenarios

This calculator applies across many equity holding types. Investors use it to compare performance of individual stock positions held over months or years, to isolate the combined effect of capital appreciation and income yield, and to test how much difference dividend reinvestment or additional share purchases would have made. Analysts also use it to backtest historical returns on documented purchases and sales.

Another realistic example

Suppose you bought 250 shares at a price of 40 per share (10,000 total invested). Over three years, the share price rose to 52. You also received 750 in cumulative dividends. Your capital gain is 3,000 (250 shares × 12 per-share gain). Adding dividends, your total return is 3,750 on an initial outlay of 10,000, which equals 37.5%. The calculator shows this at a glance.

What the result does and does not show

This tool estimates the return from entry price to exit price, plus all income collected in between. It does not account for timing of dividend payments, tax liability on gains or income, brokerage fees or commissions, reinvestment of dividends into additional shares, or inflation's effect on purchasing power. It also does not model volatility, drawdowns, or the timing sequence of returns—all factors that influence real experience.

Educational illustration

This calculator is for educational illustration of how capital gains and dividends combine to form total return. Results are estimates based on your inputs and do not forecast future performance or account for individual circumstances.
