Absolute Return Calculator

Formula and valuation basis

Return (%) = (final value + included cash − initial outlay) / initial outlay × 100

Without separate distributions, included cash is explicitly excluded and the calculation is ordinary value change. The initial outlay is positive; final value and an enabled distribution amount are nonnegative. Gain or loss = final value + included cash − initial outlay.

Use total amounts in one currency and one consistent cost basis. If using cost-adjusted amounts, include entry costs in the initial outlay and exit costs in final net proceeds. No fee or tax is calculated automatically; do not deduct the same charge twice. This is a chosen cash-outlay convention, not a universal tax or fund-reporting formula.

Verified worked examples

Initial outlay 10,000, final value 12,000, and separately paid cash of 500: value change = 2,000, or 20%. Cash-inclusive gain = 12,000 + 500 − 10,000 = 2,500. Holding-period return = 2,500 / 10,000 × 100 = 25%. The model assumes no growth on the separate cash.

If the final value is 9,500 with 500 paid outside it, the selected-basis result is 0%, although the valuation alone fell 5%. A zero final value with 1,000 of separate cash from a 10,000 start produces a 90% loss; with no separate cash it is a 100% loss.

How to use this calculator

1. Choose a display market: USA/USD, UK/GBP, Canada/CAD, Australia/AUD or India/INR. This does not convert currencies.
2. Enter total initial outlay and final value as ungrouped decimals with a point.
3. Enable separate distributions only for cash outside the final value. The enabled field is required; zero is valid when explicitly entered.
4. Flag additional contributions or capital withdrawals. The result is withheld because timing-aware performance needs another model.
5. Read the percentage, gain or loss, included cash and value-change rate together. Clear values removes the scenario from memory.

Assumptions and supported limits

Initial outlay: 0.000000000001 to 10^30. Final value and enabled cash distributions: zero or that positive range. Maximum 12 fractional places and 64 input characters. A zero or negative initial outlay, negative valuations, grouped numbers, scientific notation, NaN and Infinity are rejected. Turning off distributions clears their amount rather than retaining a hidden stale value.

The engine uses 50 significant decimal digits with half-even rounding. Display precision does not alter the math. Tiny nonzero results stay visible; near-total losses are not shown as false complete losses. These are whole-period amounts with no dates, cash-flow timing, reinvestment, automatic inflation, tax, fee or FX adjustment.

Avoid interpreting a deposit as profit, mixing per-share prices with portfolio totals, or treating a positive result as proof of low risk or outperformance. Absolute return can be negative. Comparing different holding periods requires context; the related CAGR tool has its own endpoint and no-flow assumptions.
