Legacy Amount Projection Calculator

Work out legacy amount projection instantly with clear inputs, formula shown and shareable results.

About Legacy Amount Projection Calculator

The legacy is whatever remains after decades of withdrawals and growth. Stating it in today's purchasing power as well as nominal terms matters, because a large nominal figure decades out buys considerably less.

Formula

Legacy projection

Balance ← balance × (1 + return) - withdrawal each year; real value deflates the result at 5% inflation

Worked example

With the default values below, Legacy Amount Projection Calculator returns Projected Legacy Amount of $72,436,778.29. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or fees or charges into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
Figures are estimates for planning only. Prices, returns, inflation and personal circumstances all change. This is not financial or tax advice — speak to a qualified adviser before making decisions.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why show the real value?

Because a nominal legacy figure twenty-five years out overstates what it will actually buy by a wide margin.

Should a legacy target change withdrawals?

Yes. A meaningful legacy goal requires a lower withdrawal rate, which is a direct trade against current spending.
