After-tax investment returns for gig workers: a practical guide

Published February 17, 2026 · 2 min read

After-tax investment returns explained for gig workers, with a worked example, a checklist and the mistakes to avoid.

Why this matters for gig workers

Gig workers are usually treated as self-employed, so tax is their responsibility on every payout.

Worked example

Here is the calculation with sample figures. Change any number in the After-Tax Return Calculator to run your own.

After-tax investment returns: how it works

A 7% return is not 7% if part of it is taxed. Multiplying the return by 1 minus the tax rate shows what you keep.

Over many years the gap between pre-tax and after-tax compounding becomes large.

A second example with larger figures

Scaling the inputs up shows how the result moves. Percentages stay the same, so the tax grows in proportion to the amount it is applied to.

Using the calculator step by step

1. Open the After-Tax Return Calculator.
2. Enter your own figures on each numbered line.
3. Set the rate to the one that applies to you. Defaults are examples, not advice.
4. Read the result and the formula below it.

Key terms
