The question is not just which total is larger

A bigger bonus opportunity is not the same as a bigger salary. One offers more certainty month to month. The other may offer more upside, but only if it is actually paid.

Why after-tax comparison matters

Two structures with similar headline value can land differently in net pay once tax is applied. That is why the salary vs bonus calculator is useful when the fixed-versus-variable mix is the real issue.

What the calculator does not decide for you

It does not tell you how reliable the bonus is, whether the target is realistic, or whether the company tends to pay out consistently. That part still needs judgement.

Best next step

Use the calculator for the cash view, then save the scenario and note anything about certainty, timing, or culture that could change the real decision.

How to use PayPath here

Run the relevant calculator for your live numbers, review the methodology if the assumptions matter to your decision, and save the strongest scenarios in the workspace if you are comparing more than one option.
