The formulas
- Before the bonus: bonus = rate x income
- After the bonus: bonus = rate x (income - bonus), so bonus = rate x income / (1 + rate)
How it works
Bonus plans tied to profit define the base precisely: before or after the bonus itself, and sometimes after income tax. When the base is income after the bonus, the bonus appears on both sides of the equation, and solving it gives rate x income / (1 + rate).
Read the plan for caps, thresholds and the income measure used, which is often adjusted for items such as gains on sales. Recompute from the audited income figure and adjust the accrual when audit adjustments change income.

Common questions
What if the bonus is after income tax as well?
Then bonus = rate x (income - bonus - tax), and tax also depends on the bonus. Solve it with the tax rate in a spreadsheet.
Do audit adjustments change the bonus?
Yes, when the plan is formula based. An adjustment to income flows through to the bonus.
Is a discretionary bonus accrued?
When there is a present obligation, such as a past practice of paying, and the amount can be estimated.
