Prorated bonus calculator
Prorate a target bonus by the days someone was in post during the bonus year.
Prorate a target bonus by the days someone was in post during the bonus year.
Prorated bonus = full-year bonus × days in post ÷ days in the bonus year.
Someone in post for half the days receives half the bonus, if the plan prorates by days. Plans that use whole months, or that pay nothing below a minimum service, need the rule from the plan. This page only applies the day count you enter.
Full bonus £5,000. 183 days in post. 365-day year. 5,000 × 183 ÷ 365.
£2,506.85
365 days in post out of 365. The share is 100%.
£5,000
Use the same kind of day in both boxes. Calendar days in post over calendar days in the year is the usual pair. Working days over working days is also fine. Mixing them is not.
Days in post are the days from the bonus-year start, or from their start date if that is later, through their last day. The plan may say they forfeit the bonus if they leave before the payment date. This page does not apply that rule.
Enter months worked in the days box and 12 in the year box. Three months is then a quarter of the bonus.
