Bonus Calculator

How it is calculated

The bonus has two parts that are added together. percent bonus = salary × bonus_pct ÷ 100, then total bonus = percent bonus + flat_bonus. The tool also divides the total by 12 as a monthly equivalent, total bonus ÷ 12, which only makes sense if the salary is a yearly figure and the bonus is paid once a year. The result is the gross amount before income tax and social contributions, which are not applied here and differ by country. The percentage works on the salary you type, so enter base pay, not base plus overtime, unless your plan says otherwise. Both parts may be zero. A flat bonus field must be filled in (type 0 if none), and negative values give no result. The tool does not check plan caps or payout multipliers.

Common mistakes

• Entering a monthly salary and reading the monthly equivalent as a pay rise. The percentage applies to whatever salary you type, and the monthly figure divides the total by 12, so use the yearly salary.
• Typing the bonus percentage as a fraction (0.10). The field is in percent, so 10.
• Treating the total as take-home pay. It is before tax, and payroll often withholds a higher rate on a one-off payment.
• Leaving the flat bonus empty when there is none. The field needs 0, otherwise no result appears.
• Assuming the target is what you will receive. Plans often scale the payout up or down with company or personal performance, which this tool does not model.
