What does this calculator do?
Use this overtime calculator to estimate how many overtime hours you built up in a month and what rough payout value that extra work could have. This is especially useful for employees who want to monitor hours, compare workloads or understand the financial value of extra work better.
Formula
Hour difference = actual hours − target hours\nOvertime = positive hour difference\nOvertime value = overtime × hourly wage\nValue incl. bonus = overtime value × (1 + bonus)
Example
Example: With 160 target hours, 172 actual hours, an hourly wage of €20 and a 25% overtime bonus, the calculator shows 12 overtime hours. Their basic value is €240, and the estimated payout increases further when the bonus is included.
