Time & Pay Calculators

Timesheets, deadlines and overtime all hide small conversions that cause real arguments: 1:30 is 1.5 hours and not 1.3, ten working days is two weeks plus any holidays, and overtime depends entirely on the threshold and multiplier that apply to you. These calculators do the conversions exactly and show their working, so the figure on the invoice or the deadline in the proposal matches what everyone expects.

Rules about working time and overtime vary by country and contract. The calculators apply the numbers you enter; the explainers tell you which numbers to check.

• Hours to Decimal ConverterTurn hours and minutes into decimal hours for timesheets and invoices, and back
• Overtime Pay CalculatorOvertime pay from hours over a threshold, your base rate and a multiplier, plus the total for the period
• Working Days CalculatorCount working days between two dates, or add working days to a date, skipping weekends and your own holidays
