Billable Hours Calculator
Enter start and end times, subtract a break, choose optional upward rounding, and estimate billable time plus a rate-based subtotal.
How the billable subtotal is calculated
The calculator finds one shift, subtracts the break, and rounds the remaining minutes up only when an increment is selected. It divides those billable minutes by 60 and multiplies the result by the hourly rate.
For example, 61 billable minutes at $120 per hour is a $122.00 subtotal with no rounding. With 15-minute rounding, it becomes 75 minutes and a $150.00 subtotal.
Calculation boundaries
This calculator subtracts the entered break, then rounds billable minutes up only when an increment is selected. Currency controls display formatting only; no exchange-rate conversion occurs. The subtotal is practical arithmetic, not an invoice, payroll, tax, accounting, employment-law, or recordkeeping determination.
