Payroll example

At $20 per hour, 8 hours 15 minutes produces gross base pay of $165.00 before taxes, deductions, overtime, or other adjustments. The calculation uses the unrounded value: 8.2500 × $20. This avoids the small difference that can result from multiplying a displayed two-decimal value.

Excel formula

If the whole hours are in A2 and minutes are in B2, use =A2+B2/60. For this example, =8+15/60 returns 8.2500. Format the result as a number rather than a clock time.
