Payroll example

At $20 per hour, 3 hours 45 minutes produces gross base pay of $75.00 before taxes, deductions, overtime, or other adjustments. The calculation uses the unrounded value: 3.7500 × $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, =3+45/60 returns 3.7500. Format the result as a number rather than a clock time.
