Start with Gross Pay

Gross pay is what you earn before deductions. For hourly workers, that usually means regular hours times your hourly rate, plus overtime hours times your overtime rate.

Example: 40 hours at $20/hr is $800. Six overtime hours at $30/hr is $180. Your gross pay estimate is $980.

Then Estimate Deductions

Deductions are where simple paycheck math gets messy. Taxes, insurance, retirement contributions, garnishments, and other deductions can all reduce take-home pay.

For planning, many workers use a percentage estimate. It will not be perfect, but it gives you a useful range.

Watch Overtime and Multiple Jobs

Overtime can change your gross pay quickly, and multiple jobs can make the picture harder to track. Keep each job separate when rates, schedules, and deductions are different.

If you combine everything into one note, you may lose the details needed to compare your estimate against your paycheck.

Use Estimates the Right Way

A paycheck estimate is not tax advice and should not replace payroll records. It is a planning tool. The goal is to know whether your paycheck looks reasonable and spot big surprises early.

Shift Log+ helps by updating the estimate as you log shifts, instead of waiting until the end of the pay period.
