Short answer
Use gross wages for wage math, net pay for take-home planning, and deduction lines for explaining the difference between the two.
A paycheck calculator is only as good as the number you feed into it. The most common mistake is entering take-home pay into a field that expects gross pay.
Open Weekly Paycheck CalculatorThe fast way to diagnose it
Working rule: Net pay = gross pay - taxes - deductions + non-wage reimbursements, when applicable.
Realistic example: A stub may show $1,050 gross, $185 taxes, $70 deductions, and $40 reimbursement. The deposit is not just gross minus taxes; every line matters.
Key checks
- Find current gross wages.
- Separate taxes from deductions.
- Keep reimbursements outside normal wage income.
- Check whether the period is weekly, biweekly, semimonthly, or monthly.

Gross pay answers whether the hours and rate are right.
Net pay answers what reached the bank account.
