Free Gross Up Calculator

A gross up calculator converts a desired net payment into the gross pay needed before taxes. Enter the take-home amount and withholding rates to estimate gross pay, tax withheld, and the gross-up amount.

Use it for bonuses, caregiver stipends, relocation allowances, corrected payroll checks, and other payments where the take-home amount matters.

Gross-up inputs

Start with the net amount you want the worker to receive, then enter the withholding percentages that apply to the payment.

Formula

Gross pay needed = target net payment / (1 - total withholding rate). Gross-up amount = gross pay needed - target net payment.

Gross-up calculator FAQ

What does grossing up a payment mean?

Grossing up means increasing a payment so the recipient gets a specific net amount after taxes or withholding are taken out.

How do I calculate gross up from net pay?

Divide the target net payment by 1 minus the total withholding rate. For example, $1,000 net with 34.65% withholding needs about $1,530.22 gross pay.

Should FICA be included in a gross-up calculation?

Include FICA when the payment is wages subject to Social Security and Medicare taxes. Exclude it only when your payroll or tax advisor confirms it does not apply.

Can household employers gross up caregiver pay?

Yes, but household employers should still track gross wages, withholding, and overtime rules. The net amount is not a substitute for payroll records.

Is this gross-up calculator tax advice?

No. It is a planning estimate. Use official payroll software, current tax tables, or a payroll professional for final withholding and filing decisions.

Payroll planning note

Gross-up estimates are useful for planning, but payroll filings still need official gross wages, withholding, employer taxes, and any overtime calculations that apply to the worker.
