About Gross-Up Paycheck & Bonus Calculator

The Gross-Up Paycheck Calculator computes the total gross compensation an employer must pay so that after all statutory tax withholdings, the employee receives the exact net cash target requested.

Formula & Mathematical Calculation

Total Tax Withholding Rate (%) = Federal Withholding % + FICA (7.65%) + State Tax Rate %

Gross-Up Pay Amount = Desired Net Payout / ( 1 - Total Tax Withholding Rate % / 100 )

Calculation Example

Desired Net Bonus = $5,000.00 (Total Tax Rate = 22% Federal + 7.65% FICA + 5% State = 34.65%): Required Gross Payment = $5,000 / (1 - 0.3465) = $7,651.09.
