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.

Frequently Asked Questions

A gross-up is an additional amount of money added by an employer to a payment to cover the income taxes the employee will owe on that payment.

It adds your federal, FICA, and state rates into a single total rate, then divides your desired net pay by one minus that total rate over 100. The result is the gross amount needed so that, after those taxes, you are left with your target take-home.

The FICA rate defaults to 7.65%, though you can change it. It is combined with the federal and state rates you enter to form the total withholding rate used in the gross-up.

The tool subtracts your desired net pay from the grossed-up amount. The difference is the total tax withheld, which it also splits into separate federal, FICA, and state portions.

The gross-up divides by one minus the total rate over 100. If the combined rate reached or passed 100%, that divisor would be zero or negative, so the tool requires the total rate to fall between 0 and 100.
