Work backward from desired net pay to estimated required gross pay, taxes, and employer payroll cost.

Employers gross-up bonuses, equity payouts, and taxable reimbursements so workers receive an promised net amount. Without gross-up math, a $5,000 promised net might land as $3,400 after withholding.

Actual payroll systems vary—flat 22% federal supplemental versus aggregate method changes results. Use this calculator for planning, then validate with HR payroll previews.

Gross-up does not cover non-tax deductions like 401(k) loans or garnishments unless you model them explicitly.

How to use this tool

Enter the desired net, state, filing status, and any deductions. Use the required gross and employer cost as planning estimates.

Worked example

To deliver a $5,000 net payment, the required gross is higher because estimated withholding and payroll taxes are included.

When to use this

  • HR planning net bonuses for executives or relocation packages.
  • Employees verifying employer gross-up calculations on offer letters.
  • Estimating true cost of taxable fringe benefits.

Common mistakes

  • Using effective tax rate instead of marginal rate on supplemental wages.
  • Ignoring state and local taxes in high-tax jurisdictions.
  • Assuming gross-up covers Social Security cap nuances for high earners mid-year.

How it works

The calculator iteratively solves for gross pay that produces your requested net pay after estimated taxes and deductions.
