Gross-Up Calculator 2026 (US)

The take-home calculator answers "what do I keep from this gross?". A gross-up answers the inverse: "what gross do I need so that this net lands in the bank?". Employers use it for relocation bonuses, taxable reimbursements, and offers quoted as a net number.

This tool inverts the same 2026 engines as the take-home paycheck calculator — IRS Pub 15-T percentage method + employee FICA — with a binary search to the nearest cent.

Gross-up (one period)

find G such that take-home(G) = target net

take-home(G) = G − 401(k) − other pre-tax − federal withholding(G) − FICA(G)

Worked example

Single, biweekly, no 401(k), Step 2 unchecked, target net $1,500:

  • Required gross: $1,812.55
  • Federal withholding: ~$164
  • FICA: ~$139
  • Resulting take-home: $1,500

The $2,000 biweekly default from the take-home tool (net $1,651.15) round-trips: gross-up($1,651.15) recovers $2,000.

First look, not the final bill

Same scope cuts as the take-home engine: no W-4 Steps 3/4, no Additional Medicare Tax 0.9%, no Roth 401(k), no state or local tax. Educational estimate from IRS Pub 15-T (2026) and 26 U.S.C. § 3101; not tax advice.
