How this calculator works
Signing bonus clawback clauses appear in most offer letters where the sign-on payment is meaningful — typically anything over about $10,000. They exist because companies want protection: if they pay a lump sum up front to convince you to join, they don’t want you walking out three months later. The mechanics vary, though, and small differences in wording lead to very different math.
Pro-rated vs. full (cliff) clawback
A pro-rated clawback means the amount you owe back decreases each month you stay. If your bonus is $30,000 and your clawback period is 12 months, leaving after 6 months means you owe back roughly $15,000 — the portion representing the time you didn’t serve.
A full (cliff) clawback is more punitive: you owe 100% of the bonus back if you leave any time before the end date, then $0 the moment you cross the finish line. Under this structure, leaving at month 11 of a 12-month period means owing back the entire $30,000 — even though you served 92% of the required time. Cliff clawbacks are common in banking, some consulting, and certain aggressive tech offers.
What the calculator assumes
- Linear pro-rating. The pro-rated calculation assumes a straight line: month N of an M-month period means owing back (M − N) / M of the bonus.
- Full month credit. We count full months elapsed as of your departure date, rounding down. Partial months don’t credit unless your offer letter says otherwise (some do; check yours).
- Gross amount owed. The amount shown is what the company will demand. You paid taxes on the gross when you received the bonus — recovering those taxes is a separate process (see FAQ).
What this doesn’t model
- Interest or penalties (rare, but some offer letters include them for late repayment).
- Tiered clawback structures (e.g., 100% for first 6 months, then linear to zero over the next 6). Model these by running two separate scenarios.
- The tax recovery mechanism. Repaying a gross bonus doesn’t automatically refund the taxes you paid — talk to a CPA about IRS Section 1341 or same-year payroll reversal.
- Any negotiated exceptions (constructive termination, layoff, role change). Read your offer letter for the exact triggers.
