i A planning tool built on the Back Pay Act Full Summary. Enter what you know; the estimate updates live. Every figure is an approximation for orientation only.
This is an estimate, not a promise or legal advice. Real awards are computed individually by the agency and depend on facts only a final settlement from MSPB and/or counsel can confirm. Several inputs below are marked Pending because they are still with Joanna — the tool will not assume an answer for you. Do not build a financial plan on any number here.

1 Your federal pay

Pick your grade, step, and duty-station locality — the tool fills in your salary from the official 2025 GS scale. This is your rate at separation; raises during the gap are handled just below.

Your grade and step set here carry into every benefit calculator. Make sure they're right before you continue — the other calculators read them from this page.

Current (2026) salary

base × locality

Used by the benefit calculators — it sets your leave accrual rate and feeds your service credit. It doesn't change the numbers on this page.

2 The timeline

The initial decision is the hinge. Before it = back pay (offsets apply). After it = interim relief (a separate forward stream).

Set for the group — July 14, 2025.

3 Pay growth

Your corrected pay isn't frozen at your July 2025 salary. Add the within-grade step increases you'd have reached across the gap, plus any allowances you were owed.

4 What you earned elsewhere

Replacement earnings during the back-pay gap only. Do not include income you already had before the RIF — pre-existing moonlighting is carved out and never offsets.

$

5 What you already received

These were paid because of the separation. They come back out of the award in this order — not a penalty, just no double payment.

6 Interest

Back pay earns interest at the IRS § 6621 overpayment rate, compounded daily. The tool applies the real published rate for each quarter automatically — no assumption to enter.

7 Still with counsel

These questions are unresolved. Toggle them to see how the answer would move your estimate — but treat the result as hypothetical until Joanna confirms.

Concurrent federal pay raises a separate dual-compensation / reconciliation question. Flags the result; does not change the math.

8 Unemployment compensation

Benefits you collected during the gap. How they hit your money depends on your state — netted from your award, billed to you out of pocket, or protected. Pick your state to see.

9 Annual & Sick Leave

The annual and sick leave you'd have accrued across the gap — restored as hours on your record, not paid as cash.

10 TSP + Breakage

Your missed contributions, the agency automatic 1% and match, and breakage — plus the make-up choice that flows back into your award above.

11 Retirement Service Credit

Creditable time added to your record for the gap — feeds your high-3 and retirement eligibility.

12 FEHB & FEGLI Restoration

Health and life coverage reinstated, and how the five-year coverage clock is treated.

Then the normal withholdings come out before this reaches you — retirement, FICA/Medicare, health & life premiums, and income tax — and finally any administrative offset for other federal debts. Retirement and life are figured on gross before offset; tax and FICA on the adjusted figure after.

Interim relief — separate stream

Former federal salary, paid forward from the initial decision to final. Not clawed back. Not part of the back-pay math above.
