VA Disability Back Pay Estimator
Estimate the retroactive benefits you may be owed when your disability rating changes with a new effective date.
How VA Back Pay Is Calculated
No partial months. If your Intent to File (ITF) or claim was submitted mid-month, your official effective date is the first day of the following month (38 CFR § 3.400; § 3.155). VA never prorates a partial month.
Paid in arrears. VA pays for a month on the first day of the next month. April's compensation arrives May 1.
Where back pay ends. Your lump sum covers every full month from your effective date through the month before your decision month. Your first regular monthly payment is the one covering the decision month itself — it is not part of back pay.
Example: ITF submitted March 10, 2026 → effective date April 1, 2026. Claim granted September 20, 2026 → back pay covers April through August (5 months). The September payment, deposited October 1, begins your regular monthly compensation. At 70% (veteran alone, 2026 rate): 5 × $1,808.45 = $9,042.25.
Disclaimer: This calculator provides a rough estimate only. It applies current 2026 compensation rates uniformly across the entire period and does not account for historical rate changes, dependency changes over time, or combined-rating adjustments. Your actual back pay may differ.

Effective-date disputes are one of the most overlooked sources of additional backpay. An accredited claims agent can review whether you may be entitled to an earlier date — and additional retro pay.
