2026 VA Disability Back Pay Estimator
Estimate the retroactive compensation the VA may owe you based on your effective date and correct rating. Back pay runs from your effective date, often the day you first filed or your Intent to File, so a corrected date or rating can mean months, sometimes years, of compensation the VA owes you in a single lump sum.
Dates & Ratings
Back pay lives and dies on one date. Under 38 C.F.R. §3.400 the VA pays from the later of the date it received your claim or the date entitlement arose, and an Intent to File under §3.155 can lock that date in up to one year early. Pull the effective date straight off your decision letter, not from memory, and enter each rating period exactly as the VA wrote it. Guess here and the estimate means nothing.

Important: This Is an Estimate
This calculator uses 2026 rates (effective December 1, 2025). Actual back pay depends on rate changes over the period, exact effective date determination, deductions, and other factors. Rates change annually with COLA adjustments. For a precise calculation, consult with an accredited representative.
The Rating Math Behind Your Back Pay
Your back pay is built from your combined rating and how the VA calculates compensation from it. The more you understand that math, the better you protect every retroactive dollar tied to your effective date. These are the VA's own briefings on how it works.
