Estimate your retroactive disability pay — the lump sum the VA owes you from your effective date forward. The effective date is usually the single biggest factor.
Estimate only. Suggested rates are the current 2026 figures (effective Dec 1, 2025) for a veteran with no dependents; back-pay periods before Dec 2025 used lower rates, and dependents raise yours — use the amount on your VA award letter for accuracy. The VA makes the official calculation.
An earlier effective date can mean thousands more in back pay. VetAid checks whether yours should be earlier — and builds the argument if it should.

The formula is simple: your monthly rate × the number of months from your effective date to the award. The VA starts paying the first day of the month after your effective date.
The effective date is usually the date you filed your claim, or the date entitlement arose if that's later. Two important exceptions:
Not filed yet? An Intent to File (VA Form 21-0966) locks in today's date while you build the claim — step 2 of the claim readiness checklist.

Monthly rate × months from your effective date to the award. Payment starts the first of the month after the effective date.
Usually the date you filed, or when entitlement arose. Filing within a year of separation can push it back to the day after discharge.
Yes, if you were 30%+ with dependents during the back-pay period — use your exact rate for accuracy.
Usually a lump sum within a few weeks of the decision, separate from monthly payments.
