VA back pay calculator

Enter your effective date, the date payments began, your awarded rating, any prior rating if this was an increase, and your dependent status. The calculator counts payable months under 38 CFR §3.31 and applies the rate table in force for each month.

How this estimate works

Under 38 CFR §3.31, monetary benefits may not be paid for any period before the first day of the calendar month following the month in which the award became effective. If your effective date is October 15, the first payable month is November. The calculator adds 1 month to your effective date to find that starting point, then counts complete calendar months up to, but not including, the month payments began.

Each month is priced at the VA compensation rate table in force that month. Rates change on December 1 each year (the COLA effective date). For a back-pay period that spans a December 1 boundary, the calculator applies the old table through November and the new table from December onward. The difference is often small month to month but can add up over a multi-year span.

For rating increases, the calculator computes the difference between the new rate and the prior rate each month. Back pay on an increase equals only the additional amount VA should have paid, not the full new rate. Enter your prior rating in the "Prior rating" field to activate this mode. Leave it at "None / new award" for an initial grant.

What this calculator does not model

Several factors can affect the actual VA back-pay figure that this tool does not capture:

The result is an estimate. The actual VA computation, shown in your award letter, may differ for any of the reasons above.

Finding your effective date in the decision letter

Your decision letter (the rating decision, not the cover letter) states the effective date for each condition and for the combined rating. Look for a section titled "Effective Date" or a table that lists each diagnostic code, the assigned rating, and a date. That date is the one to enter here. For claims filed with an intent to file, the effective date is typically the intent date, not the full-application date.

If the effective date in the letter does not match your records, that discrepancy is reviewable. See what to do after a VA decision you disagree with for the right review lane.

Related tools and guides

The VA back pay guide explains how effective dates are set, how intent-to-file protects your start date, and how review decisions affect back pay. The pay rates section shows the full rate tables by year, so you can look up the exact monthly figure for any rating and dependent status. The combined-rating calculator verifies whether your combined rating is correct before you apply the rates.

If your rating was understated because of a missing bilateral factor or a missed condition, a corrected rating on review triggers back pay at the difference. Read what to do after a VA decision you disagree with to identify whether a Higher-Level Review or Supplemental Claim is the right step.
