The VA does not add disability ratings together with simple math. Instead, it uses a “whole person” approach: your highest rating is applied first, then each additional rating is applied only to the remaining percentage of efficiency. The final figure is rounded to the nearest 10%. Our live combined rating calculator walks through each step, can model a basic bilateral factor for paired disabilities, and estimates monthly pay with dependents, TDIU, and SMC options.

Rates effective December 1, 2025 (2026 compensation year), from VA.gov. Veteran alone (no dependents): 10% $180.42, 20% $356.66, 30% $552.47, 40% $795.84, 50% $1,132.90, 60% $1,435.02, 70% $1,808.45, 80% $2,102.15, 90% $2,362.30, 100% $3,938.58. With spouse only (examples): 30% $617.47, 50% $1,241.90, 70% $1,961.45, 100% $4,158.17. SMC-K add-on is $139.87. Use the pay chart for full dependent combinations, and always verify on VA.gov.

Yes — because of rounding and special programs. Multiple ratings can round to 100%, and veterans who cannot work due to service-connected disabilities may qualify for TDIU, which pays at the 100% rate even if the schedular rating is lower. Our TDIU eligibility checker and combined rating “what if” simulator help you explore those paths. Permanent and Total (P&T) status is a separate determination about whether disabilities are expected to improve.

Back pay (retroactive benefits) is compensation owed from your effective date up to the date the VA starts paying you regularly. The amount depends on your rating history, effective date rules, dependents, and any SMC. Use our live back pay calculator with the effective date tool to estimate that figure — then confirm with your award letter or a VSO.

Often yes. At 30% and above, a spouse, children, or dependent parent can increase schedular pay. SMC-K ($139.87) is an add-on; higher SMC levels can replace the schedular rate. Paired extremity disabilities may get a bilateral factor before combining. Our calculators model these options for education — always verify against VA.gov and your decision letter.

No. VA Disability Calc is an independent educational resource. Our calculators are for estimation only. Always verify your benefits with the VA or an accredited Veterans Service Officer (VSO).
