Concurrent Calculator

This calculator helps estimate the combined backpay you might receive from both SSDI and SSI. By entering key dates and benefit amounts, you can see how much retroactive payment you’re eligible for, factoring in things like the SSDI waiting period, dependents, and legal representation.

Example Calculations

Rebecca

Rebecca, a 42-year-old administrative assistant, had been working full-time at a busy office when her health started to decline due to lupus. By mid-2022, the symptoms became too severe, forcing her to stop working entirely. After months of trying to manage her condition, she applied for SSDI on February 1, 2023. The SSA determined her disability onset date was August 1, 2022. After a long wait, Rebecca was finally approved for both SSDI and SSI on March 14, 2024.

With a monthly SSDI benefit of $1,200 and an SSI benefit of $200, she used the concurrent benefits calculator to determine her backpay. The results showed that Rebecca is eligible for $16,800 in SSDI backpay for 14 months and $2,600 in SSI backpay for 13 months, totaling $19,400. This backpay will help her cover medical bills and regain some financial stability while living with her condition.

Scott

Scott, a 38-year-old truck driver, spent years on the road before developing severe degenerative disc disease, which made it increasingly difficult to work. By early 2022, the pain and mobility issues forced him to leave his job. He applied for SSDI on October 1, 2022, after realizing he could no longer manage his symptoms while working. The SSA determined his disability onset date was April 1, 2022. After waiting over a year, Scott was finally approved for both SSDI and SSI on February 23, 2024.

With a monthly SSDI benefit of $1,400 and an SSI benefit of $250, Scott used the concurrent benefits calculator to estimate his backpay. The results show he’s eligible for $25,200 in SSDI backpay for 18 months and $4,250 in SSI backpay for 17 months, totaling $29,450. This backpay will allow Scott to catch up on overdue bills and ease the financial burden on his family as he navigates his new reality.
