# How long does it take from SSDI application to first payment?

The wait combines the SSA's decision time with the statutory 5-month waiting period.

**Direct answer:** From SSDI application to first cash payment usually takes 8–12 months if approved at the initial level, longer if appeals are needed — and cash benefits do not begin until the sixth full month after the established onset date, per the statutory 5-month waiting period.

## Decision time

Most initial decisions take 6–8 months. Compassionate Allowance flags reduce this.

## The 5-month waiting period

By statute, SSDI cash benefits begin the sixth full month after the established onset date. Back pay may still accrue for months after that.

## Medicare gap

Medicare eligibility begins 24 months after SSDI entitlement — a two-year insurance gap after approval.
