PIP back pay calculator
PIP is paid from the date you started your claim. Pick the rates you were awarded, or expect, and your claim start date to see roughly how much back pay you could get.
Your estimated back pay
| Tax year | Days | Amount |

This is an estimate only. Only the DWP can decide your award and how much you are paid. If you have already had some PIP for this time, it will be taken off.
How PIP back pay works
If you are awarded PIP, it is paid from the date you started your claim, so your first payment may include a back payment. After that, PIP is usually paid every 4 weeks into your bank account.
PIP rates usually go up each April. This calculator uses the rate that applied on each day, so a claim that runs over April is worked out at both the old and new rates.
If you challenge a decision
Many decisions are changed when people challenge them. If your rate changes after a challenge, you can use this calculator again with the new rates. Read how to challenge a PIP decision.
