# What is residual functional capacity?

The RFC is expressed in terms of exertional level (sedentary, light, medium, heavy), plus specific nonexertional limits such as postural, manipulative, environmental, or mental restrictions.

**Direct answer:** Residual functional capacity (RFC) is the SSA's assessment of the most you can still do in a work setting despite your medical limits, as defined in POMS DI 24510 and 20 CFR 404.1545.

## Who determines RFC?
The disability examiner and medical consultant at the initial and reconsideration levels; the ALJ at the hearing level based on the entire record.

## What evidence supports RFC?
Objective medical findings, treating-source records and opinions, consultative exam reports, and your own reports of function.

## How does RFC affect the outcome?
RFC is compared to the demands of your past work at step four and to other work in the national economy at step five, together with age, education, and skills.
