Light RFC: What It Means for a Disability Claim

A light RFC generally describes work with more lifting and more time on your feet than sedentary work. The exact limits still matter: the label does not mean every light job is available to every person SSA places in that category.

RFC is SSA’s administrative assessment based on the full record. A diagnosis or one medical opinion does not automatically determine the result.

What light work requires

Light work involves lifting no more than 20 pounds at a time and frequent lifting or carrying of objects weighing up to 10 pounds. A full or wide range of light work generally requires a good deal of walking or standing. SSA rulings describe the usual benchmark as about 6 hours of standing or walking during an 8-hour day, along with the other requirements of light work.

The light occupational base is broader than the sedentary base, but many unskilled light jobs require standing or walking for much of the day. Some jobs are classified as light because of pushing or pulling controls even when a person sits much of the time. The job’s actual strength and movement demands matter, not just its title.

Light work and the Grid Rules

Table 2 combines a light RFC with age, education, and past work. Some rules at age 55 or older can direct Disabled when education and work experience also meet the rule. Other profiles direct Not disabled. Age 55 alone, or a light RFC alone, does not determine the result.

Review the light Grid Rules (Table 2)

When standing or walking is limited

If you cannot stand or walk for the usual light-work duration, SSA should consider the specific remaining abilities and the combined effect of all supported restrictions. The result is not automatically sedentary work: a function-by-function assessment may fall between the standard categories or include other limits. SSA may use the Grid Rules as a framework and may need vocational evidence to determine how many jobs remain.

Explain how long you can stand or walk at one time and across the day, whether you need a device or another person, how often you need to rest, and whether you can lift and carry frequently.

Practical evidence to organize

Keep treatment records and describe limits in concrete terms. A medical-source opinion can be more useful when it states the supported lifting, carrying, standing, walking, and break limits and explains the medical findings behind them. SSA makes the RFC finding and evaluates opinions for supportability and consistency with the record; a form or letter does not automatically control the decision.
