50th percentile rents: how exception payment standards work

Last updated June 20, 2026

Payment standards vs. Fair Market Rent covers the normal range: a PHA sets its payment standard somewhere between 90% and 110% of the area's Fair Market Rent. That band covers the overwhelming majority of jurisdictions. But HUD also publishes a second figure for every FMR area — the 50th percentile rent — and in markets where the standard band genuinely isn't enough, it's the basis for going higher.

What the 50th percentile rent actually is

Fair Market Rent is, by design, set near the 40th percentile of gross rents for standard-quality units in an area — the idea being that a voucher holder should be able to find a unit at or below that rent without being limited to the very cheapest end of the market. The 50th percentile rent is exactly what it sounds like: the rent level at the midpoint of that same distribution. It's always higher than FMR for the same area and bedroom size, because by definition more units rent above the 40th percentile than below it.

HUD publishes 50th percentile figures annually, by county, alongside (but separately from) the standard FMR tables.

Where this becomes an "exception payment standard"

A PHA whose payment standard — even set at the maximum normal 110% of FMR — still isn't enough for voucher holders to compete for units in their jurisdiction can request HUD approval for an exception payment standard, set with reference to the area's 50th percentile rent rather than FMR. This is HUD's release valve for tight, high-cost markets: rather than every voucher holder in an expensive submarket being priced out, the PHA can document the problem and get approval to pay more.

This isn't automatic, and it isn't universal — a PHA has to request it, justify it with local rent data, and get HUD sign-off. But where it's in place, it changes the ceiling materially.

What the gap looks like in practice — two Georgia counties

Because the 50th percentile is always above FMR, the gap between the two gives you a sense of how much room an exception payment standard could add in a given area. Two examples from Georgia's FY2026 data:

In both cases the gap is a fairly consistent percentage across bedroom sizes — roughly 8% in Albany, roughly 10% in the Atlanta-metro counties. That consistency is typical: the 50th-vs-40th-percentile spread tends to track the overall shape of an area's rent distribution more than any one bedroom size. The Atlanta-metro gap being wider is also typical — higher-cost, more competitive metros tend to show a bigger spread between the 40th and 50th percentiles than smaller markets, which is part of why exception payment standards get requested more often in exactly these kinds of submarkets.

Why this matters for underwriting

If you're evaluating a property in (or near) a metro where you suspect rents have outpaced the standard FMR-based payment standard, two things are worth checking before you assume a voucher tenancy is capped at the "headline" FMR number:

1. Ask the local PHA directly whether they have an HUD-approved exception payment standard in place, and if so, what it's set at. This is a PHA-specific policy, not something derivable from FMR data alone — two PHAs covering overlapping or adjacent areas can have different answers.
2. Use the 50th percentile figure as a rough ceiling estimate, not a guarantee. Even where an exception payment standard exists, it's typically set with reference to the 50th percentile rather than automatically equal to it — confirm the actual number rather than assuming the full gap applies.

The practical upshot: in a market where you're seeing voucher-program rents that look high relative to the published FMR, an exception payment standard tied to the 50th percentile rent is often the explanation — and it's worth confirming directly with the PHA rather than writing off the numbers as an anomaly.

For the other half of this — how a tenant's own contribution is calculated against whichever payment standard applies — the 30% rule walks through the Total Tenant Payment formula from the renter's side.
