It’s no surprise that new medical residents who matched at Barnes-Jewish Hospital for their post grad training assume St. Louis is going to be much less expensive than Boston, New York, or San Francisco because, obviously, it is.

Their stipend, which feels skimpy in those markets stretch much further in the Gateway City. The WashU GME Consortium publishes salary schedules that begin at $69,842 for a PGY-1 and reach $79,309 by PGY-4, figures that compare favorably to programs in cities where cost-of-living pressures are more severe.

This article calculates the monthly remainder after rent for one-bedroom apartment in the St. Louis metro area. Rent plus cost of living is what a disability insurance benefit would need to replace in the event of an unexpected illness of injury.

The U.S. Department of Housing and Urban Development publishes Fair Market Rent figures annually for metropolitan areas across the country. For the St. Louis, MO-IL HUD Metro FMR Area, the FY2025 Fair Market Rent for a one-bedroom unit was $984 per month. The WashU GME Consortium’s published salary schedule alongside that figure produces the following:

Estimate assumes single-filer federal withholding and Missouri state income tax. Actual take-home varies with voluntary deductions.

The HUD Fair Market Rent of $984 per month represents the 40th percentile of actual gross rents paid in the St. Louis metro area, the federally published threshold below which 40 percent of renter households paid in the most recent survey period. It is not an average of listed rents and not a landlord’s asking price for new leases. It is the closest approximation available from a federal source to what a resident entering the St. Louis rental market should expect to pay for a baseline one-bedroom unit.

What the WashU Stipend and St. Louis Rent Data Show About GSI Benefit Sizing

St. Louis is not an expensive city by national standards, and the $984 Fair Market Rent reflects that geography. A resident who trained in Boston or New York during medical school may have paid considerably more for a one-bedroom apartment, and that comparison can push the St. Louis number into a favorable light that distorts the enrollment decision. The relevant question on a GSI benefit form is not whether St. Louis is less expensive than New York. It is. The question is what $984 per month in housing costs means for the income a disability benefit must replace if a claim is filed during training.

The benefit amount selected at GSI enrollment is written into a non-cancellable individual disability insurance policy. That amount does not adjust automatically as income rises after residency. A WashU attending physician earning $300,000 annually who became disabled during or shortly after training, holding a GSI policy that pays $3,000 per month, would receive $3,000 per month, not a benefit calibrated to the income actually lost. That gap is addressed, in part, by the Future Increase Option rider, which allows the policyholder to increase monthly benefits at specified intervals without submitting to new medical underwriting.

After covering St. Louis’s HUD Fair Market Rent for a one-bedroom unit, a WashU PGY-1 resident has an estimated $3,536 per month remaining. That is the income figure a disability benefit must replace. It is the figure that belongs on the enrollment form.

The FIO rider must be purchased during training. A WashU resident who develops a qualifying health condition during residency and has not secured the FIO rider may find that future benefit increases require full medical underwriting that a changed health profile may no longer support. The 10 to 15 percent premium discount available to residents who enroll during training is also permanent for the life of the policy. It does not return after program completion, and it is not available on coverage purchased after training ends.

The physician who purchases a policy during residency and never returns to examine whether the benefit amount kept pace with income is the most common version of this problem.

“I wish that I had re-examined periodically to say, would this actually replace 60% of my income as intended, with a disability policy? Because income goes up as your patient panel goes up. But I never went back in the twelve years between underwriting the policy and finding I had a disability,” said Peter Crane, MD, a rural family physician in Idaho and host of the Doctors Making a Difference podcast, on the Income Protection Journal Podcast.

The FIO rider is the mechanism that addresses that gap, but only when it is attached during training, before the window closes.

The WashU resident guaranteed issue disability program window opens on the first day of residency training and closes when training ends. What closes is not only the chance to enroll without medical questions. It is the chance to enroll at all. A resident who understands the St. Louis cost structure before that window opens arrives at the enrollment decision with the number that belongs on the form, not an assumption about what the city costs relative to somewhere else.

Why the Benefit Sizing Decision Requires Local Data, Not Assumptions

After more than three decades advising physicians on disability insurance, one pattern holds: residents making GSI benefit decisions compare their situation to peers at other programs rather than to the actual cost structure of the city where they are training. The WashU resident’s financial situation in St. Louis is specific to this market. The $984 HUD Fair Market Rent is a St. Louis figure. The monthly remainder after that cost is the income floor a disability benefit needs to protect during training, not a national average and not a coastal comparison.

The guaranteed standard issue disability insurance programs available through approved residency programs set a benefit ceiling: a maximum monthly amount the program will issue without medical underwriting. Below that ceiling, the resident makes a choice. The table above provides the data that choice requires: the WashU GME Consortium’s published stipend by training year, the federal housing cost benchmark for the St. Louis metro area, and the post-rent monthly income that a disability benefit would need to cover if training were interrupted.

For WashU residents across all four training years, the monthly post-rent remainder ranges from $3,536 for a PGY-1 to $4,054 for a PGY-4. These figures do not account for food, transportation, or student loan payments. They represent the post-housing income a disability benefit must replace to maintain basic financial stability during a training-year claim. The benefit sizing decision belongs in that range.

The $3,536 that a WashU PGY-1 resident takes home after rent is the number that belongs on the enrollment form. It is not a coastal comparison and not a reputation. It is the St. Louis figure, and the GSI benefit amount written into the policy on the first day of residency is what carries it forward.
