Two funds, two clocks
Social Security is not one account. Retirement and survivor benefits are paid from the Old-Age and Survivors Insurance trust fund; disability benefits are paid from the Disability Insurance trust fund. Each has its own income, its own reserves and its own projected depletion date.
| Fund | Depletion | Payable afterward |
|---|---|---|
| OASI (retirement and survivors) | Q4 2032 | 78% |
| OASDI (OASI + DI combined) | Q3 2034 | 83% |
| DI (disability) | None projected | 100% through at least 2100 |
| HI (Medicare hospital insurance) | Q2 2033 | 89% |
The two Social Security dates are not contradictory. They answer different questions: when does the retirement fund alone run short, and when does the combined program run short.
Why combining pushes the date out
Disability Insurance is in comparatively good shape, projected to pay full benefits through at least 2100. When the two funds are analyzed together, the surplus in DI offsets part of the OASI shortfall, which is why the combined depletion date lands roughly eighteen months later.
That arithmetic is also why the combined figure is the more favorable-looking of the two and the one most often quoted. It describes a hypothetical pooled system, not the statutory separation of the funds as they currently operate.
What depletion does not mean
Depletion means reserves reach zero. It does not mean the program has no money. Payroll tax revenue continues to arrive every month, and under the 2026 projections that revenue alone would cover 78% of scheduled OASI benefits, or 83% on a combined basis.
Three implications follow:
- The projected cut is a percentage, not a shutdown. A benefit of $2,170 would be reduced proportionally, not eliminated, if the projection held and no law changed.
- The projection is conditional. It assumes current law and current demographic assumptions. Legislation, immigration, wage growth and fertility all move the date.
- The report is annual. Each edition revises the numbers, and the long-run trend has been more sensitive to economic assumptions than to any single year’s data.
The headline dates rest on the intermediate assumptions. The report also publishes stochastic projections that express solvency as a probability distribution, and those ranges are wider than any single date suggests.
What it means for a decision made now
Nothing in the 2027 figures depends on the depletion dates. The wage base is $192,300, the COLA is 3.6%, and the benefit formula is unchanged. Claiming decisions and payroll planning should be made on those figures, not on a 2032 headline.
The date worth watching is not the one that makes a better headline. It is whichever date survives the next report with the same set of assumptions behind it.
