Use a constant real return to illustrate a spending amount that exhausts savings at the horizon.
This retirement spending calculator illustrates how long will my money last in retirement and how long will my retirement savings last if you take a level annual amount.

Assumptions
- Uses a level inflation-adjusted withdrawal that exhausts savings at the end of the horizon if returns match the input.
- If these savings were all pre-tax, the RMD uses the current IRS Uniform Lifetime Table and SECURE 2.0 start ages.
- Illustrated federal tax treats the annual spend as extra ordinary income on top of other income (2026 IRS brackets).
- State tax uses the shared 2026 California engine (2026-enacted-v1; progressive brackets). California excludes Social Security benefits from state taxable income.
- MAGI is below the first 2026 IRMAA threshold ($109,000 for this filing status). Estimated Part B is $202.90/mo.
- Rule year 2026: IRS federal income tax (2026-rev-proc-2025-32) and California state rules (2026-enacted-v1; progressive income tax). Medicare IRMAA, HSA, 401(k), and RMD tables are federal.
