When Can I Retire?
Grow today’s savings plus monthly deposits to a nest egg = annual spend ÷ withdrawal rate. Age at that year is the earliest retirement age in this model.
Plug in your age, savings, monthly investing, and the income you actually want later. The date that comes back is the first year the 4% rule (or your own withdrawal rate) covers that income—not a promise from a brochure.

Practical guide
Using the When Can I Retire? well
Who this is for
Anyone who wants a first retirement year from savings, monthly investing, and the income they actually want later—not a brochure age.
Worked example
Age 34, $48,000 saved, $900/month at 7%, needing $42,000 a year at 4% → about $1.05M, around age 58 if the deposits hold.
What the year actually is
The page grows today’s pile plus monthly deposits until it covers annual spend divided by your withdrawal rate. Change spend or the monthly amount before you change the return. Social Security is not included unless you subtract it from the income field.
Common pitfalls
- Typing today’s full lifestyle as the retirement budget
- Using a 10%+ return to force an earlier year
- Ignoring a bad first decade of withdrawals

Very usable on mobile. Would love a save/export option later, but the math feels solid.
