Quick answer: Retirement Calculator
Project nest egg at retirement from contributions, return, and years - and sometimes a spend-down sketch.
Example: $650/mo from 35 to 65 at ~6.5% nominal → ~$720k ballpark; 4% rule suggests ~$29k/year before tax - sanity-check against your spend.
Calculations follow the documented formula on this page; rounding and input units can change the last digit—treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
What this calculator does
- Retirement Calculator
- Estimate retirement corpus target.
Sequence-of-returns risk near retirement can swamp average returns. Inflation turns a pretty number at 65 into canned beans at 85 - index expenses, not just balances.

Key takeaways
- Healthcare before Medicare is a common stealth cost - model COBRA or ACA.
- Catch-up contributions at 50+ are real money, not a brochure footnote.
- Social Security estimates belong in the sheet - download your statement.
