About
About This Website
Retirement planning tends to collapse into a single number — "your number" — as if hitting it settles everything. It doesn't. The number matters less than understanding what's driving it: the savings rate, the Social Security timing, the healthcare cost assumption, the market return you're betting on. Change any one of those and the number moves. MyRetireNumber is built to show that movement, not hide it behind a single static figure.
How These Calculators Are Built
Every calculator here is built on a transparent research and review process. Each formula is grounded in Social Security Administration guidance, IRS rules on retirement account contributions and withdrawals, and Medicare cost data. Where official guidance from different sources doesn't fully agree, that disagreement is researched before an approach is chosen.
Before publishing, every calculator goes through multiple rounds of review: calculations verified, assumptions challenged, edge cases tested, and results checked against the methodology behind them. Independent review tools, including AI-assisted analysis, help catch inconsistencies, math errors, or outdated figures.
Why the Assumptions Are Visible
A retirement estimate is only as good as the assumptions behind it, and assumptions vary enormously by situation — expected returns, inflation, healthcare inflation, longevity, Social Security claiming age. Every one of those is shown here, editable, rather than buried behind a single confident-looking output.
Educational Information — Not Professional Advice
This is an educational tool for exploring retirement scenarios. It's built to help organize your thinking and prepare sharper questions for a financial advisor, CFP, or Social Security specialist.
A Commitment to Improvement
Rules change: contribution limits, Social Security estimates, Medicare costs, tax treatment. When something here goes out of date or turns out to be wrong, it gets fixed. Feedback can be sent to hello@answerworth.com.
Don't trust a result simply because it appears on this website. Trust it because you can see how it was calculated, examine the assumptions, and decide for yourself whether the reasoning fits your situation.
