A Better Retirement Calculator Than an Excel Spreadsheet
Excel retirement templates require you to wire the formulas yourself, maintain them as tax law changes, and re-run projections manually. Reise Tools is purpose-built — employer match modeling, 4% SWR analysis, Fidelity benchmark checks, and Social Security estimation, all pre-wired with every formula visible.

To be honest: this is a widely-used tool for good reasons. Here's what it does well.
- Fully customizable — Excel lets you model any scenario, add any variable, and structure the sheet however you want
- No dependency on a third-party service staying online — your spreadsheet works offline forever
- Version history and auditability if you keep the file in SharePoint or Google Drive
- Many free retirement templates available from Fidelity, Vanguard, and financial blogs
- ▸You have to build and maintain the formulas — most retirement templates use =FV() and =PMT() but don't account for employer match phase-outs, Roth vs Traditional tax treatment differences, or inflation-adjusted withdrawal rates. The math you miss is what costs you.
- ▸No readiness score or benchmark — a spreadsheet gives you a projected balance, but it doesn't tell you if you're on track relative to your age (Fidelity recommends 1× salary by 30, 3× by 40, 6× by 50, 8× by 60). Reise surfaces this automatically.
- ▸Social Security estimation is manual — most Excel templates don't include Social Security income because it requires your earnings history. Reise includes an estimator that inputs your annual income and projects a benefit.
- ▸4% rule (SWR) isn't usually pre-built — the safe withdrawal rate calculation requires converting your projected balance into annual income and comparing it to your expense target. Easy to forget or miscalculate in a spreadsheet.
- ▸No mobile-friendly updates — adjusting your Excel model on a phone mid-conversation with a financial advisor is painful. Reise works on any device.
