Monte Carlo meets retirement math

Not another spreadsheet with a 7% assumed return. Thousands of simulated market scenarios give you probability-based projections. Model 401k, IRA, Social Security, RMDs, and tax impacts all in one place.

US tax modeling included

Year-by-year projections you can export

Knowledge Quiz

Know what you don't know

Test your understanding of investing fundamentals, pension systems, tax strategies, and withdrawal sequencing. Better decisions start with knowing where your blind spots are.

Not US-only

Most FIRE tools assume you live in America. RetireCrunch models Swiss pension pillars alongside US 401k and IRA, with 8 currencies. Built for the global FIRE community.

No advisory upsell

Empower uses their free calculator to funnel you into wealth management. Boldin gates critical features behind $120/year. RetireCrunch is free because it was built to solve a problem, not sell a service.

Real simulation

Static projections with fixed returns are comfortable lies. Monte Carlo runs thousands of market scenarios so you see the range of outcomes, not just the optimistic one.

Built by a practitioner

Created by a tech executive who spent 25 years in banking and couldn't find a free tool sophisticated enough for cross-border retirement planning. So he built one.

Retirement planning should be honest, not a sales pitch

RetireCrunch exists because the best financial tools shouldn't require a subscription or come with strings attached. Your financial future, modeled with real math.
