About Retirement Lab

“We built Retirement Lab because you shouldn’t have to choose between a calculator that’s easy to use and one that gets the math right.”

Precision

Real tax modeling across 25+ countries — bracket-based income tax, capital gains, and wealth tax where applicable. Monte Carlo simulation with fat-tail distributions so your projections account for the way markets actually behave, not just textbook assumptions.

Usability

A fast, clear interface that doesn’t feel like a spreadsheet. Build scenarios in minutes, compare countries side by side, and understand your results without a finance degree. The simulation does the heavy lifting — you make the decisions.

Retirement Lab is built by Cedarwell Labs.
