Everything you need to plan
retirement with confidence

Real tax math — not rules of thumb — for every province, territory, and US state. Built for Canada and the US from the ground up.

Tax & Projection Engine

The math other tools skip

Most retirement calculators use flat tax estimates. Cinderfi uses the actual brackets — federal, provincial, and state — for every year of your projection.

Full Federal + Provincial/State Tax

Real marginal brackets for all 13 Canadian provinces/territories and all 50 US states. Not estimates, not flat rates — actual math.

Year-by-Year Projection

All Major Account Types
