About Cuetils

Cuetils is a collection of free financial calculators built for money decisions people actually face. Not just “what does this compound to” but “should I rent or buy”, “prepay the loan or invest”, and “how long will my corpus really last once inflation shows up”.

Every tool states its assumptions on the page, runs entirely in your browser, and stores nothing you type. The math is unit-tested against closed-form financial formulas.

These calculators are educational tools, not investment, tax or legal advice. For decisions involving significant money, consult a licensed financial adviser or a qualified tax professional.
