About ClearPathCalc

What this is

ClearPathCalc is a free suite of financial, business, health, and sustainability calculators. Every tool runs entirely in your browser — nothing you enter is sent to a server or stored anywhere. There is no account, no signup, and no paywall.

Why formulas are shown, not hidden

Most calculator sites give you a number and ask you to trust it. ClearPathCalc shows the formula and reasoning behind every result, so you can verify the math yourself or adapt it to your own numbers. That transparency is the entire point of the project.

Who maintains it

ClearPathCalc is built and maintained independently. If you find an error in a formula, have a correction, or want to suggest a new calculator, get in touch — corrections are taken seriously and applied directly to the live tools.

How it's funded

The site is supported by display advertising, which is what keeps every calculator free and account-free. Ad placement is scoped to not interfere with the tools themselves.
