Why ClearCalc
Most online calculators bury a simple answer under pop-ups, email gates and a wall of unrelated content. ClearCalc takes the opposite approach: one decision per page, a result you can read in a second, and a plain-language explanation of how it was reached.
The tools are free because they're supported by unobtrusive ads — never by selling your data or hiding the answer behind a sign-up. Calculations run entirely in your browser, so the numbers you type never leave your device.
Every estimate is exactly that: a starting point for a conversation with your accountant, lender or financial planner, not a replacement for professional advice.
