About CalcAhead
Free online calculators for loans, GPA, concrete and everyday math.

Loans include a cent-rounded monthly schedule with CSV export; GPA supports cumulative, target and weighted courses; home tools cover concrete, fencing and snow removal. Everything runs locally in the browser with no signup and no ads on results.
