CalculatePilot
158 free calculators, every formula explained, zero signup
Most calculator sites feel like they haven't been touched since 2009 — cluttered, slow, and vague about how they actually get their answers. CalculatePilot is the opposite: fast, clean, and transparent.
What's inside:
40+ financial calculators (mortgage, loan, retirement, rental yield, house flip ROI, freelance rate)
30+ health & fitness calculators (BMI, TDEE, macros, pregnancy, VO2 max)
40+ math calculators (algebra, statistics, trigonometry, complex numbers, sequences)
45+ everyday calculators (GPA, tip splitting, moving costs, pet age, gas mileage)
Every calculator shows the formula and methodology behind the result — no black boxes. No sign-up, no account, nothing sent to a server. Multi-currency support built in (20 currencies) so it's not just a US-only tool.
Built by a small team that wanted a calculator site that respects your time and shows its work.

"Zero signup" is a bold trust play — but are you targeting students who want homework help, or professionals who need quick calculations? The student wants explanations and learning. The pro wants speed and accuracy. Your "formula explained" feature is gold for one and friction for the other.
