Frequently asked questions

Is QuickCalc really free?

Yes. All twenty calculators and converters are completely free and work without an account. An optional one-time Pro upgrade removes ads and lets you save calculations.

Do I need to create an account?

No. Every tool works instantly with no sign-up. You only need a free account if you buy Pro, so your upgrade and saved calculations can sync across devices.

What does QuickCalc Pro include?

Pro is a one-time $4.99 payment: no ads anywhere on the site, the ability to save calculations and revisit them on any device, and priority access to new tools as they launch.

How accurate are the results?

Calculators use standard formulas and, for currency, live exchange rates. Results are indicative and meant for everyday reference, not financial, medical or legal advice.
