FAQ
Frequently asked questions
The short answers to what people ask most. Each calculator also explains its own formula on its page.
- Is GrowthCalc really free?
- Yes. Every calculator is free and works straight away, with no signup, no trial and no usage limits.
- Do I need an account?
- No. Type your numbers and get the answer. There is nothing to install and nothing to sign up for.
- How accurate are the calculators?
- Each one uses the standard, widely-accepted formula for its metric, shown on the page next to the result. It is a fast, reliable way to sanity-check your numbers, not a replacement for your own analytics.
- What do the healthy and watch badges mean?
- Some calculators compare your result to a common rule of thumb, like a ROAS above 3.0x or an LTV to CAC ratio of 3 to 1. These benchmarks are conventions, not laws. The right target depends on your margins and model, so treat the badge as a starting point.
- Do my numbers stay private?
- Yes. Every calculation runs in your browser. The spend, revenue and other figures you type are never sent to our servers or stored anywhere.
- Can I use GrowthCalc in any currency?
- Yes. Money calculators have a currency toggle for dollars, pounds and euros. It swaps the symbol only; the math is the same in any currency.
