Frequently asked questions
Are NumberPilot's calculators free to use?
Yes. Every calculator on NumberPilot is completely free, with no signup, account, or subscription required. There are no usage limits.
Do you store the numbers I enter?
No. All calculations run entirely in your browser. The values you type are never sent to our servers. Optionally, we save only the names of calculators you've used in your browser's local storage so we can show a 'recently used' list — you can clear this anytime.
How accurate are the results?
Our calculators use standard, well-established financial formulas and are unit-tested for accuracy across a wide range of inputs. That said, results are estimates for educational purposes and don't account for every real-world variable, so they shouldn't be treated as financial, tax, or legal advice.
Can I use NumberPilot on my phone?
Absolutely. NumberPilot is built mobile-first and works smoothly on phones, tablets, and desktops, with fast load times and responsive layouts.
Will you add more calculators?
Yes. NumberPilot is built on a scalable architecture designed to grow into hundreds of calculators across loans, mortgages, investing, retirement, salary, credit, and everyday math.
