Frequently Asked Questions
Are these calculators really free?
Yes — completely free, no sign-up, no email address required. Just enter your numbers and get an instant answer. All calculations happen in your browser and your data is never stored.
How accurate are the results?
Our calculators use standard, industry-accepted financial formulas and are highly accurate for the data you provide. That said, they are for informational purposes only and should not be taken as professional financial advice. Always consult a qualified adviser for major decisions.
What’s the difference between a calculator and a premium template?
Our calculators give you a quick answer to one specific question — great for a fast sense-check. Our premium templates are full multi-tab spreadsheets that let you build a detailed financial model (such as a 5-year cash flow forecast or a complete business budget) that you can save, edit, and share.
Can I use these calculators on my phone?
Yes. All of our calculators are fully responsive and work on any device — phone, tablet, or desktop. No app download required.
