Frequently asked questions
Are these marketing tools really free?
Yes. All 10 calculators are free, need no sign-up or email, and run in your browser. You can download any result as a PDF.
How do I download my result as a PDF?
Open any tool, enter your numbers and press the Download PDF button. Choose 'Save as PDF' in the print dialog to keep a clean, branded copy.
Which tool should a founder start with?
Start with the ROAS & break-even ROAS calculator if you run ads, the CAC & LTV calculator if you are raising or planning growth, and the UTM builder before launching any campaign.
Are the numbers built for India?
Yes. Every tool works in rupees and uses Indian number formatting; benchmark hints reflect typical Indian ranges.
Do you store the data I enter?
No. Calculations happen in your browser and nothing you type is sent to us.
These are models, not oracles.
Every calculator here is built on assumptions we've documented on each tool page. They're closer to reality than the "let's just multiply spend by 4×" model most agencies pitch. They are not a substitute for a real engagement, a real audit, or a real look at your data. If a number here changes your quarter, please talk to us before you sign the cheque.
