Frequently asked questions
What are these marketing calculators for?
They cover the everyday math of running campaigns and a business: return on investment and ad spend, cost per click and per thousand impressions, click-through and conversion rates, profit margin, customer lifetime value and acquisition cost, A/B test significance, discounts, and PayPal fees. Each is a focused, single-purpose tool.
Are the calculators free?
Yes, every calculator is free with no signup and no limits. They all run entirely in your browser.
Do you store the numbers I enter?
No. The calculations happen on your device and nothing is sent to a server. Each calculator remembers your last entries locally so it is ready next time, and you can clear them with Reset.
Which calculator should I use?
Pick by the question you are answering: ROAS or ROI for campaign profitability, CPC and CPM for ad pricing, CTR and conversion rate for funnel performance, margin for pricing, LTV and CAC for unit economics, and the A/B test calculator to know whether a test result is real.
Can I put these on my own website?
The calculators themselves are not embeddable, but you are welcome to link to them from your site. If you want tools you can embed, our SEO tools (keyword research, backlinks, site audits, and more) support embedding, see the embed option in the site footer.
