Why AdCalcLab
AdCalcLab is built and maintained by RankYouUp, a digital marketing agency that manages live Meta and Google Ads accounts for ecommerce and service brands every day — this isn’t a generic calculator farm bolted together to catch search traffic. Every formula on this site is one we actually use internally to make real decisions on real ad budgets, from break-even ROAS on a new campaign to what to charge a new freelance client.
That’s also why the tools stay narrow and specific instead of trying to be an all-in-one dashboard: a calculator that does one thing well, shows its formula, and gives you a straight answer is more useful mid-workday than a bloated tool that needs a login and a tutorial.
- Every formula is shown on the page, not hidden behind a “black box” result.
- Nothing you enter is saved, tracked, or emailed — each calculator runs entirely in your browser.
- No signup, no paywall, no artificial limit on how many times you can use a tool.
Frequently Asked Questions
Are AdCalcLab’s calculators really free?
Yes — all 8 calculators on AdCalcLab are 100% free, with no signup and no email required. Enter your numbers and get results instantly in your browser.
How do I calculate ROAS?
ROAS (Return on Ad Spend) = Revenue ÷ Ad Spend. That gives you the headline number, but your real break-even ROAS also depends on product cost and other costs — use the ROAS calculator to get both in one step.
How do I calculate CAC?
Customer Acquisition Cost (CAC) = Total Sales & Marketing Spend ÷ New Customers Acquired. Compare it against your Customer Lifetime Value (LTV) with the CAC calculator and LTV calculator to see if your unit economics work.
What should I charge per hour as a freelancer?
It depends on your income goal, taxes, expenses, and how many hours you actually bill (not just work). The Freelance Hourly Rate Calculator works backward from your target income to a real hourly and day rate.
How much should I spend on marketing?
It depends on your business stage — startups typically weight paid ads heavily for fast signal, while established businesses shift more toward content, email, and retention. The Marketing Budget Calculator gives you a starting split by stage.
What’s a good profit margin for a small business?
It varies a lot by industry — service businesses often run 50–80% gross margin, while ecommerce is often 20–50%. Use the Profit Margin Calculator to see your own numbers and break-even revenue.
Do I need to sign up to use these tools?
No. Every calculator on AdCalcLab runs entirely in your browser — no account, no email gate, and nothing is stored or sent anywhere.
Who built AdCalcLab?
