Free advertising calculators
Free advertising calculators for ROAS, CTR, CPM, LTV and CAC help operators calculate the basic metrics that still drive paid media decisions. The calculators are intentionally simple, but the surrounding page explains how those numbers fit into campaign structure, creative testing, attribution, and budget control.
What are advertising calculators?
Advertising calculators are free tools that turn campaign inputs into the basic metrics paid media decisions depend on.
- ROAS from revenue and spend
- CTR from clicks and impressions, CPM from cost and impressions
- LTV from order value, frequency, lifespan and margin
- CAC from acquisition spend and new customers
Five numbers, and what each one decides
Advertising calculators are only the first step
ROAS, CTR, and CPM are useful when they are interpreted together.
- Use ROAS to evaluate revenue efficiency.
- Use CTR to detect creative and audience fit.
- Use CPM to understand delivery cost and market pressure.
Turn formulas into campaign decisions
The calculators help with quick checks.
- Connect calculator outputs to campaign workflows.
- Compare metric changes against creative and attribution context.
- Move from manual checks to automated monitoring.
Pick the metric you need
Each calculator includes the formula, examples, FAQ, and links back to the workflow where that metric becomes actionable. The benchmarks shown on each page are industry averages meant for orientation, not targets to optimize toward.
ROAS Calculator
Calculate return on ad spend from revenue and ad cost, then compare the result against campaign decisions.
CTR Calculator
Calculate click-through rate from impressions and clicks to evaluate creative attention and placement fit.
CPM Calculator
Calculate cost per thousand impressions, total cost, or impressions depending on which input you know.
LTV Calculator
Calculate customer lifetime value from order value, frequency, lifespan, and margin, then compare it against CAC.
CAC Calculator
Calculate customer acquisition cost from marketing and sales spend, then compare it against lifetime value.
Get started in 5 steps
Enter the campaign inputs
Spend, impressions, clicks or revenue — the calculator solves for the rest.
Read the result beside its neighbours
A metric on its own misleads; pair it with CTR, conversion rate and revenue.
Check it against the benchmarks
Industry averages on the page are orientation, not targets.
Connect an account for live numbers
The same metrics, computed from real spend and revenue instead of estimates.
Let attribution replace the estimates
ROAS, CPA and LTV are read against real paying users from then on.
