Free Marketing Calculators

How these marketing metrics fit together

Each calculator measures a different link in the same chain, and reading them in order tells you where a campaign is winning or leaking:

• CPM and CTR describe your reach and creative — what you pay to be seen, and how often a view becomes a click.
• CPC is where those two meet: a low CTR pushes your cost per click up even when CPM is cheap.
• Conversion rate (CVR) and CPA measure the landing page and offer — whether the clicks you paid for actually turn into customers.
• ROAS and ROI are the scoreboard, rolling every step above into one revenue-versus-cost number.

When ROAS disappoints, walk the chain backward: a weak CVR points at the page, a high CPC points at targeting or creative. Every result here shows its formula, so you can see exactly which input to move.

Turn the numbers into spending limits

Two of these calculators set the guardrails for the rest. Break-even ROAS (1 ÷ profit margin) is the lowest return where ads stop losing money — a thin margin demands a much higher ROAS than a fat one, and hitting a “4×” means little until you know your own break-even. Customer lifetime valuethen sets your ceiling: as long as your CPA stays comfortably below CLV, you can afford to acquire a customer even when the first order barely breaks even. Read together, they turn a wall of metrics into one decision — how much you can pay for a click, a lead, or a sale.
