Business & Marketing Calculators

Compute profit, margin (share of revenue), and markup (share of cost) from cost and selling price — and stop confusing the two.

Find how many units you must sell to cover fixed costs, from price and variable cost per unit — with impossible price setups flagged honestly.

Compute return on investment from cost and final value, with an optional holding period for the annualized rate that makes investments comparable.

Compute return on ad spend and — from your profit margin — the break-even ROAS below which ads lose money even when revenue looks healthy.

Work backwards from target conversions: your conversion rate and your average CPC give the clicks and budget required, monthly and daily.

Compute customer acquisition cost from total marketing and sales spend, and optionally the LTV:CAC ratio investors actually look at.

Solve any of cost, impressions, or CPM from the other two. The standard cost-per-mille formula, instantly and privately in your browser.

Solve cost, clicks, or cost-per-click from the other two values — the basic unit economics of any paid traffic campaign.
