Built a CPM calculator that works in both directions
Most CPM calculators only solve one way. You type in your budget and impressions and get a CPM rate. Fine, but that's only one of three things you might need to know.
CPMCalculator.ai lets you enter any two values and calculates the third. Planning from a budget? Working backwards from a CPM rate? Trying to hit an impression target? All covered.
Expanded it into a full suite covering CPC, CTR, ROAS, Reach, eCPM, and Instagram ad costs. There's also a CPM benchmarks page with average rates broken down by industry, platform, and ad format for when you need a sanity check on a number.
Useful for media buyers, agency planners, or anyone running paid social who wants a quick answer without opening a spreadsheet.
Free, no account needed.
Would love feedback from anyone in programmatic or paid social. Happy to add more calculators if there are gaps.
Nice, being able to calculate CPM both ways is actually really practical.
This tool is a game-changer for media buyers, letting you calculate CPM, CPC, CTR, ROAS, and reach seamlessly from any two variables, saving time and boosting campaign planning accuracy. Its benchmarks and full suite make it ideal for quick, data-driven decisions without spreadsheets or accounts.
