Calculate SimplyHow to use
Start with the worked example to understand the inputs, then replace every relevant value with your own figures. Use one currency and consistent units throughout. Add or remove rows where offered; irrelevant conditional fields are disabled and excluded. Select Calculate after editing. Review negative values and any “not determined” result rather than assuming every scenario must be profitable. Download a text summary or print the page for your records.
Formula and assumptions
Engagement rate uses average likes, comments and shares per post divided by followers. Keep all counts on the same post sample and time period. Quote scenarios multiply expected views by a manually entered sponsorship CPM, then add production and usage-rights fees. CPM means price per thousand views; it is not the creator’s ad revenue RPM. The lower and upper CPM values are illustrative assumptions, not verified niche benchmarks. Exclusivity, deliverables, licensing duration and audience geography can change a real agreement.
ER = (likes + comments + shares) / followers × 100; quote = views / 1000 × CPM + production + rights

Frequently asked questions
Are the example rates current market prices?
No. Example inputs demonstrate arithmetic, not live prices, tax rules, salary surveys or sponsor benchmarks. Enter a dated quote, bill, manufacturer specification or verified fee schedule that applies to your situation. Compare a conservative and an optimistic scenario separately.
Why is a result not determined?
Some calculations have no meaningful value when a denominator is zero, savings are non-positive, a target cannot be reached or your data do not bracket an intersection. The tool leaves that result undetermined instead of displaying infinity or inventing a recommendation. Check the method and your inputs.
