Free Marketing Calculators
Eight free tools for brand marketers — from influencer ROI to paid media ROAS to AI search readiness. No sign-up required.
Common questions
Are these tools really free?
Yes. No signup, no card, no trial that expires into a paywall. Every calculator on this page runs entirely in your browser except the Fake Follower Estimator, which looks up a public Instagram handle and carries a fair-use limit so it stays available to everyone. Manual entry is unlimited on all of them.
Which tool should I start with?
It depends what you are deciding. Vetting a creator before paying: start with the Fake Follower Estimator, then the Engagement Rate Calculator. Deciding what to pay: the Rate Card Estimator. Planning a campaign: the Influencer ROI Calculator. Reviewing one that has run: the Campaign Benchmarker. Allocating a whole budget: the Budget Planner. Working out whether AI engines can see you at all: the GEO Readiness Scorecard.
Where do the benchmarks come from?
They are India 2026 bands, and each tool shows the ones it is scoring against on the page rather than hiding them. Engagement rate is banded by follower tier, cost per engagement by niche, and creator rates by format and niche. They are planning benchmarks: right enough to tell a good number from a bad one, and no substitute for your own historical data once you have it.
Do you store what I enter?
No. The calculators compute in your browser and nothing you type is sent anywhere or saved. The Fake Follower Estimator has to query a public profile to work, so the handle you check does reach our server; the result is cached briefly so repeated checks of the same handle stay fast, and nothing is tied to you.
Are these accurate enough to make decisions on?
They are accurate enough to change your mind, and not precise enough to be the last word. Each one is arithmetic applied to estimates, so the output is only as good as the inputs — which is why every tool shows its working. Use them to disqualify a bad creator, sanity-check a quote, or find out that a campaign only works under assumptions you do not actually believe.
How do these relate to the Nurdd products?
Each tool is a single decision taken from a product. Nia does creator discovery, TruAI follower analysis and campaign attribution properly, with account access; the influencer calculators here are the outside-in versions. Pulse connects to your ad accounts; the ROAS calculator is the manual equivalent. Noma tracks how AI engines actually describe your brand over time; the scorecard is the self-audit that comes before that.
