Free calculators and tools for ecommerce and DTC brands

Small tools for the math and the listening that come up constantly when running an ecommerce or DTC brand — profit, ad spend, fees, acquisition cost, customer feedback and creators. Everything runs in your browser: no signup, no email, nothing saved or sent anywhere.

What are people saying about your brand?

What does an order really leave you?

What does a customer cost, and what are they worth?

Questions about these tools

Are these actually free, no catch?
Yes. No signup, no email required, no usage limit. They run in your browser — the arithmetic happens locally and nothing is sent to a server, saved, or used for anything.
Do you store the numbers I enter?
No. Nothing you type into any of these calculators is saved, logged or sent anywhere — it exists only in your browser tab and disappears when you close or refresh it.
Why did Mentionfront build these?
We work through most of this math ourselves — margin, ROAS, acquisition cost — while building an ecommerce product, and figured other people doing the same work could use the same calculators. A few, like the influencer ROI and MER calculators, connect back to what Mentionfront actually does (tracking the organic conversation that attribution links miss); most don't, and that's fine — see social listening for ecommerce if you're curious what the product itself does.
Which one should I start with?
If you're running paid ads, start with the break-even ROAS calculator — it's the one number most of the others (ROAS, MER, free shipping thresholds) ultimately get compared against. If you're sourcing physical product, start with landed cost instead.
