Telegram Ad Results Calculator: Cost per Retained Member & ROI (Free)

Which Telegram ad really worked? Compare campaigns by members who stay.

A cheap ad that brings members who leave a week later is not cheap. Enter the cost, joins and how many members stayed for up to four campaigns, and see which one actually paid off.

How to measure a Telegram promotion

One invite link per campaign. Create a separate invite link for each ad or placement; the link shows how many people joined through it. Make links with the link generator.
Count joins from that link after the ad has run.
Count again after 7 or 30 days. Use your channel statistics or your own records to estimate how many of those members are still subscribed. Use the same day count for every campaign.
Track what matters to you: link clicks from a tracked link, sales, sign-ups or leads, and the revenue they brought.

What the numbers mean

Cost per join = cost ÷ joins.
Retention = members still subscribed ÷ joins.
Cost per retained member = cost ÷ members still subscribed. This is the fairest way to compare placements.
Join rate from clicks = joins ÷ link clicks.
Cost per conversion = cost ÷ sales or leads; ROI = (revenue − cost) ÷ cost.

These are simple ratios of your own numbers, not market benchmarks.

Choosing your next placement

Before you pay a channel, check its audience with the free channel audit, and if you sell ads yourself, send advertisers a report with the media kit generator. If your goal is a higher visible member count rather than conversions, compare with Telegram members packages; they raise the count, while activity still depends on your content.

Frequently asked questions

How do I measure the results of a Telegram ad?

Give each ad its own invite link, count joins from that link, count how many are still subscribed after 7 or 30 days, and compare the cost per retained member.

What is a good cost per subscriber on Telegram?

It depends on niche, language and placement. Compare your own campaigns by cost per retained member rather than relying on a general benchmark.

Why is cost per retained member better than cost per join?

Because members who leave quickly have no value. A placement with a higher cost per join can be cheaper per member who stays.

How do I calculate ROI for a Telegram promotion?

Subtract the ad cost from the revenue it brought and divide by the cost. For example, $40 spent and $100 earned is +150% ROI.
