# Comment-to-DM Calculator

This comment-to-DM calculator turns your views and rates into keyword comments, DMs, link taps, sales and revenue, per post and per month. It is for creators and AI persona pages that sell a product or an affiliate link through comment-to-DM.

## How to use the Comment-to-DM Calculator

1. Type your views per post and how many posts you make in a month.

2. Add your own rates from past posts: keyword comments, link taps and sales. Add what you earn per sale.

3. Read the estimate per post and per month, the DMs it needs, and which step gains most from one more point.

## How the comment-to-DM funnel works

1. **Views.** People watch the post and hear the ask: comment a keyword.
2. **Keyword comments.** Each keyword comment gets one DM with your link. Views × comment rate.
3. **Link taps.** Some people open the DM and tap the link. Comments × tap rate.
4. **Sales.** Some of them buy. Taps × buy rate.
5. **Revenue.** Sales × what you earn per sale: your price, or the affiliate commission.

The calculator counts one DM per keyword comment. The real number can be lower. Each person gets an automation’s DM once. A comment with a skip word gets none. And Meta allows a DM only within 7 days of the comment.

## Which number moves the result most

Every step multiplies the next. So making any one rate 10% better makes the result 10% better. Percentage points work differently: one more point on a small rate is a big change, so the lowest rate usually gains most. The calculator shows what one more point on each step adds.

- **Comment rate:** say the keyword in the video, show it on screen and write it in the caption. Say clearly what the DM sends.
- **Link tap rate:** keep the DM short and put the link on its own line near the top. On Instagram, write the link in the text.
- **Buy rate:** this one is about the offer: what the link opens, the price and the page it lands on.

Send your link by DM to everyone who comments your keyword on Instagram or a Facebook Page, and see the comments, DMs sent and DMs failed for each automation. [See how comment-to-DM works →](https://phersa.com/comment-to-dm)

## Comment-to-DM Calculator questions

### Is the result what I will earn?

No. It is an estimate from the numbers you type. Views, comments and sales change from post to post. Use it to compare scenarios, not as a forecast.

### What is a good comment rate on a comment-to-DM post?

There is no single good rate. Use your own from past posts: keyword comments divided by views, times 100. Rates differ a lot between niches, offers and accounts, so someone else’s number tells you little about yours.

### How do I measure link taps?

Use a link that counts its clicks, like your store’s analytics or a link with UTM tags. Then divide the taps by the DMs your automation sent.

### Does every keyword comment get a DM?

No. Meta allows one DM per comment, sent within 7 days of it. Each person gets an automation’s DM once, even on another post that automation covers. A comment with a skip word gets none. So DMs can be fewer than keyword comments.

### How do I know which post made the sale?

Give each post’s link its own label: UTM tags for your own store, or a separate tracking ID for Amazon links. Then read sales by that label in your store or Amazon Associates reports.
