Lead to sale conversion rate is the share of your leads that become paying customers. If 212 leads bring 9 sales, your lead to sale rate is 4.2%.

## The formula

Lead to sale rate = sales / leads x 100

Use leads and sales from the same group, such as one week's leads, and count the sales those leads made, even if a sale closes weeks later. Mixing this month's sales with this month's leads flatters slow months and punishes fast ones.

## A worked example

Say a travel company gets 212 Meta leads in a week, for INR 84,200 of ad spend. The numbers are made up.

| Stage | Leads left | Rate from previous stage |
|---|---|---|
| Leads | 212 | |
| Contacted | 180 | 85% |
| Qualified | 64 | 36% |
| Quote sent | 30 | 47% |
| Booked (sale) | 9 | 30% |

1. Lead to sale rate: 9 / 212 x 100 = 4.2%.
2. Cost per sale: INR 84,200 / 9 = INR 9,356.

The stage table matters more than the single rate. Here, 32 leads were never contacted. Calling them and converting at the same rates as the rest would add one or two sales a week, with no extra ad spend.

## How to raise it

- **Fix the earliest leak first.** The Contacted step is the cheapest to improve. Faster calls and a retry rule help most.
- **Tighten the form.** One sharp question on the instant form filters out people who were never going to buy. See [lead ads vs a landing page](/compare/lead-ads-vs-landing-page).
- **Script the first call.** A clear first call moves more leads to Qualified.
- **Tell Meta who bought.** Send your stages back with the [Conversions API](/glossary/conversions-api), so delivery shifts towards people like your buyers.

Your lead to sale rate also sets how much you can pay per lead. If a sale earns INR 15,000 in margin and 4.2% of leads buy, each lead is worth about INR 630 to you. Compare that with your [CPA](/glossary/cpa) target. We make Marxx, which records each Meta lead's stage so you can count sales by the ad that brought them. See [Marxx leads](/features/leads).

## FAQ

### What is a good lead to sale rate?

It depends on price and sales cycle. A high-ticket home sells to a far smaller share of leads than a low-cost course. Compare against your own past months.

### Should I use leads or qualified leads?

Track both. Leads to sale shows the whole funnel. Qualified leads to sale shows how well sales closes.

### How long should I wait to count sales?

As long as your usual sales cycle. If most bookings happen within 30 days, report each week's leads 30 days later.
