Store conversion is the share of visitors who buy: transactions divided by footfall. Sales per visitor combines conversion with how much each buyer spends.

Also called: Retail conversion rate calculator, Store traffic conversion calculator.

## Inputs
- Visitors (footfall) (default 2400)
- Transactions (default 528)
- Sales (default 31680; optional)
- Currency

## Results
- Conversion rate
- Average transaction value
- Sales per visitor
- Visitors who did not buy

## Formula

```
Conversion = Transactions ÷ Visitors × 100;  ATV = Sales ÷ Transactions;  Sales per visitor = Sales ÷ Visitors = Conversion × ATV
```

Where:
- Visitors: people counted entering the store
- Transactions: completed sales at the till

## Worked example
1. Conversion = 528 ÷ 2400 × 100 = 22%.
2. ATV = 31,680 ÷ 528 = 60; sales per visitor = 31,680 ÷ 2400 = 13.20.

**Result:** 528 sales from 2,400 visitors is a 22% conversion rate; at $60 a transaction, each visitor is worth $13.20.

## What the result means

Track conversion by hour and day against staffing: low conversion in busy hours often points to queues or too few staff on the floor.

## Assumptions and limits
- Each transaction comes from a separate visit.
- Door counters count groups and staff differently; correct for them before comparing stores.

## Questions

### Should I count groups as one visitor?

Ideally yes, since a family usually makes one purchase. Many counters can be set to discount groups and staff.
