# What is an earn rate?

Earn rate is how fast a customer builds up credit. One stamp per coffee, say, or a set number of points per dollar. Together with how much is needed for a reward, it decides how long the programme takes to pay off.

Earn rate and threshold are two halves of one decision. Changing either changes
how long the programme feels.

## Stamps make it simple

In a stamp programme the earn rate is usually one stamp per item, so the number
needed for a reward does most of the work.

## Points give you a second lever

In a points programme you can adjust earn rate and threshold independently,
which is more expressive and correspondingly easier to get wrong. Change one at
a time.
