The endowed progress effect is the tendency to work harder toward a goal when we feel we have already made some progress—even when that progress was given to us for free.
Example
Imagine two coffee shops offering loyalty cards:
- Card A: Buy 8 coffees and get one free. The card starts with 0 of 8 stamps.
- Card B: Buy 10 coffees and get one free, but the shop gives you 2 stamps immediately. The card starts with 2 of 10 stamps.
Both customers still need to buy 8 coffees to earn the reward. Logically, the programs are identical.
However, people with Card B often feel:
“I’ve already completed 20% of the goal.”
That feeling of being underway motivates them to return more frequently and finish the card. The two free stamps create endowed progress.
Another everyday example
Suppose you want to study for three hours. Instead of thinking:
“I haven’t started yet.”
you begin by reviewing your notes for ten minutes and then tell yourself:
“I’ve already completed the first section.”
That small initial progress can make it psychologically easier to continue.
In simple terms, starting from 20% feels more motivating than starting from zero—even when the remaining work is exactly the same.
