Money & Margin

Why the First Number Sticks

One number can bend what feels fair, cheap, or normal before you think clearly.

The first number sets the frame

If you see a {{money:2000|USD}} watch first, the {{money:400|USD}} watch next to it suddenly looks reasonable.

That is the anchor doing its job before you have even decided what the item is worth to you.

The Anchor Lands First

Once the middle number arrives first, the cheaper and pricier options both start orbiting it like it is objective truth.

Set the Starting Point

The brain leans hard on the first number it sees.

Later prices get judged relative to that first number, even when the first number was picked to manipulate you rather than inform you.

Daniel Kahneman and Amos Tversky proved in 1974 that even explicitly random numbers (like a roulette wheel spin) strongly anchor people's estimates of completely unrelated facts.

The Luxury Decoy Trick

Menus do this constantly.

One absurdly expensive option exists so the merely expensive one feels sensible. Pricing pages do it too: show {{money:99|USD}} first and {{money:29|USD}} feels cheap. Show {{money:9|USD}} first and the same {{money:29|USD}} feels ridiculous.

Quick check

Knowledge Check

Why do subscription pages always highlight the most expensive tier first?

  1. Because it's the best product.
  2. To anchor your expectations extremely high, making the middle tier feel cheap.
  3. As a mistake in UX design.

Why:

  • If they show you {{money:99|USD}}/mo first, {{money:29|USD}}/mo feels like a huge discount.
  • If they showed you {{money:9|USD}}/mo first, {{money:29|USD}}/mo feels like a rip-off.

Try this

Ignore the comparison price

Ignore the crossed-out 'original price' on sale items. Ask one cleaner question: 'Would I pay {{money:40|USD}} for this right now if no other number was shown?' If the answer is no, the discount probably does not matter.

Try this

Set Your Price First

Before opening a pricing page, decide your own ceiling first: 'For this, my max is {{money:18|USD}} a month.' Your number needs to arrive before theirs does.

Key idea

What to remember

The first price or number is usually trying to set the frame. Slow down, name what you actually want, and decide from usefulness instead of comparison.

The first number is often bait, not truth.
