What's it called when you charge someone 10% more on a better product?

It’s 1,000% markup, not 10%. Not sure of the name. It’s very niche/bespoke though.

10% of 7500 is 750. 7500 + 750 is not 75000.

@jca2 7,500 * 10% = 750,
whereas 7,500 ÷ 10% = 75,000.

It isn’t competition. In economics it is called substitute luxury and inferior goods. They each have their own demand curve,

You are making an analogy simlar to comparing a Lamborghini to a Miata. Both are two seater convertibles, but that is about where the similarity ends.

Also, when applying the percentage of markup, one multiplies, not divides.

@gorillapaws Thanks. Got the percentage wrong.

@zenvelo Thanks.

Bait and swindle.

Looks like it’s actually 10x, not 10% more. In engineering, sometimes 10% more actually costs 10x more if the baseline is already difficult to do. In art – I don’t know.

Common sense.

It depends on what the customer is willing to pay.

Upselling – and a lot of people resent it, no matter how much “better” the other product may be.
