App Store storefront
A country or region where the App Store sells apps. Apple currently lists 175 storefronts for auto-renewable subscriptions, each with its own currency and prices.
Base country
The storefront whose price you set first in App Store Connect. Apple proposes prices for every other storefront from it.
Price point
One of the fixed prices Apple allows in a storefront. There are about 800 per currency; in the US they rise in $0.10 steps up to $9.99 and $0.50 steps up to $49.99.
Equalization
Apple’s mapping from a price point in one storefront to the comparable point in every other storefront, based on exchange rates and taxes.
Price level index
The World Bank indicator PA.NUS.GDP.PLI: the ratio of the PPP conversion factor to the market exchange rate, with the US at 100. A value of 23 means goods and services cost about 23% of US prices.
Purchasing power parity (PPP)
An exchange rate at which the same basket of goods costs the same in two countries. PPP pricing scales app prices by the gap between PPP and market exchange rates.
PPP pricing
Setting a different price in each country in proportion to local price levels, so a subscription costs about the same share of a local budget everywhere.
Preserved price
A price kept for existing subscribers when you raise a subscription’s price for new subscribers.
Proceeds
What you receive after Apple’s commission and taxes. Proceeds change when VAT changes even if your customer price doesn’t.
Floor price
The lowest price you will charge in any country, used to keep price-level-adjusted prices from going too low.
