What happens if I change a product's price in Shopify? Will my percentage-based discounts update automatically?

Price Changes and Percentage-Based Discounts

Percentage discounts are calculated dynamically against the current product price at the time of purchase. This means they automatically adjust when you change base prices - which simplifies price management but also requires awareness of how price changes interact with active campaigns.

How Price Changes Affect Discount Types

Important Case: Price Increase with Active Discount

If you raise a product's price while a percentage discount is running, the customer pays less than the new full price but more than if the price hadn't changed. Example: product was $50 with 20% off campaign. You raise price to $60. With the same campaign, customer now pays $48 instead of $40. This is usually fine, but worth tracking if you're running a "15% off this week" promotion that you advertised at a specific price point.
