How this service works
Final price and effective discount when percentage discounts are stacked one after another, versus simply adding them.
Output
Returns the final price after all discounts are applied sequentially, the effective discount percentage (true compounded rate), the simple additive discount percentage for comparison, total amount saved, a step-by-step breakdown of each discount stage (from/to price and discount applied), a human-readable summary and verdict, plus metadata like source and timestamp.
Example use cases
Retail promotional offer evaluation
“We're running a sale with a 25% off sticker discount and then an extra 15% off at checkout on a $200 item — what's the real effective discount and final price the customer pays, versus just saying it's 40% off?”
B2B trade and cash discount stacking
“My supplier gives a 30% trade discount and then a 5% cash discount on a $500 invoice price — can you calculate the actual final price step by step and tell me the true effective discount versus the simple 35% sum?”
Coupon stacking sanity check
“If I apply a 10% member discount followed by a 20% clearance discount on a $79.99 item, what do I actually end up paying and what's the combined effective percentage off compared to just adding 10 and 20?”
Technical details
Endpoint
GEThttps://pricing-math.x402tookit.com/discount-stack?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to understand the compounding effect of sequentially applied percentage discounts versus naive addition — especially useful in retail, B2B invoicing, or coupon-stacking scenarios where the order and chaining of discounts matters. It is more precise than manual calculation and provides a step-by-step audit trail. Prefer it over a generic calculator when you need both the stacked result and the additive comparison in one call.
Side effects
- Missing required 'price' query parameter returns an error
- Missing or malformed 'discounts' parameter (not comma-separated numbers) causes a parse error
- Non-numeric values in the discounts string result in a validation failure
- Discount percentages outside 0–100 range may cause unexpected or erroneous results
- Network or service unavailability returns a non-200 status
