A small price makes rounding visible
At $19.99 with 15% off, exact savings are $2.9985. Round savings first to $3.00, then subtract to show $16.99. At $0.05 with 10% off, savings are $0.01 and final price is $0.04. The entered percentage is not a recalculated effective rate.

Questions, answered.
How is a percentage discount rounded?
Savings are calculated exactly from original cents and the requested percentage, rounded half-up to cents, then subtracted from original cents. The final price and savings therefore add back to the original price.
Can a fixed discount exceed the original price?
No. The calculator rejects a fixed reduction above the original price instead of clamping the result. A reduction equal to the original price is valid and leaves zero.
Does this calculate BOGO, taxes or shipping?
No. It handles one percentage or fixed reduction on one original price. BOGO, tax, shipping, stacked discounts and checkout cart allocation are outside its scope.
