Currency changes formatting only, not exchange rates. Calculations keep precision until display; a real receipt may differ because of rounding rules.
Build your purchase
Enter the applicable tax rate yourself. Tax is calculated on discounted merchandise. Shipping has its own tax setting. This is a configurable estimate, not country-specific tax advice.
Apply discounts in order
Discounts apply in order to the remaining merchandise total. A fixed coupon is for the entire merchandise line, not for each item. Delivery is not discounted.
Your price breakdown
How much of the merchandise price do you save?
This bar compares merchandise savings with the original merchandise price. Delivery is excluded.
From original price to checkout total
- Original merchandise before tax
- Discount on the entered price basis
- Tax on merchandise
- Shipping before tax
- Tax on shipping
- Total to pay
The chart starts with merchandise before tax, subtracts the net discount, then adds merchandise tax, shipping and shipping tax.

What would other discounts save?
This table replaces the main coupons with a single discount. It keeps the main price, quantity, tax and shipping settings.
Work backwards from the final price
All final-price fields below include merchandise tax and delivery. These blocks share the reverse-calculation settings, but are independent of the main purchase above.

Find the original price
Find the discount needed for a target price
The target percentage is rounded up to two decimal places so the modelled total does not exceed the budget. Delivery and its tax are unchanged.
Compare two offers
Each offer has one merchandise coupon and its own price, quantity, tax and shipping settings. Compare equal quantities for a like-for-like total, or use the per-item result.

Offer B

Successive discounts multiply
Understand discounts without surprises
Successive percentage discounts multiply the price remaining; they do not add. A 20% sale followed by a 10% coupon leaves 72% of the original merchandise price, so the combined discount is 28%. An unchanged delivery charge reduces the saving as a percentage of the entire bill. Always check coupon eligibility and the store’s actual tax and rounding rules.
Discount calculator questions
Are two discounts added together?
No. Each discount applies to the amount left by the previous one. For example, 20% followed by 10% is a combined 28% merchandise discount.
Does a fixed coupon apply to every item?
In this calculator, a fixed coupon applies once to the entire merchandise line. Quantity multiplies the original item price before the coupons are applied.
How does the tax-included option work?
The entered tax-included price is divided by one plus the tax rate to find the amount before tax. Tax is then shown separately without being charged twice.
Can shipping also be taxed?
Yes, if you select the shipping-tax option. The shipping input is always before tax. Delivery is not reduced by merchandise discounts.
Why can a receipt differ slightly?
The calculator retains precision internally and rounds displayed amounts. Stores may round each item, coupon or tax line separately, and their coupon rules may differ.
Can the calculator recover a price after a 100% discount?
No unique original price can be recovered from a fully discounted merchandise price. The forward calculator can still apply a 100% merchandise discount; delivery may remain payable.
