Calculate the final price after a percentage or fixed-amount discount and the money saved — and, for a fixed amount, the effective discount rate. Useful for pricing promotions, supplier negotiations, and validating discounted invoices.
Discounts run the entire MENA retail and B2B economy. A Riyadh trader negotiates a 12% volume discount on a container of imported electronics; a Cairo coffee shop runs a 'buy two, get one free' weekend promotion; a Dubai SaaS founder offers an annual prepay 20% off the monthly rate; a Jeddah construction supplier hands out a 5% early-payment discount on every invoice over SAR 50,000. The Xuvilo discount calculator works out any single discount like these instantly. It takes plain numbers, so the answer is in whatever currency you priced in.
Enter the discount either as a percentage or as a fixed amount off, and the calculator shows the final price and the amount saved. For a fixed amount it also shows the effective discount rate — so a flat “30 off” and a “15% off” can be compared on the same footing.
It pairs naturally with the Xuvilo invoice generator and quotation generator: work out the offer here, then enter the price and the discount on the line in a full quote or invoice. The discount appears as its own row on the PDF for transparency — exactly what corporate procurement teams expect.
Discount Amount = Original Price × Discount % ÷ 100
Final Price = Original Price − Discount Amount
Effective Discount % = Discount Amount ÷ Original Price × 100 (fixed amount)
$200 with a 15% discount → discount $30 → final price $170. A fixed $30 off $200 is an effective 15% discount.
Divide the discount amount by the original price and multiply by 100. Example: ($30 ÷ $200) × 100 = a 15% discount.
Multiply the original price by (1 − discount % ÷ 100). Example: $200 at 15% off = $200 × 0.85 = a final price of $170.
A percentage discount (such as 20% off) grows with the price, so it saves more on expensive items. A fixed discount (such as $20 off) saves the same amount whatever the price. Percentage discounts are more common in retail and fixed ones in wholesale deals. The calculator's effective rate puts the two on the same footing: 30 off a price of 200 is the same as 15% off.
They multiply rather than add. A 20% discount followed by 10% leaves 0.80 × 0.90 = 72% of the price — a combined 28% discount, not 30% — and two 10% discounts make 19%, not 20%. To stack discounts here, run the calculator twice, using the first final price as the second original price.
Before. VAT is charged on the price after the discount, so a SAR 1,000 item with a 10% discount and 15% VAT becomes SAR 900 before VAT and SAR 1,035 with it. Xuvilo's invoice generator works in that order: it takes each line's discount off first and charges VAT on what is left.
Generally, yes. UAE tax invoices must show the amount of any discount, and Saudi tax invoices must show discounts not already deducted from the unit price; either way, VAT is worked out on the price after the discount. Xuvilo's invoice generator shows the discount total as its own line in the totals.
A trade discount is taken off the list price before the invoice is issued, usually for business buyers or bulk orders. A cash discount is an incentive to pay early, offered on the invoice itself — the next question shows what it costs.
A common B2B term is '2/10 net 30': 2% off if the invoice is paid within 10 days, otherwise the full amount within 30. It costs more than it looks: a customer who pays 20 days early to save 2% earns about 37% a year on that money, (2 ÷ 98) × (365 ÷ 20). Offer it when getting paid sooner is worth that much to your cash flow.
After computing the discount, send the quote with the free Xuvilo quotation generator or invoice the customer with the free invoice generator — both take a percentage discount on each line. For more pricing and invoicing guides, head to the Xuvilo Blog.
