What Is a Discount Calculation?
A discount calculation finds the amount payable after a reduction is applied to a product's list (sticker) price, along with the money saved. This tool works both ways: if you have the discount percentage it computes the sale price; if you have the discounted price directly it back-calculates the effective discount rate. An optional VAT setting adds 1%, 10% or 20% tax on top of the discounted amount, so you can also see the VAT-inclusive price the customer pays at the till.
Two Modes
- Percentage off: enter the list price and the discount rate (%). The tool computes the sale price (list × (1 − rate/100)) and the savings. For example a 1,000 ₺ item at 20% off → 800 ₺ sale price, 200 ₺ saved.
- Discounted price: enter the list price and the discounted sale price directly. The tool reports the difference as savings and its ratio to the list price as the effective discount — answering "what percentage off is this price, really?".
How to Use It
- Enter the list price: the undiscounted sticker price.
- Choose the discount type: pick percentage or discounted price and fill the relevant field.
- Set VAT (optional): choose a rate to include tax, or leave "No VAT" selected.
- Click Calculate: sale price, savings, discount rate and any VAT-inclusive total appear instantly.
Who Is It For?
- E-commerce and retail: check whether a campaign price still protects your margin. To build a store or add campaign logic to an existing one, our e-commerce solutions service can help.
- Shoppers: see what a "30% off" tag is worth in money and what you will actually pay.
- Sales teams: quickly find the percentage a negotiated price corresponds to and keep quotes consistent.
- Accounting: add VAT on the discounted amount to verify an invoice total in advance.
Tips and Common Mistakes
- VAT before or after the discount? This tool adds VAT on the discounted amount, the standard retail practice.
- Successive discounts don't add up: "20% + 10% off" is not 30%; the second discount applies to the amount after the first. Use the tool in two steps for the correct figure.
- Sale price can't exceed the list price: if you enter a discounted price higher than the list price, savings are treated as zero.
Discounts, Margin and Pricing
Discounts speed up sales but hit your margin directly, so the rate should be set with your cost in mind. For an item costing 600 ₺ and listed at 1,000 ₺, a 20% discount drops the sale price to 800 ₺ and your gross profit from 400 ₺ to 200 ₺. Once the discount exceeds your cost margin you start selling at a loss; use this tool to check in advance whether the discounted price falls below your cost.
In psychological pricing, a discount works through the anchor effect: the customer sees the high list price first, then perceives the discounted amount as a "saving". Showing list price, savings and sale price together therefore lifts conversion. When planning a campaign, answer three questions with this tool: what is the sale price, how much will the customer feel they saved, and what will they pay at the till with VAT? Building seasonal campaigns, cart discounts or a coupon system into your store requires discount rules that stay consistent with stock and margin.
