1. How to Calculate a Percentage Discount (ছাড়ের সাধারণ নিয়ম)
The standard mathematical formula to calculate the final sale price after a percentage discount is:
Real-World Example (বাস্তব উদাহরণ):
- Item: Branded Sneakers / জুতো
- Original Price: $120 (বা ৳১,২০০)
- Discount Offer: 25% Off
- Savings Calculation:
$120 × (25 / 100) = $30(বা ৳৩০০ সাশ্রয়) - Final Sale Price:
$120 - $30 = $90(বা ৳৯০০ পরিশোধ করতে হবে)
2. How Stacked / Double Discounts Work (ডাবল কুপন ছাড়ের আসল রহস্য)
A common mistake shoppers make is adding multiple discount percentages together. For example, if a store offers 30% off clearance items and an extra 20% off coupon code, the total discount is NOT 50%!
In retail, sequential / stacked discounts are applied consecutively to the remaining discounted balance:
| Step | Calculation | Remaining Price | Savings in Step |
|---|---|---|---|
| Original Price | Starting retail price | $100.00 | - |
| 1st Discount (30% Off) | $100 × 0.30 |
$70.00 | $30.00 |
| 2nd Discount (20% Extra Coupon) | $70 × 0.20 |
$56.00 | $14.00 |
| True Compound Result | Total paid: $56.00 | Total Saved: $44.00 (44% Effective Discount, NOT 50%) | |
Our calculator automatically computes sequential stacked discounts so you never get misled by deceptive retail math.
3. Calculating Sales Tax or VAT with Discounts
In most regions and online platforms, Sales Tax or VAT is calculated on the discounted price (the actual money you spend), not the original price:
Total Amount Payable = Discounted Price + Sales Tax Amount
Example: If an item is discounted down to $80 and your local sales tax is 5%, you pay $80 + ($80 × 0.05) = $80 + $4 = $84.
4. Buy X, Get Y Free (BOGO Deals Explained)
Retailers frequently advertise promotional offers like "Buy 2, Get 1 Free" or "Buy 1, Get 1 at 50% Off". Here is the true discount breakdown for popular BOGO offers:
| Promotional Offer | Total Items Received | Equivalent Free Items | True Effective Discount |
|---|---|---|---|
| Buy 1, Get 1 Free (BOGO) | 2 Items | 1 Free | 50.0% Off |
| Buy 2, Get 1 Free | 3 Items | 1 Free | 33.33% Off |
| Buy 3, Get 1 Free | 4 Items | 1 Free | 25.0% Off |
| Buy 1, Get 1 at 50% Off | 2 Items | 0.5 Free | 25.0% Off |
5. Reverse Discount: Finding the Original Sticker Price
If you bought an item on sale and only know the final price paid along with the discount percentage, you can quickly find the original retail price using the reverse formula:
Example: If you paid $75 after receiving a 25% discount, the original retail price was: $75 ÷ (1 - 0.25) = $75 ÷ 0.75 = $100.00.
