How Discounts Work
A discount reduces the original price by a percentage. The formula is simple: Final Price = Original Price × (1 - Discount%/100). For example, a 25% discount on a Rp1,200,000 item: Rp1,200,000 × 0.75 = Rp900,000.
When multiple discounts are applied (stacked), they are calculated sequentially, not added together. A 20% + 10% discount is NOT 30% off — it is 20% off first, then 10% off the reduced price, equaling 28% total.
Shopping Tips
Smart shopping strategies:
- Calculate price per unit to compare differently sized packages
- Check if sale price beats generic brands — sometimes the regular price of a store brand is lower than the discounted name brand
- Use the Rule of 100: For items under Rp1,500,000 percentage discounts feel bigger; for items over Rp1,500,000 dollar amounts feel bigger

Frequently Asked Questions
How do I calculate the original price from a sale price?
Divide the sale price by (1 - discount/100). Example: An item is Rp630,000 after a 30% discount. Original = Rp630,000 / 0.70 = Rp900,000.
Is it better to get a coupon or a percentage off?
Compare the actual savings. A Rp150,000 coupon on a Rp600,000 item (25% off) is better than a 20% discount (Rp120,000 off), but worse than a 30% discount (Rp180,000 off).
Do stacked discounts save more than a single equivalent discount?
No. Two successive discounts of 20% and 10% equal 28% off total, not 30%. A single 30% discount saves you slightly more.
