🧐 Frequently Asked Questions

Does the order of discounts matter? Yes. Taking 10% off a $100 item and then subtracting $10 results in $80. Subtracting $10 first and then taking 10% off results in $81. Use the "Calculation Order" setting to ensure your math matches the retailer’s system.

How is rounding handled? The tool rounds to the nearest cent to mirror standard retail accounting and POS systems.

Can I use this for sales tax only? Absolutely. Set your discounts to zero and adjust the tax rate to see the final price of any item.

📚 The Psychology of "Double Discounts"

Retailers often advertise "20% OFF + 10% OFF" instead of "28% OFF." Why? Because the human brain instinctively adds the numbers (20+10=30), making the deal feel larger than it actually is. This is known as the "double-couponing effect." While 28% is still a great deal, this tool ensures you see the real math before you reach the register. 💸
