Calculate discounts and sale prices instantly
Free online discount calculator to quickly find the final price after a discount. Supports two modes: calculate by percentage (%) or by fixed amount ($). Quick buttons for 10 common discount levels (5% to 70%). Shows original price with strikethrough, savings amount in red, and final price in green. Real-time calculation as you type. Works with any currency.
When shopping online with countless promotions, calculating the actual price can be confusing. Is 30% off better than $30 off? How much do you actually save? This tool answers these questions instantly. It's useful for comparing deals from different stores, calculating the final price before checkout, understanding how much you save on sale items, and deciding whether a discount is worth it.
Which is better — 30% off or $30 off? It depends on the original price. The break-even point is $100. Below $100: fixed amount ($30 off) saves more. Above $100: percentage (30% off) saves more. At exactly $100: both save the same. For example, on a $50 item: 30% off saves $15, but $30 off saves $30. On a $200 item: 30% off saves $60, but $30 off saves only $30.
It depends on the original price. If original price × 30% > $30, then 30% off is better. The break-even point is $100. Below $100: fixed amount is better. Above $100: percentage is better.
The tool calculates one discount at a time. For stacked discounts: Step 1 — enter original price, calculate first discount, note the final price. Step 2 — enter that final price as the new original price, apply the second discount. Note: 20% + 10% ≠ 30%.
The display uses USD formatting, but the math works for any currency. Simply enter your price in your local currency and interpret the result accordingly.
If you know the final price and the discount percentage, the original price = final price ÷ (1 - discount%). For example, $80 after 20% off means original = $80 ÷ 0.8 = $100.
This tool focuses on discounts only. To add tax, take the final discounted price and multiply by (1 + tax rate). For example, $80 with 10% tax = $80 × 1.10 = $88.
