Where 18% Shows Up in Real Life
🍷
Standard "good service" tip in the US. 18% has become the new baseline at many restaurants, especially for parties of 6+.
Example: 18% off $100 = $18. On a $100 dinner bill, 18% tip = $18. Many restaurants auto-add 18% gratuity for large parties.
Pro Tip
Quick 18% tip math: find 20% (move decimal, double) then subtract a small amount. 20% of $85 = $17, so 18% ≈ $15.30.
How to Calculate 18% Off Any Price — Step by Step
1
Convert to Decimal
18% ÷ 100 = 0.18
2
Find the Discount
Price × 0.18 = Savings
3
Get the Final Price
Price − Savings = Final Price
$100 → $100 × 0.18 = $18.00 discount → $100 − $18.00 = $82.00
Shortcut: multiply the price by 0.82 to get the final price directly.
Quick Trick: 18% Off in Your Head
Find 20%, then subtract 2%.
$80 → 20% = $16, 2% = $1.60 → subtract → $14.40 off → you pay $65.60
18% = 20% − 2%. Break it into parts you can do in your head.
