Frequently Asked Questions - Percentage Calculator
To find what percentage X is of Y, use the formula: (X ÷ Y) × 100. For example, to find what percentage 25 is of 100: (25 ÷ 100) × 100 = 25%. Select "What Percent" in the calculator and enter your values to get instant results.
Markup is the percentage added to cost price to get selling price. Margin is the percentage of selling price that represents profit. Example: Cost $100, Markup 30% = Selling price $130. The margin would be 23.08% (profit $30 ÷ selling price $130). Our calculator shows both values.
Percentage change formula: ((New Value - Original Value) ÷ Original Value) × 100. Positive results indicate increase, negative indicate decrease. Example: Price went from $100 to $120: ((120-100) ÷ 100) × 100 = 20% increase. Use our "Percentage Change" option for automatic calculations.
Standard tipping guidelines: Poor service (10%), Average service (15%), Good service (18%), Excellent service (20%), Outstanding service (25%). Our tip calculator includes these presets, but you can also enter custom percentages. Remember to consider local customs and service quality.
