Frequently Asked Questions

How do I calculate percent of a number?

Multiply the number by the percentage as a decimal. For 25% of 80: 80 × 0.25 = 20. Or use our calculator: enter 25 in 'What is X%' and 80 in 'of Y'.

What's the difference between percentage change and percentage difference?

Change measures increase/decrease from a starting value. Difference compares two values without declaring one as the 'original'. Use change for growth rates, difference for comparisons.

US: 15-20% for restaurants, 18-20% for excellent service. Bars: $1-2 per drink or 15-20%. Delivery: 15-20% or $3-5 minimum. Hairstylists: 15-20%. Adjust based on location and service quality.
