Tip Calculator
A tip calculator is a dining utility that computes exact gratuity amounts and divides the final restaurant bill evenly among diners. Using the formula Tip = Bill × (Tip% / 100), it quickly calculates customary gratuity rates like 15%, 18%, or 20%, showing that a 20% tip on $50 equals $10.
