Tip Calculator Examples
The Tip Calculator calculates tip amounts and total bills for restaurant dining, service payments, and group bill splitting. Below are practical examples for different tip percentages, group sizes, and service contexts.
Basic Tip Calculation
// Formula:
// Tip amount = Bill × (Tip% / 100)
// Total = Bill + Tip amount
// Example: $45.00 bill at 20% tip
Bill: $45.00
Tip (20%): $9.00
Total: $54.00
// Example: $78.50 bill at 18% tip
Bill: $78.50
Tip (18%): $14.13
Total: $92.63
// Example: $120.00 bill at 25% tip (excellent service)
Bill: $120.00
Tip (25%): $30.00
Total: $150.00

}
calculateTip(80, 20, 4);
// { bill: "80.00", tip: "16.00", total: "96.00", perPerson: "24.00", tipPercent: 20 }
