1. What is the Estimate Tips Formula?

The Estimate Tips formula calculates the expected tip amount based on the total sales and the desired tip percentage. It's commonly used in service industries to predict earnings or help customers determine appropriate gratuity.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Sales \) — Total sales amount in USD
• \( Tip Rate \) — Desired tip percentage (e.g., 15% = 15)

Explanation: The formula multiplies the total sales amount by the tip rate (converted from percentage to decimal) to calculate the tip amount.

3. Importance of Tip Estimation

Details: Estimating tips helps service workers predict earnings, allows customers to budget appropriately, and ensures fair compensation for services rendered.

4. Using the Calculator

Tips: Enter the total sales amount in USD and the desired tip percentage. Both values must be valid (sales > 0, tip rate ≥ 0).
