## GM Income Calculator

### How to Use the Calculator

Enter your monthly sales amount in dollars and your gross margin percentage in the fields provided, then click the “Calculate” button to see your gross margin income.

### How It Calculates Results

The calculator multiplies your monthly sales by your gross margin percentage (divided by 100 to convert from a percentage to a decimal) to give you your gross margin income.

### Limitations

This calculator strictly computes gross margin income based on the input values provided. It doesn’t account for taxes, operational costs, or other expenses that may reduce your actual take-home amount. Additionally, it assumes the percentage provided is a gross margin percentage, not a markup percentage or net margin percentage.
