Formula Used in Operating Expense Calculator

Example Calculation
Let’s say you are running a mid-sized business and want to calculate your monthly operating expenses. Here’s a breakdown of your costs:
- Salaries: $25,000
- Commissions: $5,000
- Advertising Cost: $3,000
- Rental Costs: $4,500
- Utility Costs: $2,000
Using the formula:
Operating Expense = 25,000 + 5,000 + 3,000 + 4,500 + 2,000
Operating Expense = $39,500
The calculator will instantly display:
Operating Expense: $39,500.00
