What Is the Fixed Expenses Formula?

I’m trying to better understand my business’s cost structure and keep seeing references to the fixed expenses formula. I know fixed costs don’t change with sales volume, but I'm not fully sure how to calculate them properly or what should be included. Can someone explain the fixed expenses formula in simple terms? Also, how do I differentiate fixed expenses from variable expenses when preparing financial statements? Any practical examples or tips for accuracy would be really helpful!
 
Fixed expenses are costs that stay the same regardless of your sales, like rent, salaries, or insurance. The formula is simple: Fixed Expenses = Total of all fixed costs. To separate them from variable expenses, look for costs that don’t change with production or sales. For example, monthly office rent stays the same whether you sell 10 or 1,000 products, while materials cost would be variable.
 
The fixed expenses formula helps calculate total costs that do not change with production or activity level. It is:
Fixed Expenses = Rent + Salaries + Insurance + Utilities + Other Fixed Costs

These expenses stay constant regardless of business output or sales.
 
The most common formula to determine Total Fixed Expenses (FC) is by separating them from the Total Costs (TC) of a business:

FC = TC - Total Variable Costs (VC)
Total Variable Costs (VC) are calculated as:

VC = {Variable Cost Per Unit}) x {Number of Units Produced}
 
Fixed expenses formula:
Total Fixed Expenses = Sum of all recurring, regular costs that don’t change with activity levels (e.g., rent, insurance, salaries).
Use it to calculate monthly or annual fixed financial obligations.
