The Fixed Cost Per Month Calculator is a practical tool that helps individuals and business owners determine their recurring monthly expenses that do not change with production levels or sales volume. These are known as fixed costs and typically include rent, insurance, employee salaries, subscriptions, and other contractual payments.
This calculator simplifies financial planning by converting all relevant costs, even those billed quarterly or annually, into a clear and standardized monthly format. It ensures better budget management, cash flow analysis, and helps evaluate operational stability over time.
formula of Fixed Cost Per Month Calculator
Fixed Cost Per Month = Total Annual Fixed Cost / 12
Alternatively, when fixed costs are entered individually by billing cycle:
Fixed Cost Per Month = Sum of All Monthly Fixed Costs
If some costs are billed periodically (e.g., quarterly, annually), convert them into monthly equivalents:
Monthly Equivalent = Cost Amount / Number of Months in Billing Cycle
Final calculation:
Fixed Cost Per Month = Sum of [Monthly Costs + Monthly Equivalent Costs]
Where:
Total Annual Fixed Cost = Total fixed expenses incurred across 12 months
Monthly Fixed Costs = Expenses that occur regularly every month
Monthly Equivalent = Pro-rated cost from quarterly, semi-annual, or annual payments
Fixed Cost Reference Table

Example of Fixed Cost Per Month Calculator
Let’s say a small business incurs the following annual and monthly fixed costs:
- Rent: $1,500/month
- Insurance: $1,200/year
- Software License: $300/year
- Equipment Lease: $900/quarter
- Salaries: $3,000/month
Step 1: Convert all to monthly equivalents
- Insurance: $1,200 / 12 = $100
- Software License: $300 / 12 = $25
- Equipment Lease: $900 / 3 = $300
Step 2: Add all monthly costs
Fixed Cost Per Month = $1,500 + $100 + $25 + $300 + $3,000 = $4,925
So, the total fixed cost per month is $4,925.
