View monthly and annual fixed costs instantly. Compare ratios, per-unit impact, and break-even support confidently. Use clearer numbers to control recurring expenses with confidence.
Use monthly figures for all expense categories. Optional operating inputs help calculate ratios, unit cost, break-even units, and reserve runway.
This example uses monthly amounts to demonstrate how the calculator converts recurring fixed expenses into ratios, annual totals, and break-even outputs.
| Input / Output | Example Value | Notes |
|---|---|---|
| Monthly Revenue | $24,000.00 | Used for fixed expense ratio and coverage. |
| Expected Units Sold | 1,800 | Used for fixed expense per unit. |
| Contribution Margin per Unit | $12.00 | Used for break-even unit estimate. |
| Cash Reserve | $30,000.00 | Used for reserve runway months. |
| Rent / Lease | $3,200.00 | Main location rent. |
| Salaries / Benefits | $5,000.00 | Recurring payroll burden. |
| Insurance | $650.00 | Business insurance cost. |
| Subscriptions / Software | $420.00 | Platforms and software tools. |
| Loan Payments | $1,000.00 | Recurring financing commitment. |
| Depreciation | $500.00 | Monthly non-cash fixed allocation. |
| Fixed Utilities | $430.00 | Base utility commitment. |
| Administrative Overhead | $350.00 | Office and support costs. |
| Other Fixed Costs | $250.00 | Miscellaneous recurring fixed items. |
| Total Monthly Fixed Expense | $11,800.00 | Sum of all fixed categories. |
| Fixed Expense Ratio | 49.17% | $11,800 ÷ $24,000 × 100. |
| Fixed Expense per Unit | $6.56 | $11,800 ÷ 1,800 units. |
| Break-even Units | 983.33 | $11,800 ÷ $12.00 contribution margin. |
Contribution margin per unit means selling price per unit minus variable cost per unit.
A fixed expense is a recurring cost that usually stays stable over time, regardless of short-term sales volume. Rent, insurance, salaries, subscriptions, and scheduled loan payments are common examples.
Enter monthly values for every cost category. The calculator automatically converts the total into quarterly and annual fixed expense projections for easier planning.
It shows how much of your revenue is consumed by fixed costs before variable expenses and profit. A high ratio means less operating flexibility.
Contribution margin per unit equals selling price per unit minus variable cost per unit. It helps estimate how many units are needed to cover fixed expenses.
Yes. If you provide contribution margin per unit, the calculator estimates break-even units. That gives a quick view of the sales volume needed to absorb monthly fixed costs.
Reserve runway estimates how many months your current cash reserve can support fixed expenses. It is useful for budgeting risk, scenario planning, and liquidity discussions.
Dashes appear when an optional field is missing or zero. For example, break-even units need contribution margin, and fixed expense per unit needs expected unit volume.
Yes. You can treat rent, insurance, subscriptions, and debt payments as fixed personal costs. The same logic helps measure stability and recurring budget pressure.
