This Fixed Cost Planning Calculator helps financial planners and entrepreneurs determine the maximum allowable fixed expenditure (F) given their pricing, variable costs, and sales volume targets.
The **Fixed Cost Planning Calculator** utilizes the Cost-Volume-Profit (CVP) analysis framework to solve for the total funding requirement (F), which encompasses both Fixed Costs and any desired Target Profit. This ensures that the chosen cost structure is financially sustainable for the business model.

Detailed Calculation Steps
Fixed Cost Planning Formula
The core calculation for Fixed Costs and Target Profit (F) is the foundation of CVP analysis, determining the required revenue needed above variable costs.
Formula to Solve for Fixed Costs & Target Profit (F)
F = Q × (P – V)
Formula to Solve for Sales Volume (Q)
Q = F / (P – V)
Formula to Solve for Selling Price (P)
P = V + (F / Q)
Formula to Solve for Variable Cost (V)
V = P – (F / Q)

Variables Explained
The calculation relies on the relationship between four key financial variables:
- **F (Fixed Costs & Target Profit):** This is the output when solving for F, representing the total maximum fixed expenditure (including rent, salaries, utilities) the company can sustain while achieving its target profit at the given sales levels.
- **P (Selling Price Per Unit):** The revenue generated from selling one unit of the product.
- **V (Variable Cost Per Unit):** Costs that change directly in proportion to the volume of output (e.g., raw materials).
- **Q (Sales Volume):** The projected or actual number of units sold over the period.

What is the Fixed Cost Planning Calculator?
The Fixed Cost Planning Calculator is a crucial managerial accounting tool used for budgeting and long-term strategy. Its core purpose is to validate if a business’s current or proposed cost structure (Fixed Costs) aligns with its revenue expectations (Price and Volume) and profit goals. By determining the total required funds (F) generated by the sales activity, managers can budget for rent, salaries, and other overheads without jeopardizing profitability.
If the calculation reveals that the allowable fixed costs are lower than the company’s current fixed expenses, management knows they must either reduce overhead, increase the price (P), or increase sales volume (Q) to achieve the target profit. This proactive analysis prevents financial strain and guides strategic cost control efforts.
How to Calculate Fixed Costs & Target Profit (Example)
Here is a step-by-step example of how the calculation works when solving for Required Funds (F):
- **Input Selling Price and Variable Cost (P & V):** The unit price (P) is $100, and the Variable Cost (V) is $40.
- **Determine Sales Volume (Q):** The projected sales volume (Q) is 2,500 units.
- **Calculate Contribution Margin:** CM = P – V = $100 – $40 = $60 per unit.
- **Apply the Formula:** F = Q × CM. F = 2,500 × $60.
- **Find the Required Funds (F):** F = $150,000. This is the maximum amount the company can allocate to Fixed Costs plus Target Profit and remain financially healthy under the current projections. If actual Fixed Costs are $120,000, the remaining $30,000 is the achievable profit.
Frequently Asked Questions (FAQ)
Is the output (F) only Fixed Costs?
No. The output (F) represents the total amount of money generated by the contribution margin that is available to cover all Fixed Costs AND any desired Target Profit. If you want to know the maximum purely Fixed Costs you can afford, set your desired Target Profit to zero before calculating.
How does this calculation handle operating leverage?
Fixed costs are directly related to operating leverage. A higher calculated F (relative to total costs) indicates a higher degree of operating leverage, meaning a small change in sales volume (Q) will result in a larger change in profit.
What if the Contribution Margin (P – V) is negative?
If P < V, the Contribution Margin is negative, and the calculated required funds (F) will also be negative. This means every unit sold *loses* money, and the business model is unsustainable, regardless of volume (Q).
Can I use this to budget for future years?
Yes. This tool is excellent for “what-if” scenarios. By projecting increases in Price (P) and Variable Cost (V), and anticipating sales changes (Q), you can use the resulting F to set an informed budget ceiling for your next fiscal year’s fixed expenditures.
