Here Are the Steps to Forecast Variable and Fixed Costs Easily

To skip all these steps, you can simply download a financial forecast tailored to your industry.

  • 1. Identify Your Fixed Costs:

    Start by listing all the expenses that will remain constant regardless of the number of customers. These might include rent for office space, salaries for full-time employees, and subscriptions for essential software tools. For example, if you plan to rent an office space and hire two employees, calculate the total monthly cost for these fixed expenses.

  • 2. Estimate Your Variable Costs:

    Next, determine the costs that will fluctuate based on the number of customers. These could include expenses for digital resources, customer support, and other per-customer costs. Estimate the cost per customer and multiply it by the projected number of customers for the first month.

  • 3. Calculate Total Monthly Costs:

    Add your fixed costs and variable costs to get the total monthly expenses. This will give you a clear picture of your financial requirements for the first month of operation.

  • 4. Use Simple Calculations:

    By breaking down your costs into fixed and variable categories and using straightforward calculations, you can easily forecast your expenses. This methodical approach helps you avoid feeling overwhelmed and provides a clear financial picture.

  • 5. Plan Effectively:

    With a clear understanding of your costs, you can make informed decisions and plan effectively for your business launch. This will help you manage your finances better and ensure a smoother start for your business.

A Practical Example for Better Understanding

This is a simplified example to illustrate the process. For a more reliable estimate without having to calculate, access one of our financial forecasts tailored to 200 different business types.

To help you better understand, let's use a made-up example of a startup planning to launch an online subscription service for fitness coaching.

First, identify your fixed costs, which are expenses that remain constant regardless of the number of customers. These might include rent for a small office space at $1,000 per month, salaries for two full-time employees at $3,000 each per month, and software subscriptions for essential tools at $500 per month. Therefore, your total fixed costs amount to $7,500 per month.

Next, estimate your variable costs, which fluctuate based on the number of customers. Suppose you anticipate that each customer will require $10 worth of digital resources and $5 for customer support per month. If you project acquiring 200 customers in the first month, your variable costs would be 200 customers * ($10 + $5) = $3,000.

To forecast your total costs, simply add your fixed and variable costs: $7,500 (fixed) + $3,000 (variable) = $10,500 for the first month.

By breaking down your costs into these categories and using straightforward calculations, you can easily forecast your expenses without feeling overwhelmed. This methodical approach provides a clear financial picture, helping you make informed decisions and plan effectively for your business launch.
