Importance of Forecasting Expenses and Income

Company finances are important and also somewhat complicated. Having a forecast of expenses and income is essential to draw up the strategy to follow and subsequently check for deviations.

What is Income and Revenue Projection?

The Revenue Projection and income is a budget projection of a company’s financial resources. On the one hand, the income it will receive and on the other, the expenses it must face. It is vital to distinguish between an accounting expense and the actual payment. Forecasting should focus on cash flow, recording the exact moment money leaves the account rather than just when the invoice is received, ensuring that funds are always available.

This process is very important for the company’s financial stability and decision-making.

Company Revenue Projection

To make an income forecast, you must estimate the financial resources you expect to obtain from sales, investments and any other source of income.

Accurate revenue forecasting requires analysis of historical data, market trends and economic conditions.

Company Expense Revenue Projection

Expense forecasting is done by calculating all the payments that the company will have to make in a period of time. Payments include fixed costs, variable costs and one-time costs:

Fixed costs. These are expenses that are stable over time. The most common examples are rent and service subscriptions.
Variable costs. These are expenses that, although recurring, change depending on different factors. Some examples of these types of expenses are water, electricity or gas, and material costs. Nonetheless, while utilities such as water, electricity, or gas are often categorized as variable, in many service-based companies, they act as fixed or mixed costs due to minimum service fees. It is also advisable to include sales commissions or shipping and logistics costs, as these expenses scale in direct proportion to revenue volume and business activity.
One-time costs. These are expenses that the company faces less frequently. Examples include the purchase of equipment and facilities. When identifying these costs, it is essential to consider depreciation. From an accounting perspective, this allows the impact of a major investment to be spread over its useful lifetime, providing a more realistic view of costs in long-term planning.

Importance of Revenue and Expense Forecasting

It is very important for a company to make a forecast of income and expenses for the following reasons:

Cash flow is better controlled. This allows for a forecast of a lack or excess of liquidity and helps in making decisions about investments or available funds.
Set spending limits. You should set a limit on the spending you can afford, prioritizing based on needs, locating leaks and detecting strong points.
Optimize resources. Knowing the company’s future income allows expenses to be adjusted and resources to be allocated efficiently.
Anticipate financing needs. By having accurate forecasts, the company will have the information when it needs internal or external financing to cover unforeseen expenses.
Review and modify budgets. When budgets are made, they must be realistic and flexible, allowing for changes based on the company’s monthly situation.

How to Make an Income and Revenue Projection

When making a forecast of income and expenses, there are a few steps to follow to ensure that it is as close to reality as possible.

Collect Information

Obtaining all possible data from previous periods provides a solid basis for makingfuture predictions.

One way to obtain this information is to use the software that the company uses for its accounts. For a more robust foundation, companies can utilize ERP systems, advanced Excel, or Business Intelligence (BI) tools, which facilitate real-time traceability and agile adjustments to forecasts.

Analyze Market Trends

Knowing how the market is performing and the economic situation and trends is essential.

Spending and income can be affected by seasonality, changes in the market and consumer behavior. The analysis should not be linear; it must identify seasonal peaks and troughs. For instance, considering utility cost increases in winter or sales spikes during specific periods, avoiding the mistake of simply dividing the annual budget by twelve months.

Make a Forecast of Future Income

Considering data from previous periods and market trends that have been analyzed, an estimate can be made of the income that will be received.

It is important to make the forecast in a realistic way and evaluate different scenarios, from the most optimistic to the most pessimistic, to be able to prepare the company for any situation. When evaluating scenarios, it is advisable to apply the prudence principle: in case of uncertainty, it is better to slightly underestimate projected income and overestimate expenses. This serves as a safety buffer to protect liquidity against unforeseen events.

Identity and Forecast Expenses

When making an expense forecast, all costs related to the operation of the company must be included. They are divided, as we have seen in previous sections, into fixed costs, variable costs and one-time costs.

With this identification it is possible to establish a spending limit that reflects the financial status of the company.

Expense Segmentation

Each department in the company must have its own expense allocation. This distribution must be made in relation to the sales strategy to ensure the profitability of the business.

Monitoring and Modification

Even if the income and expenditure forecast has been made, it is important to review it from time to time. This is because there are situations that can change and the forecasts must be adjusted to the actual results and new expectations to ensure financial stability.

For forecasting to be a truly professional management tool, it is not enough to make an initial estimate. It is essential to perform a variance analysis at the end of each month, comparing projected data with actual results. Calculating this margin of error allows you to identify why expectations were not met and adjust future projections to make them increasingly accurate and reliable.

Ideally, there should be real-time traceability of cash movements in the company, so that corrections can be made to forecasts more quickly. To summarize, the forecast of expenses and income is an estimate of the money that will come in and out of a company. It is used to control cash, optimize resources and anticipate the needs that will arise. Does your company have an updated forecast for this quarter?
