Forecasting Capex requires a solid understanding of your company's strategic planning and capital structure. A well-planned capital structure can significantly impact your ability to fund and execute capital expenditures.
A company's capital structure is typically composed of debt and equity, with debt consisting of short-term and long-term loans. The optimal capital structure is one that balances debt and equity to minimize costs and maximize returns.
To accurately forecast capex, you need to consider your company's growth plans and future cash flows. This involves analyzing your business's historical data and industry trends to identify areas where investments are needed.
A key consideration in forecasting capex is the cash flow generated by your business. This can be affected by factors such as sales growth, operating expenses, and working capital requirements.

Historical and Industry Ratios
Historical and Industry Ratios are two important methods for forecasting capex. You can use the industry capex ratio, which is the average capex ratio of the company's peers or competitors, to estimate capex for your target company.
A different take: Capex Ratio
To apply this method, you need to identify a relevant set of comparable companies and calculate their average capex ratio for the past three to five years. This ratio can be useful when the company's historical capex ratio is not representative of its future needs.
You should also consider the stage of the company under evaluation relative to the peer group, as growth stage companies tend to have more new capex than just maintenance capex. This can change the forecasted capex substantially.
Here are some general guidelines for using industry benchmarks:
- The company operates in an established industry with clearly defined norms for capital expenditures.
- The business’ has similar spending patterns to its peers.
- There is adequate data available on industry spending patterns.
On the other hand, you shouldn't use industry benchmarks for CapEx forecasting when:
- The company operates in a unique or emerging industry.
- Its business model or growth trajectory is significantly different than its peers.
- There is limited or unreliable data available on industry spending trends.
Historical Ratio
In the past, the current ratio was a key indicator of a company's liquidity. Typically, a current ratio of 2:1 or higher was considered healthy.
The historical ratio of current assets to current liabilities in the manufacturing industry has been around 2.5:1 for the past decade. This ratio has remained relatively stable over time.

A company with a current ratio of 1.5:1 was considered to be in a precarious financial position. This ratio was often seen as a warning sign for potential financial difficulties.
The average current ratio for the retail industry has been around 1.8:1 over the past five years. This ratio has varied slightly depending on the specific retail sector.
In general, a current ratio of 1:1 or lower was often seen as a sign of financial distress. This ratio indicated that a company was struggling to meet its short-term obligations.

Industry Ratio
The industry ratio is a useful method for forecasting capital expenditures. It involves looking at the average capex ratio of a company's peers or competitors.
To apply this method, you need to identify a relevant set of comparable companies. This can be based on factors such as size, geography, and financial health.
The average capex ratio can be calculated over a period of three to five years. This will give you a sense of the industry's typical spending patterns.
It's essential to consider the stage of the company under evaluation relative to the peer group. Growth stage companies tend to have more new capex than just maintenance capex, which can change the forecasted capex substantially.
For example, if you're evaluating a company in the growth stage, you may need to adjust the forecasted capex to account for the increased spending on new projects.
Here are some key considerations when using the industry ratio method:
- Identify a relevant set of comparable companies
- Calculate the average capex ratio over three to five years
- Consider the stage of the company under evaluation
- Adjust the forecasted capex accordingly
Strategic Planning
Strategic planning is a crucial step in forecasting capex. It involves creating a detailed and realistic plan based on the company's specific projects, initiatives, and goals.
To apply this method, you need to identify the major capex items that the company plans to undertake in the future, such as acquisitions, expansions, upgrades, or replacements. This requires more information and analysis, but it can capture the nuances and dynamics of the company's investment strategy.
You also need to estimate the timing, cost, and benefits of each item, and then allocate them to the appropriate forecast periods. This can be a time-consuming process, but it will give you a more accurate forecast.
Some companies may provide guidance on their capex plans, which can be used to improve forecasts. For example, the CFO may reveal information on planned new store openings, the cost of opening a new store, and the ratio of rented to bought stores.
You can use this information to model your capex forecasts and make more informed decisions.

Capital Expenditure Methods
You can forecast CapEx in a financial model by using one of five main options. The most straightforward approach is to review past capital expenditures and estimate future spending based on patterns. This involves looking at the company's financial data from past years, typically 3-10 years.
Discounted cash flow analysis is based on explicit assumptions and future cash flow projections, including CapEx. To use this method, you'll need to make predictions for CapEx, as well as other key items like operating expenses and changes in net working capital.
In contrast, accounting numbers like revenue and assets are subject to accounting rules and assumptions that don't accurately reflect future potential. This is why discounted cash flow analysis is a valuable tool for company valuation and DCF analysis.

Depreciation and Amortization Projection
Depreciation and Amortization Projection is a crucial aspect of forecasting capital expenditures. It's based on the net value of property, plant, and equipment (PP&E) and intangible assets listed on the balance sheet, which grow as a result of capital expenditures.
These projections align with the estimated useful lifespans established by management's accounting policies. A common way to estimate this is by considering the ratio of gross fixed assets to depreciation and amortization expenses.
You can also use a depreciation schedule to show the yearly depreciation expense of an asset over its useful life. For example, if a company buys a machine for $100,000 with an estimated useful life of 10 years, the depreciation schedule would show that the depreciation is $10,000 every year.
A useful method for forecasting capex is to use the depreciation plus maintenance capex formula, which is based on the assumption that the company will invest enough to maintain its existing asset base. This method works best when the company has a stable or declining growth rate, and there are no significant new capex projects planned.
Here are the key factors to consider when using the depreciation plus maintenance capex method:
- Estimate the maintenance capex, which is the amount of capex required to keep the PP&E at the same level of efficiency and functionality.
- Use a percentage of depreciation, such as 100% or 120%, to estimate the maintenance capex.
- Add the maintenance capex to the projected depreciation for each forecast period.
By considering these factors, you can accurately forecast depreciation and amortization expenses and make informed decisions about capital expenditures.
Fixed Amount Assumption
One way to approach capital expenditure forecasting is by assuming a fixed amount each year. This method involves using a fixed number for the CapEx projection, such as the average historical absolute value of CapEx in the balance sheet.
You can set a fixed amount for capital expenditures every year, which makes budgeting and forecasting easier. This approach can be especially helpful for companies with relatively stable capital expenditure needs.
The fixed amount assumption can be based on the average historical absolute value of CapEx in the balance sheet, as seen in example #4. This provides a reliable reference point for forecasting purposes.
Using a fixed amount assumption can also help you avoid overestimating or underestimating capital expenditures, which can have significant impacts on your financial planning.
5 Additional Considerations
When forecasting capex, it's essential to consider the impact on other items on the balance sheet and P/L. This ensures that the capex DCF forecast doesn't lead to a vast deviation in previous trends unless supported by markedly different future growth or expansion plans.
Seeing the full picture is crucial in the number crunching art of capex projection. An upward bias in capex can lead to lowered profitability, which in turn will impact many other ratios.
Here are some key things to consider:
- Ensure that the capex forecast aligns with the company's overall growth strategy.
- Consider the potential impact on other balance sheet items, such as debt and equity.
- Review the company's historical trends and adjust the forecast accordingly.
- Consult with experts, such as Jasmeet Minhas, CFA, MBA, who have experience in corporate finance and strategy.
For example, if an upward bias in capex leads to lowered profitability, it may impact other ratios such as the debt-to-equity ratio or the return on equity.
Capital Structure and Projections
To accurately forecast capital expenditures, it's essential to consider a company's capital structure and how it will evolve in the future. Leverage ratios such as debt to capital, debt to equity, and debt to EBITDA are often used as the forecast object to project future debt and equity levels.
Analysts should look at historical company practices to gain insight into how the company has managed its capital structure in the past. This can provide a baseline for future projections.
Management's financial strategy is also crucial in determining the company's future capital structure. They may provide guidance on target capital structure, which can inform the forecasting process.
Debt covenant ratios, such as net debt to EBITDA, are another important consideration in projecting a company's future capital structure. These ratios can help determine the company's ability to meet its debt obligations.
Capital expenditures can be broken down into maintenance, growth, and acquisitions, and analysts should consider these different categories when projecting a company's future capital structure.
Financial Models
In the world of financial modeling, accuracy is key. You can't just throw numbers around and expect a reliable forecast. Financial models like the Discounted Cash Flow (DCF) model rely on explicit assumptions and future cash flow projections.
CapEx is a crucial metric in these models, measuring a company's ability to create value and generate revenue. It's not just about accounting numbers, but about actual cash flows.
The DCF model takes into account forecasts for key items like operating expenses (OpEx), NOPAT, CapEx, and changes in net working capital. This ensures a comprehensive understanding of a company's financial situation.
DCF Model
The DCF Model is a powerful tool for evaluating a company's intrinsic value. It focuses on actual cash flows, not accounting numbers, to give a more accurate picture of a company's ability to create value and generate revenue.
Cash flows are a key metric in DCF analysis, measuring a company's ability to create value and generate revenue. They're more reliable than accounting numbers because they're not subject to accounting rules and assumptions.
In a DCF Model, you'll need to make predictions for a company's future financial metrics, including CapEx. CapEx is a critical component of DCF analysis, representing a company's future plans for expansion.

To forecast CapEx, you'll typically review a company's past capital expenditures and estimate future spending based on patterns. This can be a challenging task, especially without guidance from the company itself.
Discounted cash flow analysis is based on explicit assumptions and future cash flow projections of key items, such as operating expenses, NOPAT, CapEx, and changes in net working capital.
Revenue Function
Companies need to invest in capital expenditures to support growth, and a good way to measure this is by looking at CapEx as a function of sales.
An increase in sales means the company needs more employees and equipment to fulfill the delivery of the products or services it sells.
To do this, you divide CapEx by revenue each year, which will give you a percentage.
This percentage can then be analyzed for trends, such as whether it grows every year or stays constant.
If the percentage stays constant, you can assume it will continue to do so by using a moving average.
CapEx will be dependent on your forecast assumptions for revenue growth, so you need to already have sales projections before using this method.

Types of Capital Expenditures
When forecasting capital expenditures, it's essential to understand the different types of capex. There are two main categories: maintenance capital expenditures and growth capital expenditures.
Maintenance capital expenditures are necessary to sustain the current business, and forecasts for these are often based on historical depreciation and amortization expenses, usually with a small upward adjustment to account for inflation in capital goods.
For businesses with low fixed asset turnover, maintenance capital expenditure requirements can be quite high. I've seen this firsthand in companies that rely heavily on old equipment and struggle to upgrade.
Growth capital expenditures, on the other hand, are needed to expand the business. These forecasts are more discretionary and are tied to management's expansion plans and revenue growth.
Here's a breakdown of the two types of capex:
- Maintenance Capital Expenditures: Sustaining the current business
- Growth Capital Expenditures: Expanding the business
Frequently Asked Questions
How to forecast expenditure?
To forecast expenditure, start by adding a percentage increase (typically 4%) to last year's costs. This is a basic step, but there's more to it to ensure an accurate forecast.
What is the rule of thumb for CapEx?
The general rule of thumb for CapEx is to set aside 1-2% of a property's value annually, but actual needs may vary. This percentage can be adjusted based on specific property requirements and investment strategies.
