The Customer Acquisition Cost (CAC) measures how much a company spends to obtain new, additional customers. Oftentimes, it’s used with the customer lifetime value (LTV) metric, which also projects the customer’s profitability to calculate the newly acquired customer’s value.
It’s primarily used to measure a business’ sales and marketing departments to figure out their profitability, profit margin and return on investment figures.
How to Calculate
CAC = Sales and Marketing Expense/Number of New Customers
Where: Examples of the expenses include product and service promotion expenditures, special compensation and commissions, regular wage payments, and operating expenses.
The tally of newly acquired customers is simply how many new, unique contracts the business acquired. It’s important to keep the expenses and customer acquisition numbers consistent over the same periods.
Why It’s Important
Business owners and their managers, along with investors, can look at sales and marketing efforts from a return on investment on their expenditures and outcomes. For example, there could be multiple channels that sales and marketing utilize to obtain new customers over a quarter, half-year, or 12-month period (such as email marketing, social media marketing, conferences, etc.). Based upon each channel, the customer acquisition cost is determined by dividing the financial outlay per customer acquired.
From there, each channel can be analyzed to see which one works well and, equally important, which ones don’t work well and either need to be discontinued or modified. Internal stakeholders and external investors (both existing and potential) can look at trends to see if existing management is productive or needs to be replaced with more competent individuals.
Accounting Considerations
Based on FASB’s Accounting Standards Codification 340-40, businesses are required to document and capitalize incremental costs of securing new customer business if the related expenses are projected to be recouped.
An incremental cost in the scope of obtaining a contract is a cost an entity incurs to obtain a contract that wouldn’t have been incurred if the contract hadn’t been obtained.
While a sales commission (be it fixed or a percentage of a new contract) may be considered an eligible incremental cost to one of its employees, it’s not necessarily always the case. Rather, the true test of whether an incremental cost is capitalizable depends on the subjective interpretation of whether a mandated financial expenditure for an incremental cost is attributed to signing a contract with a new customer.
The following sample situations often require more investigation to determine whether the capitalization of costs is applicable:
- Equity issuances based upon meeting production and essential function goals
- Employee compensation according to previous years’ executed contracts
- Sales commissions allocated over multiple time frames and/or to more than one employee for a single contract.
ASC 340-40 also stipulates the amortization schedule of capitalization costs of obtaining a customer contract on a scheduled timeline that follows the delivery to the customer of the contracted goods or services.
Conclusion
While the customer acquisition cost may be straightforward, when it comes to subjective cases, businesses that have experience with murkier situations are able to make the most of their subjective sales and marketing expenses when navigating the tax and accounting landscape.

Safeguard American Voter Eligibility Act (S 1383) – Also known as the SAVE America Act, this bill passed in the House on Feb. 11 but stalled in the Senate due to the Democrat filibuster. The bill would require states to verify documentary proof of citizenship and current residential address when Americans apply for federal voter registration. The easiest documentation would be a birth certificate or passport that confirms their current legal name (most women change their last name after marriage, so they require additional documentation, such as a marriage certificate). However, research from the Bipartisan Policy Center found that nearly 1 in 10 registered voters do not have access to their birth certificate, and 52 percent do not have an unexpired passport with their current legal name. Note that these registration requirements kick in any time current voters update their registration, such as for an address change or to switch political party affiliation. The bill also requires a specific type of photo ID to cast a ballot. A driver’s license is acceptable, but not student IDs or a tribal ID that lacks an expiration date (which tribal IDs do not contain). The president is also insistent that the legislation include unrelated restrictions for transgender Americans. The debate over this bill continues in the Senate.
Businesses are moving beyond basic automation into a new era of intelligent, self-directed systems. While automation helps with streamlining repetitive tasks, agentic AI workflows enable systems to make decisions, take action, and continuously improve with minimal human oversight.
It might be hard to believe, but yes, it’s almost the middle of the year and the perfect time to take a look at how you’re doing financially: are you fiscally fit or do you need a few adjustments? Whether it’s saving more, paying down debt, or prepping for retirement, you still have time to effect change. Here are a few ways to get started.
If the IRS sends notice that you’re being audited, you’re likely to become anxious. However, not all audits mean you did something wrong. In most cases, it is simply a matter of verifying information on a tax return or perhaps correcting a minor error. Knowing what to expect – and how to respond – can help alleviate stress and make the audit more manageable.
When it comes to raw materials, especially for fossil fuels, it’s essential to evaluate existing and potential production capabilities for such companies. Using the EV/2P Ratio is a powerful tool when evaluating fossil fuel-related companies.
Artificial intelligence is driving an unprecedented surge in data center construction. Developers, private equity sponsors and their tax advisors are navigating a complicated web of questions that touch everything from ownership structure to site selection to power sourcing. Get the early decisions wrong and the tax consequences can follow a project for years.
Picture two things happening at the same time. The agency responsible for reviewing your tax return is understaffed and buried under a backlog, and the software that the agency uses to catch filing errors just keeps getting better.

21st Century ROAD to Housing Act (HR 6644) – As many local governments face the problem of rising affordability and severe housing shortages, this bipartisan bill would update existing housing programs to increase the housing supply, as well as streamline federal regulations that slow construction. Among its provisions, the legislation would authorize a pilot program designed to convert vacant or underused buildings into residential housing, issue grants for infrastructure improvements for utilities and transportation, and include construction of new housing units for low- and moderate-income residents. The legislation was introduced on Dec. 11, 2025, by Rep. French Hill (R-AR). It originally passed in the House on Feb. 9, but the Senate made changes before passing it on March 12. It has returned to the House for a final vote.
