How to Calculate Business Startup Costs: A Practical Guide

Business startup costs equal your one-time costs, plus your monthly costs multiplied by the number of months it takes to break even, plus a cash buffer. As of September 2026, the first costs to plan for in a U.S. LLC are state fees, and they vary widely: a Wyoming formation is $100, while a California LLC costs $890 in the first year. These are costs you can't change, and they are the first costs you need to consider.

Startup costs for a business are relatively straightforward and can be expressed with the following equation: one-time costs + (monthly costs x months to break-even). A cash buffer is added to the result. Founders generally quote the one-time costs of the equation comfortably, but have difficulty estimating the other two terms. A computer and a domain name are one-time costs, but how long will you need to buffer for state compliance? How long will it take to break-even?

This article includes the formula for break-even analysis, gives a few example numbers, provides state and federal fees, and explains the tax code that allows break-even analysis. 

What do business startup costs include?

Business startup costs fall into two groups:

• One-time costs: legal fees and equipment.
• Repeated costs: costs incurred over the life of the business, such as subscriptions, bookkeeping, and state fees.

The worksheet from the SBA is similar to the one from the website and can be filled out and used for free.

How do you calculate business startup costs?

The formula to determine the break-even point is: Total = one-time costs + (monthly costs x months to break-even) + cash buffer

The example below includes a one-person business with a paid online resource.

Swap in your own quotes. The structure matters more than these figures. The nine months is a guess about when revenue will cover costs, and an optimistic guess is the most common reason a total comes out too low. Three months for the buffer is a planning habit, not a rule.

What impact do state fees have on business startup costs?

State fees are the most varied of all the costs, and they often change. Here are some examples from September 2026:

Delaware raised its flat tax on LLCs to $400 beginning with the 2026 tax year, so an LLC formed in 2026 would owe $400 the following year. Many sources still show the old $300 flat tax.

In California, the $800 franchise tax is also charged even if the LLC made no money that year. The first year tax for LLCs formed between 2021 and 2023 was adopted so the total cost for LLCs formed in those years was between $890 and $898. Like Wyoming, forming in California does not avoid the tax. An LLC that does any business in California should check with the Franchise Tax Board.

Most states also charge a separate fee for a registered agent. If you have a physical address in the state, you can act as the registered agent. Otherwise, you will have to hire an agent, and that cost should be added to the ongoing costs.

What federal costs should be included in the budget for a new business?

EIN

An Employer Identification Number (EIN) from the IRS is free. You can find third party websites charging for this service. The IRS's online EIN application typically states an SSN or an Individual Taxpayer Identification Number (ITIN) is required to complete the application. Founders without either can submit a Form SS-4 to the IRS to receive an EIN.

Beneficial ownership reporting

As of August 2026, domestic Limited Liability Companies (LLCs) no longer have to pay to disclose their true owners. FinCEN issued a final rule in August 2026 stating U.S. entities would not have to disclose their true owners under the Corporate Transparency Act. Non-U.S. entities, including those registered to do business in the U.S., may be subject to true owner reporting.

Form 5472

Foreign founders should also include a pro forma Form 5472. If a single member foreign LLC is owned by an individual, the LLC would also have to file Form 5472. The penalty for not filing the form is $25,000. It is advisable to budget time for accountants to complete this form.

Are business startup costs deductible?

Yes, to a degree. Section 195 of the Internal Revenue Code allows a business to deduct up to $5,000 of startup costs and up to $5,000 of organization costs in the year a business opens its doors. The deductions are reduced by the same dollar amount if the total costs for each category reach $50,000, and are completely eliminated at $55,000. The remaining costs are recovered through business operations over a 15 year period.

Using the above example, the maximum first year deduction would be $2,000, and the remaining $51,000 would be recovered over 15 years. 

Generally, the costs incurred to research and prepare to start a business are considered startup costs. The costs to organize a business, e.g., to incorporate or form a limited liability company, are considered organization costs. The rules above govern how costs are recovered based on the structure of the business. Therefore, it is best to consult with a Certified Public Accountant to better understand the rules based on your individual business structure.

What is the significance of separating startup costs and operating costs?

Separating costs becomes important when establishing what costs were incurred before the business started operating. There are typically two issues:

• Payments made prior to the launch of the business using the entrepreneur's personal credit card.
• The absence of a defined date for the launch of the business.

It is ideal to open a business bank account and make all business related payments from the account prior to the account being set up. If payments are made using personal funds, reimburse yourself and document the reason for the payment. It is important to retain all business receipts. The launch of the business should be clearly defined and ideally should be set in the beginning of the business. Entrepreneurs who are focused on the details typically set up bookkeeping processes for the business. This allows clarity on the costs that should be attributed to the business and costs that should be attributed to the operation of the business.

Practical checklist

• Separate costs by whether they occur only once or recur.
• State fees change. The fees on the Secretary of State's and tax department's websites are current. Old blog posts may give you a fee estimate, but may not be current.
• What is a registered agent? What is the cost?
• How long do you think it will take your business to break even? Add a pessimistic buffer.
• Record your launch date and save all receipts.
• If your LLC has a non-resident alien (of the U.S.) owner, you must prepare Form 5472.

Common mistakes

• The startup costs for years 1 and 2 may be higher than estimated. California and Delaware charge annual reports of $800 and $400 respectively. EINs are free from the IRS.
• Personal and business expenses should be kept separate.
• Expenses are often amortized. There are limits on the deductions in the first year.
• Revenue may be later than expected. A cash flow pessimistic buffer should be anticipated.
• The average break even for startups is 18 months. 
• The cost of a business is often less than estimated and start up costs may be overestimated. Your estimates should be less than the actual costs.

FAQs

How much does it cost to set up a business in the U.S.?

This really depends on the nature of your business. From a legal perspective it can cost as little as $100 to set up an LLC in Wyoming. Beyond that, you'll need to raise money and buy equipment and supplies to get your business up and running.

Do startup costs have any impact on taxes?

Yes. You have the option to deduct up to $5,000 of startup costs and/or $5,000 of the costs of setting up a business and would have to capitalize the remainder to expense over a period of 15 years.

Is there a cost to obtain an Employer Identification Number (EIN)?

No. The IRS does not charge a fee for issuing an EIN.

Is it necessary to establish an LLC in order to determine startup costs?

No. In fact, the costs associated with starting a business are typically determined before an entity is established. Once again, you'll want to check with your state to see what the requirements are.

How much cash should a business keep on hand?

There are no hard and fast rules here. Many businesses plan to have three months of expenses on hand. The idea here is to have enough cash on hand to carry you over until the business starts bringing in revenues.

Do founders located outside the U.S. face different startup costs?

Yes. A foreign business owner who owns a single member LLC will have to file a Form 5472, and a founder who does not have an SSN or ITIN will have to submit a Form SS-4 to receive an EIN.
