Cost of Doing Business
Calculate your business cost of doing business (CODB) per day, week, month, and year. Enter fixed and variable costs with billable days to estimate daily operating cost.
About This Calculator
The Cost of Doing Business (CODB) Calculator helps business owners, freelancers, entrepreneurs, and managers determine their true daily operating cost. By entering your annual fixed and variable costs along with your billable days per year, you can understand exactly how much it costs to run your business each day.
This calculator is essential for setting profitable pricing, evaluating operational efficiency, and making informed financial decisions. The CODB is calculated by dividing your total annual operating costs by the number of billable days per year. For example, a business with $600,000 in annual costs and 200 billable days has a CODB of $3,000 per day.
What costs are included?
Fixed costs remain constant regardless of business activity — rent or mortgage payments, insurance premiums, salaried employee wages, software licenses, equipment leases, business permits, and membership fees. Variable costs fluctuate with business activity — raw materials, utilities, marketing and advertising, shipping and delivery, office supplies, and contractor payments.

Frequently Asked Questions
What is the cost of doing business?
The cost of doing business (CODB) is the total operating cost of a business measured on a per-day basis. It represents the amount of money required to run a business for a single day, calculated by dividing total annual costs by the number of billable days per year.
How do you calculate the cost of doing business?
The cost of doing business is calculated by dividing the total annual operating costs by the number of billable days per year. The formula is: CODB = Total Annual Cost / Billable Days Per Year. For example, if annual costs are $600,000 and there are 200 billable days, the CODB is $3,000 per day.
What costs are included in the cost of doing business?
The cost of doing business typically includes fixed costs (rent, insurance, salaries, licenses, equipment leases) and variable costs (materials, utilities, marketing, supplies, shipping). Together these make up the total annual operating cost of the business.
Why is knowing your cost of doing business important?
Knowing your CODB helps you set profitable pricing, evaluate operational efficiency, compare against competitors, determine break-even revenue, and make informed decisions about resource allocation. A lower CODB relative to competitors indicates better operational efficiency.
Can the cost of doing business be negative?
No, the cost of doing business cannot be negative. Since total annual costs and billable days per year are always positive values, the resulting CODB will always be a positive number reflecting the true cost of operating the business.
How many billable days are there in a year for most businesses?
Most businesses operate around 240 to 260 billable days per year after accounting for weekends, public holidays, and vacation days. In India, this is typically 240-250 days. In the US, it is around 250-260 days. In the UK, it is around 225-252 days depending on bank holidays and leave policies.
What is a good cost of doing business for a small business?
A good CODB varies by industry, location, and business size. Service-based businesses often have lower CODB than manufacturing. The key is to compare your CODB with direct competitors in your industry. If your CODB is lower than your competitors, your business operates more efficiently. If higher, look for ways to reduce costs or increase billable days.
How does cost per billable hour help with pricing?
The cost per billable hour helps you set minimum hourly rates. If your CODB per day is $3,000 and you work 8 hours per day, your cost per billable hour is $375. To be profitable, you must charge more than this amount per hour. This ensures your pricing covers all operating costs and generates profit.
