How to Calculate Your True Cost Floor (Before You Set Any Price)
Most founders undercharge because they undercount. They forget to include their time, their tools, their tax rate, and their cost of customer acquisition. The result is a price that feels right but erodes their margin every month. Here is how to find the real number.

The quick answer
Your cost floor is the minimum price at which one more sale makes financial sense. It includes direct costs, allocated overhead, payment processing fees, your time at a fair rate, and a margin buffer for taxes and reinvestment.
Side-by-side breakdown
Simplified cost floor (what most founders calculate): materials + direct labor + software used for this delivery. This understates costs by 30-50% for most businesses.
True cost floor (what you actually need): direct materials + direct labor at your target hourly rate + allocated overhead (rent, tools, subscriptions divided by client count) + customer acquisition cost + payment processing fee + tax provision (25-30% of net) + reinvestment margin (10%).
When simplified is enough
For a quick gut-check before a sales call, simplified cost floor is better than nothing. If your proposed price is 3x or more above your simplified cost, you likely have margin. Use the simplified number to set a floor, not to set your final price.
When to do the full calculation
Do the full calculation before you publish any pricing page, before you take on a recurring client at a fixed rate, and annually as your business scales. When you add employees, tools, or overhead, your cost floor shifts — and your prices may need to shift with it.
The verdict
Build a simple spreadsheet with three rows: direct costs, allocated overhead, and your time. Price at 2x your true cost floor for product businesses and 3x for service businesses. If the market will not bear that, your offer needs to change before your price does.
How to get started
Open a spreadsheet and list every cost you incurred in the last 30 days. Divide fixed costs by the number of clients or units you served. Add 30 minutes of your time per client at the hourly rate you would hire someone to replace you at. That bottom line is your cost floor. Does your current price cover it with room?

FREQUENTLY ASKED QUESTIONS
Should I include my own salary in my cost floor?
Yes — at the rate you would pay someone competent to replace you. If you value your time at $0, your pricing will reflect that and so will your business decisions. Even if you are not paying yourself yet, include it to model sustainability.
What if my price floor is above what the market pays?
That is important information. It means either your costs are too high, your target market is wrong, or your offer is not differentiated enough to command the price you need. Solve the offer problem before cutting your prices.
