Cost plus pricing is one of the many pricing strategies employed by companies in an attempt to increase their revenue and profit.
The basic idea behind cost plus pricing is to base your prices on the cost of production plus your desired profit margin. This makes it a very simple and safe pricing strategy. Using this strategy, you simply identify a price that you know will be above your cost of goods sold.
However, while it may be simple and safe, and you can justify it to your team, whether customers will pay that price or it is the highest price you could charge is a different conversation.
In this article, we will look at cost plus pricing, the rationale behind cost plus pricing, how to calculate a cost plus pricing price, and the pros and cons of cost plus pricing.

The rationale behind cost plus pricing
In a perfectly competitive market, prices are generally set by the market at the point where the short-run marginal cost equals the marginal revenue. However, in the long run, the marginal cost (i.e., the cost of the last unit produced) tends to overlap the unit cost (i.e., the average cost of all units), so in that case cost plus pricing tends to reach the same price point as the one found in a competitive market.
Where cost plus pricing is found commonly is in larger one-off contracts. For example, a car mechanic might use cost plus pricing for replacement parts when doing work on a car, while a general contractor might use cost plus pricing when drawing up a contract for a house renovation.
This is because, in cases where the cost structure is transparent to customers—for example, where you can find the contractor price of lumber at a local hardware store—the cost plus structure is seen as fair and reasonable.
The price has two main elements: the cost to the supplier and the supplier’s markup. This leads to simple negotiations where the basement price is baked into the negotiable range—the supplier isn’t going to accept cost-minus pricing—and the ceiling is the supplier’s desired markup.
For example, if a supplier is offering a cost plus 30% pricing scheme, instead of broad price negotiations, the customer is already restricted to the 30% portion of the price. If the customer manages to knock 20% off the margin, they’ve only actually reduced the price by less than 5%. While the customer may feel like they’ve gotten a big win, the final price is still acceptable to the supplier who is guaranteed a positive margin.
In markets with a lot of competition, especially where every company is seen as essentially the same, companies do not have a lot of room to increase prices or set prices using a different pricing strategy.
In these cases, a company can essentially collude with its competitors by following the industry standards when choosing its desired markup. Without putting too much time into researching the potential customers’ willingness to pay, the market structure, etc., a company can choose a safe, reasonable, and fair price.
The Cost Plus Calculation
The cost plus calculation has two parts. First, you need to figure out the cost of your product. Second, you need to multiply that cost by your desired margin. We will take a look at an example below, but first let’s go through the mechanics behind these calculations.
Mechanics
The cost plus pricing system can be broken down into three steps: calculate the total cost, calculate the unit cost, and add the markup.
Step 1: Calculate the total cost
There are two types of costs: fixed costs do not change based on the number of units produced, while variable costs do.
Total cost = fixed costs + variable costs
Step 2: Calculate the unit cost
The unit cost is simply the total cost divided by the number of units produced:
Unit cost = total cost/number of units
Step 3: Add the markup
The markup is the amount you wish to earn on each product or service sold. It is usually considered a percentage, but here this needs to be made a dollar value:
Markup = unit cost × markup percentage
This is then added to the unit cost to come up with the final selling price:
Selling price = unit cost + markup
Note that the markup percentage needs to be converted to a decimal for the first half of this step. You can also combine them by adding 1 to the value of the markup percentage expressed as a decimal. For example, a 30% markup can be written as 0.3, and plus 1 it is 1.3.
Example
Your company has fixed costs of $20,000, variable costs of $4,000, and sells 2,000 units. Your desired margin is 50%.
Your total cost is $20,000 + $4,000 = $24,000.
Your unit cost is $24,000/2,000 = $12.
Your selling price is $12 × 1.5 = $18.
In SaaS, the cost structure is generally broken down a bit differently. CAC (customer acquisition cost) and ACS (average cost of service), how much it costs to get a customer signed up (the marketing and advertising costs) and how much it costs to provide their service monthly, respectively, tend to be how costs are calculated.
Both can have fixed and variable costs. For example, ACS includes the variable costs of hosting and maintaining the platform as well as the amortization of the cost to develop and test the platform, which is a fixed cost.
The cost plus pricing system can still work, but you’ll need to figure out the average lifetime of your contracts, calculate the total cost, then figure out a desired markup, and finally get to a LTV (lifetime value) that matches the cost plus strategy.

The pros and cons of cost plus pricing
As with all pricing strategies, cost plus pricing has its pros and cons.
1. Advantages of cost plus pricing
The following are some of the advantages to using the cost plus pricing method.
i. Simple
Since you should already have a handle on what your expenses are and the margins you need to maintain a growth trajectory, cost plus pricing is an easy way to set your prices.
ii. Assured contract profits
Since costs are built into the pricing structure, every contract will be profitable.
iii. It takes few resources
This strategy doesn’t require anything in the way of market research or a review of competitor prices, so it is a cheap way to set prices.
iv. It provides a consistent rate of return
Since you put your desired margin at the heart of your pricing decisions, you know your approximate rate of return will remain stable.
2. Disadvantages of cost plus pricing
The following are some of the disadvantages of using the cost plus pricing method.
i. Ignores competition
Without consideration of competitors’ prices, there is a good chance you are charging way too much or way too little. While the former will leave you with no customers, the latter will be robbing you of higher profits and the cash flow needed to expand.
ii. Contract cost overruns
Suppliers have no incentive to work efficiently, so, while cost plus pricing might look reasonable to start, overruns often occur and the final price ends up higher than anticipated.
iii. It’s inefficient
Since all expenses are built into the price directly, your company is unlikely to operate lean. There is no reason to reign in unnecessary expenses.
iv. It doesn’t consider consumers
If your consumers aren’t privy to your internal cost structure, then cost plus pricing means little to them. A consumer would rather pay based on the value you give them than the cost you incur during production.
Evaluation of Cost Plus Pricing
While cost plus pricing is popular in certain markets, in others it won’t work. For SaaS, it is a reasonable way to internally define the minimum price you are willing to accept, but your customers will care little about the cost of providing your services.
Baremetrics is the obvious choice for SaaS businesses seeking to better track their revenue while making major pricing strategy changes.

FAQs
-
What is cost plus pricing?
Cost plus pricing is a strategy where you set your selling price by adding a target profit margin on top of your total production costs.
The calculation has three steps: add your fixed and variable costs to get total cost, divide by units produced to get unit cost, then multiply by your markup percentage to arrive at your selling price. For example, if your unit cost is $12 and your desired margin is 50%, your selling price is $18. It is one of the simplest pricing strategies available because it does not require deep market research or competitor analysis. For SaaS businesses, it works best as a floor-setting tool rather than a complete pricing strategy, since customers make purchase decisions based on value delivered, not your cost structure. -
What is the difference between cost plus pricing and value-based pricing?
Cost plus pricing sets price based on your internal costs plus a markup, while value-based pricing sets price based on what customers are willing to pay for the outcome your product delivers.
Cost plus pricing is internally focused. It guarantees a positive margin on every sale but has no relationship to perceived value or competitor pricing. Value-based pricing is externally focused and tends to produce higher prices for SaaS products because customers are paying for the business result, not your hosting bill. For subscription businesses, cost plus pricing is most useful as a minimum acceptable price floor. Once you know your floor, tracking MRR, LTV, and expansion revenue in Baremetrics helps you understand whether your actual pricing is capturing the full value customers get from your product. -
How do you calculate cost plus pricing for a SaaS business?
To calculate cost plus pricing for a SaaS business, add your customer acquisition cost and average cost of service, then apply your target markup to find your minimum viable price per customer.
Start by identifying your fixed costs such as platform development, infrastructure, and salaries. Add your variable costs including hosting, payment processing, and customer support. Divide total costs by your projected customer count to get a per-customer unit cost. Finally, multiply that unit cost by your markup percentage to set your price floor. This floor tells you the lowest price at which every contract stays profitable. Use Baremetrics to monitor whether your actual MRR per customer consistently clears that floor as your cost structure shifts over time, especially during growth phases when variable costs can spike unexpectedly. -
When should a SaaS company use cost plus pricing?
A SaaS company should use cost plus pricing primarily as a way to define the minimum price it is willing to accept, not as the final basis for its go-to-market pricing strategy.
Cost plus pricing is most practical in the early stage when market data is limited and you need a fast, defensible way to set an initial price. It is also useful in custom enterprise contracts where cost transparency is expected and negotiations focus on margin rather than list price. For most subscription businesses at scale, cost plus pricing alone leaves money on the table because it ignores willingness to pay and competitive positioning. Pair it with cohort analysis and LTV data from Baremetrics to make sure your pricing is not just profitable on paper but also competitive in the market. -
What are the main disadvantages of cost plus pricing for subscription businesses?
The biggest disadvantages of cost plus pricing for subscription businesses are that it ignores competitor pricing, overlooks customer willingness to pay, and gives your team no incentive to control costs.
Because the method is entirely internally focused, you can end up pricing yourself out of the market or, equally damaging, leaving significant margin on the table when customers would happily pay more. For SaaS specifically, customers rarely know or care about your infrastructure costs. They evaluate price against the value your product delivers. Cost overruns are another risk: when every expense feeds directly into the price, there is little pressure to run lean. Monitoring your actual churn rate and MRR growth alongside your cost structure helps you catch the moment your pricing stops working, whether it is too high or too low. -
How can I run experiments to test new pricing and monitor the impact on MRR?
To test new pricing and measure its impact on MRR, define a clear baseline period, make one pricing change at a time, and track MRR movements broken down by new, expansion, contraction, and churned revenue.
Start by segmenting your subscriber base so you can compare cohorts on the old price against cohorts on the new price. Watch for changes in trial-to-paid conversion, average revenue per account, and voluntary churn rate in the weeks following the change. Baremetrics separates new MRR, expansion MRR, contraction MRR, and churned MRR in real time, so you can see immediately whether a price increase is expanding revenue from existing customers or accelerating cancellations. Running pricing experiments without this level of metric granularity makes it almost impossible to isolate whether a revenue shift came from your pricing change or another variable. -
What platforms offer automated failed payment recovery for subscription businesses?
Baremetrics Recover is a purpose-built tool that automatically retries failed payments and sends smart dunning sequences to reduce involuntary churn for subscription businesses.
Involuntary churn caused by failed payments is one of the most recoverable revenue leaks in a SaaS business. Most subscription teams underestimate how much MRR they lose this way because it never shows up as a deliberate cancellation. Baremetrics Recover connects directly to your Stripe data, identifies failed charges, and retries them on an optimized schedule while sending customised recovery emails to subscribers. Because it sits inside the same platform as your MRR and churn dashboards, you can see in real time how much revenue has been recovered and how involuntary churn is trending as a share of your total churn rate.
