Cost Based Pricing Calculator
Full absorbed cost, then a margin on top.
Calculate price from fully absorbed cost, direct costs plus allocated fixed overhead, and a target margin.
Fully absorbed price
$40.00
$12.00 of overhead per unit
The allocation depends on a volume assumption. If sales come in below it, the overhead per unit rises and the price no longer covers the fixed base.
How the Cost Based Pricing Calculator works
Cost-based pricing allocates a share of fixed overhead into every unit before applying margin. It guarantees that overheads are covered if you hit your volume assumption, and quietly misprices everything if you do not.
Also known as: cost plus pricing · price from cost calculator · cost driven pricing · cost based
The maths behind it
Cost-based pricing derives the price from the cost and a target margin or markup: price = cost ÷ (1 − margin), or cost × (1 + markup). It is the only pricing method that is pure arithmetic, which is both its appeal and its weakness.
It answers what you need to charge. It does not answer what anyone will pay, and treating the output as the price rather than as the floor is the source of most of the trouble it causes.
Putting numbers to it
Cost $22, target margin 55%: price $48.89. If competitors sell comparable products at $75, the cost-based price has left $26 a unit on the table, 53% more revenue available for the same product at no additional cost.
Now the reverse. Cost $34, same target: price $75.56. If competitors sell at $59, the cost-based price is unsellable and the calculation is telling you the cost base is wrong rather than the price.
Both errors come from the same source: the method has no input from the market at all, so it produces prices that are systematically too low on differentiated products and too high on commodities.
Where it is unreliable
It embeds inefficiency. A supplier price 20% above market flows straight into a retail price 20% above competitors, and the method provides no mechanism for noticing that anything is wrong.
It also allocates fixed costs by a rule of thumb, and the allocation determines the price. A product carrying an even share of overhead when it consumes far less warehouse space than its neighbours is being priced by an accounting convention rather than by anything real.
How to act on this
Use it as the floor and set the price from the market, checking it clears the floor. Where the market price is well above the floor, the difference is captured value; where it is below, the product needs a cheaper cost base or should not be in the range.
Make sure the cost is complete before trusting the floor. An invoice price rather than a landed and fulfilled cost produces a floor that is 30% too low on imported goods, which is worse than having no floor at all because it feels rigorous.
When cost-plus is genuinely the right method
It works well in three situations. Where price is regulated or contractually tied to cost, as in some government and utility contracts. Where the product is a true commodity and the market price is already known, so cost-plus is really a viability check. And for custom or one-off work, where there is no market reference at all.
For custom work it is the only method available, and the risk is different: underestimating the hours rather than misjudging the market. A cost-plus quote on bespoke work should carry a contingency, because the estimate is the variable rather than the margin.
For everything else, differentiated consumer products with a competitive set, cost-plus is a floor and value-based or competitive pricing sets the number. Businesses that use it as the method rather than the check are usually leaving the most money on their best products, which is exactly the wrong place to be leaving it.

Frequently asked questions
How does cost-based pricing differ from cost-plus?
Cost-plus applies a markup to direct costs only. Cost-based absorbs a share of fixed overhead first, so the price covers a portion of rent and salaries as well as materials.
How do I allocate fixed overhead per unit?
Total fixed costs ÷ expected units. The weakness is circular: fewer sales means a higher allocation, which suggests a higher price, which usually means fewer sales still.
What volume assumption should I use?
A conservative one. Allocating overhead across optimistic volume understates unit cost and produces prices that do not cover your fixed base when reality falls short.
When is this the wrong approach?
In competitive markets where the price is effectively set by others. There, work backwards: take the market price, subtract the margin you need, and find out whether your cost base can fit inside what remains.
