01
What is a pricing calculator?
A pricing calculator estimates a cost-based selling price for a product, service, project, or billing unit. This version combines direct cost, other per-unit variable cost, and a share of monthly fixed costs before applying a target profit margin.
Ecommerce businesses, retailers, manufacturers, agencies, freelancers, consultants, service companies, and SaaS companies using one consistent billing unit can use the result as a planning reference. It is not an automatic recommendation. It is not a promise that customers will accept the calculated price.
02
How to calculate a selling price
First identify the variable cost attached to one unit. Next divide monthly fixed costs by expected monthly unit sales. Add those figures to get total cost per unit, then convert the target margin from a percentage to a decimal and apply the price formula.
Expected Monthly Profit assumes all expected units sell at the exact calculated price. The displayed price is rounded to two decimals, which can make an achieved margin differ slightly if that displayed amount is used in practice.
03
Pricing formula using target profit margin
Target Margin Decimal = Target Profit Margin ÷ 100
Recommended Selling Price = Total Cost per Unit ÷ (1 − Target Margin Decimal)
Target Profit per Unit = Recommended Selling Price − Total Cost per Unit
Target profit margin is a share of selling price, not a share of cost. The calculation uses the unrounded price internally and applies two-decimal formatting only when displaying money.
04
How to calculate total cost per unit
Variable Cost per Unit = Direct Cost per Unit + Other Variable Cost per Unit
Total Cost per Unit = Variable Cost per Unit + Allocated Fixed Cost per Unit
Direct and other variable inputs should reflect real amounts incurred for each unit. Other variable cost can include packaging, materials, per-unit fulfillment, shipping paid by the business, or a fixed contractor amount per unit. It does not model fees calculated as a percentage of selling price.
05
How to allocate fixed costs per unit
Allocated Fixed Cost per Unit = Monthly Fixed Costs ÷ Expected Units Sold per Month
At a lower volume, more fixed cost is assigned to each unit. At a higher volume, allocated fixed cost per unit falls because the same monthly amount is spread across more units. Monthly Fixed Costs and Expected Units Sold must refer to the same monthly period; convert weekly or annual figures before mixing them.
06
Pricing calculation example
Suppose direct cost is $30 per unit, other variable cost is $5, monthly fixed costs are $10,000, expected monthly sales are 1,000 units, and the target profit margin is 20%.
$30 + $5 = $35 variable cost per unit
$10,000 ÷ 1,000 = $10 allocated fixed cost per unit
$35 + $10 = $45 total cost per unit
$45 ÷ (1 − 0.20) = $56.25 recommended selling price
$56.25 − $45 = $11.25 target profit per unit
$11.25 ÷ $45 = 25% equivalent markup
$11.25 × 1,000 = $11,250 expected monthly profit
$10,000 ÷ $21.25, rounded up = 471 units to break even
07
Profit margin vs markup
Profit margin divides profit by selling price. Markup divides profit by cost. A 20% target margin therefore produces a 25% equivalent markup in the example above. Entering the same percentage as markup would normally produce a different price.
The Pricing Calculator starts with costs, expected volume, and target margin. The Markup Calculator instead explains how an entered cost and selling price translate into markup and margin. The Break-even Calculator starts with an entered selling price and asks what sales volume covers costs.
08
Direct costs vs variable costs
Direct Cost per Unit is the primary production, acquisition, or service-delivery cost of one unit. Other Variable Cost per Unit captures additional fixed money amounts caused by each sale. Either input may be zero when the other correctly represents the unit economics.
Use a consistent unit. A manufacturer might use one item, an agency one deliverable, a consultant one hour, and a SaaS company one billing unit.
09
What should be included in monthly fixed costs?
Monthly fixed costs can include rent, base salaries, insurance, software, administrative costs, and fixed subscriptions that do not move directly with unit sales in this model. Use the portion relevant to the same business scope as the unit and sales estimate.
Do not mix weekly, monthly, and annual values without first converting them to a consistent monthly period.
10
How expected sales volume affects price
Expected volume controls only the allocation of fixed costs; it is not a demand forecast or guaranteed sale count. If actual volume is below the estimate, fixed cost per actual unit rises and actual margin may be below target.
If actual volume is higher, fixed costs are spread across more units. That can improve total profit under otherwise unchanged assumptions, but changing demand, price, and costs are outside this calculation.
11
How to interpret contribution per unit
Contribution per Unit = Recommended Selling Price − Variable Cost per Unit
Contribution first covers monthly fixed costs. Only after those costs are covered does additional contribution become profit. It is therefore not the same as net profit per unit, and it excludes costs not entered in the model.
12
How pricing affects break-even sales volume
Exact Break-even Units = Monthly Fixed Costs ÷ Contribution per Unit
The displayed result rounds the exact value up because a partial unit usually cannot be sold. A higher contribution can lower break-even volume, but a higher price does not guarantee demand or higher total profit.
13
What happens when costs are zero?
With zero monthly fixed costs, allocated fixed cost and break-even volume are both zero. When every entered cost is zero, cost-based math returns $0.00 but cannot derive a positive price from costs alone. It does not mean the product or service should be free.
Equivalent markup is N/A in that case because zero profit divided by zero cost is undefined. The calculator keeps the other zero results as numbers instead of replacing them with missing values.
14
Pricing products vs services
Product businesses can use acquisition, production, packaging, and fulfillment amounts per item. Service businesses can use one hour, project, engagement, or deliverable, provided direct labor and other variable costs use that same unit.
Shared overhead can be entered as monthly fixed cost and spread across the expected number of billing units. The quality of the result depends on choosing a meaningful, consistent unit.
15
Common pricing calculation mistakes
- Using target markup as though it were target profit margin.
- Leaving real direct or per-unit variable costs out of the inputs.
- Mixing monthly sales with weekly or annual fixed costs.
- Treating expected sales volume as guaranteed demand.
- Calling contribution per unit net profit per unit.
- Forgetting that a two-decimal displayed price is rounded.
- Assuming a currency selection converts the entered amounts.

Limitations of a cost-based pricing estimate
This model does not include sales tax, VAT, percentage transaction fees, marketplace commissions, payment fees, discounts, or refunds. A business must account for those and any other omitted costs separately.
It also does not measure competitor pricing, perceived value, customer willingness to pay, price elasticity, or whether the market will accept the calculated price. It does not forecast demand, optimize price, or run dynamic or scenario-based pricing. Cost-based price is a starting point for planning, not professional advice or an automatic recommendation.

Frequently asked questions
What is a pricing calculator?
A pricing calculator estimates a cost-based selling price from unit costs, allocated fixed costs, expected sales volume, and a target profit margin. It is a planning starting point, not a prediction of the price customers will accept.
What is the formula for calculating a selling price?
Add variable cost per unit to allocated fixed cost per unit to find total cost per unit. Then divide total cost per unit by one minus the target profit margin expressed as a decimal.
How do I calculate price from a target profit margin?
Convert the margin percentage to a decimal and use: Selling Price = Total Cost per Unit ÷ (1 − Target Margin Decimal). A 20% margin means profit is intended to be 20% of selling price.
What is total cost per unit?
Total cost per unit is direct cost per unit plus other variable cost per unit plus the share of monthly fixed costs allocated to each expected unit.
How are monthly fixed costs allocated per unit?
Monthly fixed costs are divided by expected units sold per month. The monthly cost period and monthly sales-volume period must match.
What is the difference between profit margin and markup?
Profit margin divides profit by selling price, while markup divides profit by cost. Because their denominators differ, the same percentage usually produces a different price.
Is a 20% margin the same as a 20% markup?
No. A 20% target margin on cost of $80 produces a $100 price and 25% markup. A 20% markup on the same cost produces a $96 price and a 16.67% margin.
How does expected sales volume affect the calculated price?
Lower expected volume allocates more monthly fixed cost to each unit and raises the cost-based price. Higher volume allocates less fixed cost per unit, but the entered volume is an estimate, not a guarantee.
What happens if actual sales volume is lower than expected?
Fixed costs are spread across fewer actual sales, so actual total cost per unit is higher and actual profit margin may fall below the target, assuming other values stay unchanged.
What is contribution per unit?
Contribution per unit is recommended selling price minus direct and other variable costs per unit. It first contributes to monthly fixed costs; it is not the same as net profit per unit.
How is expected monthly profit calculated?
Expected monthly profit equals recommended price times expected units, minus variable cost per unit times expected units, minus monthly fixed costs. It assumes every expected unit sells at the exact calculated price.
How is break-even sales volume calculated?
Monthly fixed costs are divided by contribution per unit. This estimates how many units cover the entered fixed and per-unit variable costs at the calculated price.
Why is break-even sales volume rounded up?
A partial unit usually cannot be sold. Rounding up gives the first whole-unit volume that covers all entered fixed costs rather than leaving a small amount uncovered.
What happens when monthly fixed costs are zero?
Allocated fixed cost per unit is zero and total cost per unit contains only variable costs. Break-even sales volume is zero because there are no fixed costs to cover.
What happens when all entered costs are zero?
The formula returns a $0.00 mathematical price, revenue, and profit, but it cannot derive a positive price from costs alone. Equivalent markup is N/A because dividing zero profit by zero cost is undefined.
Can the target profit margin be 100%?
No. At 100%, one minus the margin is zero, so the price formula would divide by zero. Values from 0% up to but not including 100% are accepted.
Can I use this calculator for services?
Yes. Agencies, freelancers, consultants, and service companies can treat one project, hour, deliverable, or other consistent billing unit as a unit and enter its direct and variable costs.
Should taxes and transaction fees be included?
The calculator does not separately model sales tax, VAT, percentage transaction fees, discounts, or refunds. Businesses must account for omitted costs themselves; only fixed money costs per unit belong in the per-unit inputs.
Does changing Currency convert the entered values?
No. Currency changes symbols and formatting only. It does not convert amounts or change any numerical result.
Does the calculated price guarantee the target profit margin?
No. The estimate assumes the entered costs, expected volume, and exact calculated price. Actual volume, costs, discounts, refunds, fees, and rounding the displayed price can change the achieved margin.
What are the limitations of cost-based pricing?
Cost-based pricing does not measure competitor prices, customer willingness to pay, perceived value, demand, price elasticity, or market acceptance. A higher price also does not guarantee higher total profit.
