Pricing Calculator — Find the Right Selling Price Instantly

Name: Pricing Calculator
Author: James Blanckenberg

Last reviewed: 17 May 2026

Set the optimal selling price from cost and target margin (or markup). Adds VAT or sales tax automatically by region.

To calculate selling price from cost and target margin: Selling Price = Cost ÷ (1 − Margin ÷ 100). For a $20 cost at 40% target margin, the selling price is $33.33. Add VAT/sales tax on top where applicable (20% UK, 15% SA, varies by US state).

How it works

Toggle between margin-based pricing (you want X% margin on each sale) and markup-based pricing (you want to add X% on top of cost). The calculator returns the price both before and after tax. Tax pre-fills based on your region: 0% for the USA (sales tax added at checkout), 20% for the UK (VAT), 15% for South Africa (VAT).

Common mistakes

Anchoring to a competitor's price — copying a competitor's shelf price tells you nothing about whether they are profitable. They may be running at a loss to win market share, may have lower cost inputs, or may be inflating volume on the way to a sale. Always price from cost plus target margin first, then check competitor pricing as a sanity test.
Forgetting tax displays differ by region — UK and SA consumer prices must be VAT-inclusive; US prices typically exclude sales tax until checkout. A $100 net target price is shown as $100 in the US but should display at $120 in the UK and $115 in SA. Mixing the two creates margin shortfalls when you reconcile against the bank deposit.
Setting prices without testing psychological breakpoints — the calculator may suggest $73.14, but customers respond very differently to $69, $75, and $79. Always round the calculator output up to the next psychological price point ($69, $79, $99) — the small premium absorbs future cost rises and signals deliberateness rather than algorithmic pricing.

When to use this calculator

Use this when you are launching a new product, repricing an existing one, or moving from cost-plus to margin-based pricing. It is built to answer "what should I charge to earn X% margin on this cost?" in one step, with VAT/sales tax already baked in for the region you operate from.

If you only want to add a fixed percentage on top of cost (without thinking in margin), the Markup Calculator is simpler. If you are pricing your time on a project, use the Freelance Rate Calculator to find the hourly rate first, then price the engagement here.

See the formula

Selling Price (from margin) = Cost / (1 − Desired Margin / 100)
Selling Price (from markup) = Cost × (1 + Markup / 100)

Example (margin mode): Cost = $20 | Target Margin = 40%
  Selling Price = $20 / 0.60 = $33.33
  Equivalent Markup = ($13.33 / $20) × 100 = 66.7%

Worked example

A Cape Town management consultant prices a six-month strategy engagement. Internal cost basis: 200 billable hours at R600 per hour of loaded internal cost (senior time plus a junior analyst), for a total of R120,000. Target gross margin is 40% — the consultant's historical average and what overhead, business development, and downtime need to absorb.

Selling price from margin = cost ÷ (1 − margin) = R120,000 ÷ 0.60 = R200,000. Gross profit at that price is R80,000, the buffer the firm needs for the months between engagements. If the same consultant had set price by adding "40% on cost" instead — a classic markup-versus-margin error — the price would have been R168,000 and gross profit only R48,000, a 40% loss of buffer on the identical brief.

What if the target margin moves to 50%? Selling price climbs to R240,000 (R120,000 ÷ 0.50) with R120,000 of gross profit — a 50% increase in selling price relative to 40% margin, and 50% more buffer. The lever to test is whether the client market will bear the higher number. Consulting margins of 35–55% are typical internationally; below 30% rarely covers the cost of carrying a lumpy pipeline.

Frequently Asked Questions

How do I calculate the selling price from cost and margin?

Selling Price = Cost ÷ (1 − Desired Margin). This formula is used when you know your cost and the profit margin percentage you want to achieve. Example: cost $50, target margin 40% → Selling Price = $50 ÷ 0.60 = $83.33.

What is cost-plus pricing?

Cost-plus pricing means setting your price by adding a fixed markup to your cost. It is the simplest pricing method: know your cost, add your desired profit, and that is your price. The risk is that it ignores what the market will actually pay.

How do I price a service (not a product)?

For services, "cost" includes your time at a target hourly rate plus any direct expenses. Use the Freelance Rate Calculator to determine your minimum hourly rate, then use this tool to set project prices that achieve your target margin.

Should I include VAT/sales tax in my advertised price?

In the UK, consumer-facing prices must be displayed inclusive of VAT. In the USA, sales tax is typically added at checkout and not included in advertised prices. In South Africa, prices are generally displayed inclusive of VAT. This calculator handles all three conventions.

How does pricing affect profit margin?

A small price increase has a disproportionately large effect on margin. If your cost is $50 and you sell at $70 (30% margin), a $5 price increase to $75 raises your margin to 33.3% — a 10% improvement in profitability from a 7% price increase.

How does VAT registration in the UK or SA change my pricing?

Once you cross the VAT threshold (£90,000 turnover in the UK, R1 million in South Africa) you must add VAT to every invoice. If your customers are consumers, this effectively cuts your margin by 17–20% unless you raise prices. B2B customers usually reclaim VAT, so the impact is neutral. Plan the transition before you cross the threshold, not after.

What is the most common pricing mistake?

Pricing based on what feels reasonable rather than on cost plus target margin. Owners often anchor to a competitor's price without knowing whether the competitor is profitable, or set a round number ($99) that looks tidy but does not cover allocated overhead. Run every price through the calculator first; treat market and psychological pricing as adjustments, not the starting point.

What if my target margin is 100% or more?

A 100% margin is mathematically impossible — you would need to sell something for an infinite price (the formula divides by zero). The maximum sensible target is around 90%. If you genuinely want a very high margin, switch to markup-based pricing instead, where 1000% markup is well-defined and equals a 90.9% margin. The calculator caps margin entries at 99% for this reason.

I have my recommended price — should I just publish it?

Sanity-check it against three things first. One: competitor prices within your category — if you are 30%+ above or below the band, you need a story for why. Two: psychological price points ($49 vs $50, £99 vs £100). Three: round-up to absorb future cost rises. If the calculator says $73.14, publishing at $79 gives you headroom and looks deliberate rather than algorithmic.

How is pricing different from quoting?

Pricing sets a standard selling price for a repeatable product or service, designed to hit a target margin across many sales. Quoting is custom — it builds a one-off price for a specific client and scope, often including line items the standard price does not cover (travel, rush work, exclusivity). Use this calculator for pricing; quoting needs an itemised estimate template instead.

Glossary

Target Margin: The gross margin you want each sale to earn, expressed as a percentage of selling price. Drives the price-from-margin formula.
Cost-Plus Pricing: Setting price by adding a fixed margin or markup on top of internal cost. Simple and defensible, but ignores what the customer is willing to pay.
Value-Based Pricing: Setting price from the value the customer perceives rather than internal cost. Usually delivers higher margins when the value is clearly quantifiable.
Psychological Price Point: A round-up to a price ending in 9 or 5 that anchors better with buyers than the raw calculator output. Worth a small premium over the mathematical answer.
