Pricing methods — formulas and examples

Pricing method Formula Example (cost = £60)
Target margin (recommended) Price = Cost / (1 − Margin%) 40% margin → £60/0.60 = £100
Cost-plus markup Price = Cost × (1 + Markup%) 40% markup → £60×1.40 = £84 (28.6% margin)
Keystone pricing Price = Cost × 2 (100% markup) £60×2 = £120 (50% margin)
Competitive pricing Match or undercut market price Market £110 → Price £105 (43% margin on £60 cost)
Value-based pricing Price = Perceived customer value Outcome worth £500 → Price £300–£400 (regardless of cost)

Frequently asked questions

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

Selling Price = Cost / (1 − Target Margin %). Example: 40% margin on £60 cost → £60/0.60 = £100. Common mistake: adding the % to cost → £60 + 40% = £84 gives only 28.6% margin. Always divide, don't add. The division formula is the only way to guarantee a specific margin percentage.

What is the difference between cost-plus and value-based pricing?

Cost-plus: start from cost, add markup/margin → guarantees profit but may price too low if clients would pay more. Value-based: start from customer value, work backwards → typically higher prices and margins, requires customer research. Recommendation: calculate minimum viable price (cost-plus) then price towards value-based where the market allows.

How should freelancers calculate their day rate?

Formula: (Income target + Business costs) / Billable days. Example: £50k after-tax income → ~£70k gross; £5k business costs → total needed £75k. Billable days: 220 × 60% utilisation = 132 days. Day rate = £75k / 132 = £568/day. Always round up — easier to negotiate down than raise your rate.

What happens if I price too low?

Under-pricing leads to: thin margins with no buffer for unexpected costs; quality perception issues (low price signals low quality); scope creep (low-paying clients demand more); no money to invest in growth; attracting price-sensitive clients who leave for cheaper alternatives. Fix: calculate your true minimum price, research market rates, then move up towards value-based pricing.
