Pricing is never finished

Your first price is a hypothesis. Markets, costs and your product evolve, so pricing should be reviewed and tested regularly.

Ways to test willingness to pay

MethodHowNotes
Customer interviewsAsk about current spending and budgets; show price rangesWords are weaker evidence than actions
Van Westendorp price sensitivity questionsAsk at what price the product is too cheap, cheap (a bargain), expensive, and too expensiveGives an acceptable range; survey-based
Landing page testsShow different prices to different visitors; measure sign-upsMust comply with consumer rules; be transparent at purchase
Pre-sales at a priceAsk for payment or depositsStrong evidence
Sales conversationsQuote different prices to comparable prospects; track win ratesCommon in B2B
Cohort price changesNew customers see a new price; compare conversion and retentionKeeps existing customers stable

Running a simple price test: step by step

  1. Define the question: e.g., "Will a price of 45 instead of 30 reduce conversion by more than a third?"
  2. Choose the metric: conversion rate, revenue per visitor, retention.
  3. Calculate the break-even conversion drop: at 45, you can lose up to a third of conversions and still earn the same revenue (30/45 = 0.67). Contribution break-even may differ because variable costs stay the same per customer.
  4. Run the test long enough to get a meaningful sample.
  5. Decide and monitor retention, not just initial conversion.
Illustrative results (per 1,000 visitors)
Price   Conversion   Customers   Revenue   Contribution (variable cost 6/customer)
30      4.0%         40          1,200     960
45      3.2%         32          1,440     1,248

Even with fewer customers, the higher price yields more revenue and contribution. Check that the customers acquired at the higher price retain as well.

Discounts: use with care

Discounts can drive trials, clear stock or reward loyalty, but they carry risks:

  • They train customers to wait for sales.
  • They attract price-sensitive customers who may churn quickly.
  • They reduce margin sharply. With a 40% contribution margin, a 20% discount halves contribution per unit: you need twice the volume to earn the same contribution.
Contribution margin 40% → price 100, variable cost 60, contribution 40
20% discount → price 80, variable cost 60, contribution 20
Volume needed to match original contribution: 40 / 20 = 2× original volume

Prefer targeted, time-limited, purposeful discounts: first-month offers to test a product, annual prepayment discounts that improve cash flow, or volume discounts that reflect lower cost to serve.

Raising prices

Price increases are often necessary as costs rise or value grows. To do it well:

  1. Improve or clarify value first (new features, better service).
  2. Give notice (often 30–60 days for subscriptions), explaining why.
  3. Consider grandfathering existing customers for a period.
  4. Offer options: annual lock-in at the current price, or a lower tier.
  5. Train customer-facing staff to handle questions.
  6. Monitor churn and feedback closely.

Always follow the terms in your customer contracts and consumer protection rules on price changes and auto-renewal notices.

Worked example

Illustrative. A software company in Riyadh had not raised prices in three years while adding many features. It announced a 20% increase for new customers immediately and for existing customers after 90 days, offering a 12-month lock-in at the old price for annual prepayment. Many customers chose annual prepayment, improving cash flow, and churn stayed within normal ranges.

2026 update: testing prices responsibly

Price experiments are easier than ever to run with modern checkout, billing and analytics tools, which makes it more important to run them fairly:

  • Be transparent at the point of purchase. Whatever price a customer sees is the price they pay, with required taxes and fees shown. In the UK, the Digital Markets, Competition and Consumers Act 2024 strengthened consumer-law enforcement, including against hidden or "drip" fees; other regulators, including the US FTC, have also acted on hidden fees. Check current rules where you sell.
  • Avoid personalised pricing based on sensitive characteristics, and be cautious with algorithmic or dynamic pricing: be able to explain why two customers saw different prices.
  • Prefer cohort tests over individual randomisation for B2B and small audiences: new customers in a period see the new price; existing customers are unaffected.
  • Watch retention, not just conversion. A higher price that attracts better-fit customers can lower conversion yet raise lifetime value.

Hands-on: price test planner and break-even calculator

PRICE TEST PLANNER
Question:          Will £45 (vs £30) reduce conversion by more than a third?
Current price:     £30        New price: £45
Variable cost:     £6 per customer per month
Revenue break-even conversion ratio  = old price / new price        = 30/45 = 0.67
Contribution break-even ratio        = (30-6) / (45-6) = 24/39      = 0.62
=> At £45 you can lose up to ~38% of conversions and still earn the same contribution.
Metric:            paid conversion, 60-day retention, contribution per visitor
Audience/cohort:   new visitors from organic search, 4 weeks
Minimum sample:    enough conversions per arm to see a difference (aim for dozens, not a handful)
Decision rule (set now): adopt £45 if contribution per visitor is higher AND 60-day
                   retention is not worse by more than 5 percentage points.
Compliance check:  [ ] price shown = price charged  [ ] taxes/fees visible  [ ] T&Cs updated

Hands-on: a price increase announcement (email script)

Subject: Changes to your [Product] plan from [date]

Hi [name],
Since you joined, we've added [2-3 concrete improvements tied to value they use].
To keep investing in [outcome they care about], the [plan] price will change from
[old] to [new] per [period] from [date, 30-60 days away].

What this means for you:
- Nothing changes until [date].
- If you prefer, you can lock in today's price for 12 months by switching to annual
  billing before [date].
- If a smaller plan suits you better, reply and we'll help you choose.

Thank you for being a customer. Any questions, just reply to this email.

Always follow your contract terms and applicable consumer rules on notice, auto-renewal and cancellation.

Common mistakes

  • Never testing price.
  • Measuring only conversion, not revenue, contribution and retention.
  • Blanket discounts to hit short-term targets.
  • Surprise price increases without notice or explanation.
  • Different customers discovering unexplained price differences, damaging trust.

Quick self-check

What would happen to your contribution if you raised prices 10% and lost 5% of customers? Calculate it. Many founders are surprised how favourable the result is.

Price and positioning

Remember that price signals quality and positioning. A price far below alternatives can make buyers suspicious, especially for professional services or products where trust matters. Aim for a price that reflects the value you deliver and the segment you want to attract, then back it with evidence and service.

Key takeaways

  • Treat price as a hypothesis; test with interviews, surveys, landing pages, pre-sales and cohorts.
  • Judge price tests on revenue, contribution and retention, not conversion alone.
  • Discounts cut contribution sharply; use them targeted, time-limited and purposeful.
  • Raise prices with added value, notice, options and compliance with contracts and consumer rules.
  • Calculate revenue and contribution break-even before a price test, set the decision rule in advance, and keep the price shown equal to the price charged.

Check your understanding

Quick questions to lock in the lesson. They don’t count towards your certificate.

  1. Contribution margin is 50% (price 100, variable cost 50). You offer a 25% discount. How much more volume do you need to keep the same total contribution?
  2. A price test increases revenue per visitor but new customers churn faster. What should you do?
  3. Which is a good practice when raising subscription prices?
  4. Price rises from £30 to £45 with a £6 variable cost per customer. Roughly what share of conversions could you lose and still earn the same contribution?

Put it into practice

Calculate the effect of a 10% price increase with 5% customer loss on your contribution, then design a price test with a pre-set success criterion.
