Pricing Model Calculator
Most people price by gut, by what competitors charge, or by marking up cost by an arbitrary percentage. The Pricing Model Calculator builds the floor and ceiling from real unit economics, runs the price-volume-profit matrix, checks LTV:CAC against benchmarks, and tells you where in the range to land.
What this skill does
Pricing is the highest-leverage decision in business. A 1% price improvement drops straight to the bottom line, often with more impact than 1% more volume or 1% lower cost. Yet most businesses price by mark-up on cost, copying competitors, or by what felt right last year. This skill replaces that with a structured model — floor, ceiling, three strategies, sensitivity matrix, and the customer-lifetime economics that determine whether the business actually works.
Floor and ceiling come first. The floor is variable cost plus allocated fixed cost plus minimum margin to sustain operations — below this, you lose money on every sale. The ceiling is the value-based maximum (typically 10-30% of the quantifiable value delivered to the customer), the competitive ceiling, or the historical willingness-to-pay, whichever applies. The price-setting decision is finding the right point in the range between them — not picking a number and hoping.
Three strategies get modelled side by side. Cost-plus suits commodity products and wholesale. Value-based suits B2B and differentiated offers where the customer's saving or earning is quantifiable. Competitive positioning suits established markets with a clear leader, average, and budget option. Each strategy produces a recommended price, a breakeven volume, and the trade-offs it implies. The skill picks one as the lead recommendation and explains why the other two were rejected.
LTV:CAC is the master metric. Below 3:1 means the pricing or the retention is broken — and the skill flags which. 3:1 to 5:1 is healthy. Above 5:1 often means you're underpricing or under-investing in growth. Structure matters too: monthly versus annual gets modelled with the cash flow and churn implications, tiered pricing checks that no more than 60% of customers land on the cheapest tier (otherwise the structure is wrong), freemium models the conversion rate needed to sustain the free tier costs, and per-seat models the expansion revenue from growing accounts.
You get the recommended price with strategy and rationale, the full unit economics table, a sensitivity analysis showing profit (not just revenue) at three price points, a structure comparison if multiple structures apply, the LTV:CAC verdict against benchmarks, a migration plan for existing customers if a rise is proposed (with grandfather period, annual lock-in incentive, and the modelled churn impact), and a testing plan because pricing is a hypothesis until validated. The skill anchors high — research consistently shows starting high and discounting outperforms starting low and trying to raise, so the first number always sets the frame.
When this triggers
- ·You're setting price on a new offer and don't want to guess
- ·You're considering a price rise on existing customers and need to model churn impact vs revenue lift
- ·Your LTV:CAC feels off and you suspect the pricing — not the funnel — is the cause
- ·You're choosing between monthly, annual, tiered, freemium, or per-seat structures
- ·A competitor moved their price and you want a structured response rather than a panic match
Example
Trigger
User: 'Selling a B2B reporting tool. Variable cost £4/customer/month. Fixed £18K/mo. 240 customers at £39/mo. CAC £180, average tenure 14 months. Competitor charges £49. Should I raise?'
Output
Pricing Recommendation Recommended price: £49/month (matched to competitor) Strategy: Competitive — currently undercharging vs market Rationale: Current price below the value ceiling and below the nearest competitor. Floor is £79 contribution per year short of break-even on CAC at current tenure. Unit economics (current vs proposed) | Metric | Now | £49 price | £59 price | |------------------------|--------|-----------|-----------| | Variable cost/month | £4 | £4 | £4 | | Contribution margin | £35 (90%) | £45 | £55 | | Fixed cost cover (240) | 1.2x | 1.5x | 1.8x | | LTV (14mo tenure) | £490 | £630 | £770 | | LTV:CAC | 2.7:1 | 3.5:1 | 4.3:1 | | LTV:CAC verdict | Below benchmark | Healthy | Healthy | Sensitivity (price-volume-profit at 5% churn shock) | Price | Vol assumption | Revenue/mo | Profit/mo | |-------|----------------|------------|-----------| | £39 | 240 (now) | £9,360 | -£9,600 | | £49 | 228 (-5%) | £11,172 | -£7,740 | | £59 | 216 (-10%) | £12,744 | -£6,696 | Risks · 5-15% of price-sensitive customers may leave on increase · If competitor cuts to £39, your premium positioning weakens · Volume assumptions are model — actuals may differ Migration plan for existing 240 customers · 60-day grandfather at £39 · Annual lock-in at old price as switch incentive · Communicate value added since their original sign-up · Model assumes 10% churn on increase — net revenue +£1,400/mo
