How Should You Price a SaaS Product?

SaaS pricing has a floor and a ceiling. The floor is set by your costs: price must cover what it costs to serve a customer, with enough gross margin left to fund acquisition, development, and eventually profit. The ceiling is set by value: what the problem costs your customer, and what alternatives charge. This calculator nails down the floor precisely — minimum viable price for your margin target — and sanity-checks your proposed price against it, so you never publish a pricing page that loses money by design.

The Formula Behind It

The division trips people up: to hit an 80% margin on an $8 cost to serve, the minimum price is $8 ÷ 0.20 = $40, not $8 × 1.8 = $14.40. Margin is measured against price, not cost — confusing margin with markup is the most common pricing spreadsheet error, and it always errs toward underpricing.

What Counts as Cost to Serve?

Everything that scales with one more customer: hosting and infrastructure share, third-party API costs (including any AI model calls — check them with our LLM API cost calculator), payment processing fees (typically ~3%), support time, and per-seat licences for tools you resell. It excludes fixed costs like salaries for product development and your own customer acquisition cost — those are funded out of gross margin, which is precisely why the margin must be large.

Why SaaS Needs 70–85% Gross Margin

• Public SaaS companies average roughly 75% gross margin; investors treat below 70% as a flag and below 50% as a broken model
• Gross margin funds everything else: sales and marketing (often 30–50% of revenue in growth mode), R&D (15–25%), and G&A
• Margin also multiplies through your unit economics — it sits inside both LTV and CAC payback, so a margin improvement strengthens both simultaneously
• Heavy-compute products (AI, video, data processing) run structurally lower margins — which is exactly why they must price higher relative to raw cost, not lower

How to Use This Calculator

Enter your per-customer monthly cost to serve, your target gross margin (80% is a sound default), and the monthly price you're considering. The calculator returns the minimum price your target demands, the actual margin at your proposed price, gross profit per customer, and — with an expected customer count — projected MRR and ARR. Add your CAC to see payback at that price, graded against the 12-month benchmark. Then test price increases: rerun at $59 instead of $49 and watch what it does to payback and ARR.

Worked Example

A founder's product costs $8/month per customer to serve (hosting, APIs, payment fees, support share). Targeting 80% margin, the minimum price is $8 ÷ 0.20 = $40/month. Their proposed $49 price yields an 83.7% margin and $41 monthly gross profit — healthy. With 200 expected customers, that's $9,800 MRR / $117,600 ARR, and a $400 CAC pays back in 9.8 months, inside benchmark. Had they priced at $19 "to be competitive," margin would be 57.9% and CAC payback 36 months — a slow-motion failure that looks fine on launch day.

Beyond the Floor: Pricing Strategy Basics

• Value-based beats cost-plus: once the floor is cleared, price against the value delivered and the alternatives' cost, not your own costs
• Three tiers work: a decoy entry tier, the target middle tier most buyers choose, and a premium tier that anchors the middle as reasonable
• Charge on a value metric: per seat, per 1,000 contacts, per GB — a unit that grows as the customer gets more value grows revenue without repricing
• Annual billing at a discount: 15–20% off for annual prepay improves cash flow and cuts churn substantially
• Raise prices more often than feels comfortable: underpricing is the default SaaS error, and grandfathering existing customers makes increases low-risk

Where This Fits Your Numbers

Price flows through everything: it sets the gross profit that determines CAC payback, scales your LTV, and shifts your break-even point. After settling a price here, run those three with the new figure — a $10 price change often moves break-even by months and LTV by hundreds of dollars.
