Subscription Pricing Calculator

Find the minimum monthly price needed to achieve your target LTV:CAC ratio โ€” and see the gross margin impact of your pricing decisions.

Pricing is the most powerful lever in SaaS โ€” a 10% price increase flows almost entirely to profit, while a 10% customer increase still incurs full CAC. This calculator reverse-engineers the minimum ARPU you need given your CAC, gross margin, churn rate, and target LTV:CAC ratio. It answers: "Are we charging enough?"

The Formula

Required ARPU = (CAC ร— Target LTV:CAC) รท Gross Margin รท (1 รท Monthly Churn)

In plain English

Calculate required GM LTV as CAC ร— target ratio. Divide by gross margin to get required simple LTV. Divide by average customer lifespan (1 รท churn rate) to get required monthly ARPU.

Worked Example

CAC: $2,500. Target 3:1. GM: 75%. Churn: 2%/mo (50mo life). Required GM LTV = $7,500. Simple LTV = $10,000. ARPU = $10,000 รท 50 = $200/mo.

Pricing Is the Highest-Leverage SaaS Decision

A 10% price increase flows almost entirely to profit โ€” because COGS doesn't increase, sales headcount doesn't increase, and R&D doesn't increase. By contrast, a 10% increase in customers requires proportionally more CAC, support, and infrastructure.

Most SaaS companies are underpriced. Research consistently shows that 80% of SaaS companies have not raised prices in over a year, yet their value delivered to customers has increased through feature additions, reliability improvements, and support quality.

Willingness to Pay vs Cost-Plus Pricing

Never set SaaS prices based on cost-plus (costs + desired margin). Set them based on willingness to pay โ€” what value does your product create for the customer? A tool that saves a $100K/year employee 2 hours per day creates $25K/year in value. Charging $200/month ($2,400/year) for that is a 10ร— value-to-price ratio โ€” room to increase.

How to Increase ARPU Without Losing Customers

Price increase strategies: (1) Grandfathering โ€” raise prices for new customers only, honour existing. (2) Value metric expansion โ€” shift from flat to per-seat, per-API-call, or per-outcome. (3) New tier โ€” add a higher tier with premium features at 2โ€“3ร— the current highest price. (4) Annual upfront discount โ€” convert monthly to annual at 10โ€“20% discount, boosting LTV.

The fear of churn from price increases is almost always overstated. Research shows that most SaaS price increases of 15โ€“25% cause less than 5% churn โ€” meaning the revenue impact is strongly positive.

Common Mistakes

โš ๏ธ

Setting price based on cost plus margin instead of value delivered

Cost-plus pricing leaves enormous money on the table. If your tool saves customers $10,000/month, charging $200/month is a 50ร— value ratio โ€” far below what the market will bear. Always anchor pricing to value created, not cost incurred.

โš ๏ธ

Keeping prices flat while product value increases

Every new feature, reliability improvement, and integration you ship increases the value your product delivers. Not raising prices annually is effectively a price cut โ€” inflation erodes margins, and increased value goes uncaptured. Annual price reviews are a standard practice at mature SaaS companies.

โš ๏ธ

Using a single price for very different customer segments

A flat price is wrong for everyone: too high for small customers, far too low for large ones. Tiered pricing by company size, usage level, or feature set captures more value from large customers while staying accessible to smaller ones.
