How this service works
MRR, ARR, customer lifetime, annualised churn and LTV from customers, ARPU and monthly churn, with optional CAC payback.
Output
Returns a JSON object containing MRR, ARR, average lifetime in months, annualised churn percentage, LTV, and optionally LTV:CAC ratio and CAC payback months. Also includes a summary, verdict, and disclaimer fields, plus a degraded flag and reasons array if any inputs caused partial computation.
Example use cases
Investor deck SaaS metrics snapshot
“I'm preparing a pitch deck — we have 1,200 subscribers, $89/month ARPU, 1.8% monthly churn, $350 CAC, and 80% gross margin. Can you work out our MRR, ARR, LTV, LTV:CAC, and how many months to pay back CAC?”
Evaluating churn impact on lifetime value
“Our monthly churn just jumped from 3% to 5% and our ARPU is $50 with 600 customers. What does that do to our LTV and annualised churn, assuming 70% gross margin?”
Bootstrapped SaaS unit economics check
“I've got 200 customers paying $199/month on average, with 1.2% monthly churn and no external CAC since we're bootstrapped. What are my MRR, ARR, average customer lifetime, and LTV?”
Technical details
Endpoint
GEThttps://pricing-math.x402tookit.com/subscription?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need standard SaaS subscription metrics — MRR, ARR, LTV, churn conversion, and CAC payback — computed correctly and instantly without writing formulas yourself. Ideal for investor reporting, unit economics checks, and scenario modelling where inputs are customer count, ARPU, and monthly churn. Prefer this over generic calculators when you also need LTV:CAC and CAC payback in the same response.
Side effects
- Missing required parameters (customers, arpu, or monthlyChurnPct) returns a 400-level error
- monthlyChurnPct of 0 or negative is invalid and will be rejected
- Extremely high churn (approaching 100%) may produce near-zero lifetime values
- CAC payback and LTV:CAC are omitted from the response if cac is not supplied
- grossMarginPct defaults to 100 if not provided, which may overstate LTV for low-margin businesses
