SaaS Unit Economics Calculator ఎందుకు ఉపయోగించాలి
Growth is useful only when the economics behind each customer make sense. A high LTV/CAC ratio suggests acquisition can scale profitably. A long CAC payback period means cash is locked for too long before the customer repays acquisition cost. This calculator gives founders and operators a quick read on both metrics.

ఉదాహరణ
B2B SaaS example
A product has Rs 2,000 ARPU, 80 percent gross margin, 3 percent monthly churn and Rs 8,000 CAC.
- Gross profit
- Rs 1,600 per month
- LTV
- About Rs 53,333
- LTV/CAC
- About 6.7x
- CAC payback
- 5 months
అనుమానాలు మరియు పరిమితులు
- LTV is calculated as monthly gross profit divided by monthly churn.
- The calculator does not model expansion revenue, contraction, discounting or cohort-specific retention curves.
- Use consistent customer definitions across ARPU, churn and CAC.
తరచుగా అడిగే ప్రశ్నలు
What is a good LTV/CAC ratio?
Many SaaS teams look for 3x or higher, but the right benchmark depends on market, retention, gross margin and sales cycle.
What is CAC payback?
CAC payback is the number of months needed to recover customer acquisition cost from gross profit generated by that customer.
Should I use revenue or gross profit for LTV?
Gross profit is usually better because hosting, support and delivery costs reduce the value of revenue.
Does this include expansion revenue?
No. This is a simple steady-state model. Expansion revenue should be added in a more detailed cohort model.
చివరి మాట
Use the SaaS unit economics calculator before scaling paid acquisition or sales hiring. Healthy growth needs both strong LTV/CAC and a CAC payback period that the company's cash balance can support.
