One-time purchase · yours to keep · runs in any browser · your data never leaves your device
Before you pour money into growth, you need to know one thing: does each customer make you more than they cost to win? UnitEconomics answers it in the four numbers investors and lenders ask for first — CAC, LTV, the LTV:CAC ratio, and how many months it takes to earn back what you spent acquiring a customer.
Enter your revenue per customer, gross margin, retention and acquisition spend, and it does the math live — then tells you in plain English whether your economics are healthy (push harder), thin (fix before you scale), or upside-down (stop and fix now). It's the difference between scaling a machine and scaling a leak.

Use an estimate, or switch to average customer lifespan in months — the tool takes either.
One-time purchase, yours to keep. Founding pricing — lock it in before it moves.
