What this means

Growth efficiency looks healthy

Your LTV to CAC ratio is not below the planning range we use for retail store

At your current inputs, each acquired customer produces about $331 in gross-profit lifetime value for every $50 of CAC.

That is a 6.62x ratio with payback in about 4.5 months.

Want help improving this number?

If the ratio is weak, growth is usually outrunning retention, pricing, or gross profit. That is where the next operational fix belongs.

Calculator guide

How to use this LTV:CAC calculator

This calculator compares gross-profit lifetime value with CAC, then shows whether growth economics look healthy enough to scale.

Why the ratio matters

A business can have a good LTV and still have weak growth economics if CAC eats too much of it.

The ratio helps you see how much gross profit is left after paying to win the customer.

What a weak ratio means

A weak ratio usually means one of three problems: CAC is too high, retention is too weak, or gross margin is too thin.

The right fix depends on which of those three is really causing the damage.
