5.00x is the example result. Read it using the units and relationship stated below.
LTV:CAC uses customer lifetime value, customer acquisition cost.
Comparing financial amounts on a defined basis
For ltv:cac, the relationship is Result = (([Customer lifetime value]) ÷ ([Customer acquisition cost])). The amount depends on the supplied customer lifetime value, customer acquisition cost, rather than a live market price or a value imported from another record. A financial model is useful when its cash amounts, rate convention and time horizon describe the same case. Interest, return and purchasing power are different outputs. A projection should remain separate from an observed or audited balance.
What the model includes
Result = (([Customer lifetime value]) ÷ ([Customer acquisition cost])) Check whether a rate is annual, monthly, simple or compounded. Enter fees only where the form represents them and identify contractual charges that remain outside the estimate. A monthly payment alone does not establish affordability or total ownership cost. Use the result to prepare the next question about terms or assumptions. Tax treatment, lender conditions and valuation evidence require the relevant source documents; they cannot be recovered from a few numeric inputs.
Example with the supplied inputs
Customer lifetime value: 5000; Customer acquisition cost: 1000. Result: 5.00x. The values are illustrative.
Compare one changed input
Customer lifetime value changes from 5000 to 5500. The result becomes 5.50x. All other inputs remain fixed.
Calculation rule
Result = (([Customer lifetime value]) ÷ ([Customer acquisition cost]))
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Customer lifetime value | 5000 | Use the source quantity represented by customer lifetime value. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Customer acquisition cost | 1000 | Use customer acquisition cost on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate. |
Output: 5.00x is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Customer lifetime value, Customer acquisition cost. Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Customer lifetime value on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 5.00x.
Change Customer lifetime value from 5000 to 5500 while keeping every other value fixed. The result becomes 5.50x. This comparison isolates that input; it does not forecast how other variables will respond.
Check the stated formula, units and limits before using the result in a decision.
