Example: https://askcalculators.com/ie/ltv/?monthlyRevenue=100&grossMargin=80&monthlyChurn=3&monthlyDiscount=1&months=60

## Inputs
- monthlyRevenue: Monthly revenue per active customer; type=money; required; default=100; min=0; max=1000000000000
- grossMargin: Contribution gross margin; type=percent; required; default=80; min=0; max=100
- monthlyChurn: Monthly logo churn probability; type=percent; required; default=3; min=0; max=100
- monthlyDiscount: Monthly discount rate; type=percent; required; default=1; min=0; max=50
- months: Finite projection horizon, months; type=number; required; default=60; min=1; max=1200

## Outputs
- monthlyContribution: Monthly contribution per retained customer; format=currency
- steadyLtv: Undiscounted infinite-horizon contribution LTV; format=currency
- discountedLtv: Finite-horizon discounted contribution LTV; format=currency; primary

## Formula
finite LTV = sum from month 1 to horizon of contribution × (1 − churn)^(month − 1)/(1 + monthly discount)^month.

Inputs are converted to canonical units before evaluating this stated formula.

## Rules
- Empty optional inputs are undefined, not zero.
- Hidden conditional inputs are ignored.
- Do not invent missing required inputs.
