# Ecommerce LTV (Customer Lifetime Value)

Customer Lifetime Value (CLV or LTV) is a key performance indicator (KPI) that measures the total revenue a business can expect from a single customer throughout their relationship with the brand. Understanding LTV helps businesses make informed decisions about marketing expenditures and customer retention strategies.

## Importance of LTV

- **Allocating Resources**: Knowing the LTV helps allocate marketing budgets efficiently.
- **Customer Segmentation**: Identifies high-value customers and segments them for targeted strategies.
- **Investment Decisions**: Aids in making informed investments regarding acquisition costs and retention strategies.

## Calculating LTV

The standard formula for calculating LTV is:

\[ LTV = (Average Purchase Value) \times (Average Purchase Frequency) \times (Customer Lifespan) \]\

Where:
- **Average Purchase Value**: Total revenue divided by the number of purchases.
- **Average Purchase Frequency**: Number of purchases per customer over a defined period.
- **Customer Lifespan**: Average time a customer continues to purchase from your company.

## Factors Affecting LTV

- **Customer Retention**: Higher retention rates lead to longer customer lifespans.
- **Upselling/Cross-selling**: Increasing the average purchase value.
- **Churn Rate**: Reducing the rate at which customers stop purchasing.
