### Incremental Value

Let's say I want to move 13-24 month 1x buyers to a second purchase.

How much might I be able to spend to make this happen?

In our table, the average 13-24 month 1x buyer is worth about \$13.50.

In our table, the average 0-12 month 2x buyer is worth about \$71.65.

Intuitively, you might say that you gain \$58 of value, so you can spend a fortune.

Nope.

There are two things we need to know.
• Actual repurchase rate of 13-24 month 1x buyers.
• Incremental percentage that we will convert with incremental marketing activities.
• Percentage of demand that flows-through to profit.
Let's pretend that the annual repurchase rate of 13-24 month 1x buyers is 10%. Let's also pretend that we can increase the 10% annual repurchase rate to 12% by performing various marketing activities. Finally, let's assume that 35% of demand flows-through to profit. We now have the pieces necessary to determine how much we can invest.

Look at the "Marketing Cost" line ... you could invest an additional \$0.77 per customer, and if you can achieve a 20% increase in repurchase rate, the math yields more profit.

This is how a modern marketer can leverage lifetime value style metrics to improve business performance. In our example (assuming that we can truly get a 20% increase in repurchase rates by marketing more to a customer), we are able to grow the active 2x buyer file - and that's a good thing, right? These customers will spend a ton of demand next year.
