Question 1

What is the Pew Pew Price Index (PPPI)?

Accepted Answer

The PPPI is a composite ammunition market score from 0 to 100, computed hourly from live deal data across 45+ US retailers. A score of 0 means ammo prices are at their lowest observed levels (strong buy). A score of 50 means prices are at the 90-day rolling average. A score of 100 means prices are at their highest observed levels (wait for prices to drop).

Question 2

How is the PPPI score calculated?

Accepted Answer

We compute the current average cost-per-round (CPR) for each tracked caliber (9mm, 5.56 NATO, .308 Win, .22 LR, etc.) and compare it to the 90-day rolling average CPR. The ratio is mapped to a 0-100 scale, then weighted by market volume (9mm = 30%, 5.56 = 25%, etc.) to produce a single composite score. See our /methodology page for full details.

Question 3

How often is the PPPI updated?

Accepted Answer

The PPPI API endpoint updates every hour, and the page is re-rendered on the same cadence via ISR. The underlying deal data is scraped from 45+ retailers every 60 minutes, so the index always reflects the most current market conditions.
