What is cost per round (CPR)?

Cost per round (CPR) is calculated by dividing the total price of ammunition by the number of rounds in the box or case. For example, a 1000-round case of 9mm at $190 has a CPR of $0.19/rd. DOPE extracts round counts from product names and calculates CPR automatically across 20+ verified retailers.

Ammunition Price Tracker — Live Cost Per Round Data

DOPE's Ammo Tracker provides Bloomberg-style cost-per-round (CPR) intelligence across 27 calibers from 19 major retailers. Track real-time ammo prices for 9mm, .223/5.56, .308, .45 ACP, .22 LR, .380 ACP, 10mm, 7.62x39, 6.5 Creedmoor, .300 Blackout, .30-06, .270 Win, .357 Magnum, .44 Magnum, 5.7x28mm, .338 Lapua, .50 BMG, 12 gauge, 20 gauge, .410 bore, and more.

Every price is calculated as CPR (cost per round) by extracting the round count from each product listing and dividing by the sale price. We filter out reloading components, ammo storage boxes, and accessories — only loaded ammunition with verified round counts makes it into our tracker.

How DOPE Scores Work

Each caliber gets a D.O.P.E. Score from 0-100 based on three factors: availability (40%), price versus 90-day average (40%), and retailer count (20%). Green scores (70+) mean it's a good time to buy. Amber (40-70) is average. Red (below 40) means prices are high or stock is low.
