How It Works
This calculator breaks down the cost of each handloaded round from its individual components: primer, powder, bullet, and brass. It then compares your reloading cost to factory ammunition prices.
The basic rule:
- Primer cost = price per 1,000 ÷ 1,000
- Powder cost = (charge in grains ÷ 7,000) × price per pound
- Bullet cost = box price ÷ bullets per box
- Brass cost = price per case ÷ number of reloads before discard
Total cost per round is the sum of all four components. The break-even calculation tells you how many rounds you need to reload before your equipment investment pays for itself through savings versus factory ammo.
Tips & Considerations
- Double-check your primer cost before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both cost per round and cost per round — they work together to give you the full picture.
- Bookmark this page for quick access next time you need to get accurate results.
- If you're unsure about your equipment investment, start with a conservative estimate and adjust from there.
Frequently Asked Questions
Is reloading ammunition cheaper than buying factory ammo?
In most cases, yes. Reloading typically saves 30-60% per round compared to factory ammo, depending on the caliber and components used. The savings are most significant for larger or premium calibers like .300 Win Mag or 6.5 Creedmoor.
How many times can I reload brass?
Most rifle brass can be reloaded 5-10 times, and pistol brass can go 10-20+ times depending on the cartridge and pressure levels. Signs of worn brass include split necks, loose primer pockets, and head separation marks.
How many grains of powder are in a pound?
There are 7,000 grains in one pound of powder. So a typical .308 Win load using 42 grains per round yields about 166 rounds per pound of powder.
What equipment do I need to start reloading?
At minimum you need a reloading press, dies for your caliber, a powder scale, a powder measure, a case trimmer, and a reloading manual. A quality single-stage press setup typically costs $300-600. Progressive presses for higher volume cost $500-1,500.
How long does it take to break even on reloading equipment?
With a $500 equipment investment and savings of $0.50 per round, you'd break even after reloading 1,000 rounds. Most active shooters recoup their investment within the first year. High-volume shooters break even much faster.
Does this calculator include the cost of reloading time?
No, this calculator covers component costs only. An experienced reloader on a single-stage press produces about 50-100 rounds per hour. Progressive presses can produce 200-500+ rounds per hour. Whether your time factors in is a personal decision.
