Seven free ammo calculators and charts, all in the page, none of them gated. Between them they answer what a round really costs, whether reloading pays for itself, how hard a cartridge kicks, and what the market is doing this month.
The recoil chart is worked from SAAMI’s own formula, with every input shown.
| Tool | The question it answers | What you get |
|---|---|---|
| Cost Per Round Calculator | What am I really paying a round? | Box price with shipping and tax worked in, so two listings can be compared honestly. |
| Reloading Cost Calculator | Does reloading pay for itself? | Component cost per round, plus how many rounds it takes to earn back the press and dies. |
| Caliber Comparison Chart | How do these cartridges compare? | Bullet size, velocity and energy side by side for the common calibers. |
| Rifle Caliber Chart | What do these actually look like? | Twenty-six cartridges drawn to scale, so the size difference is visible rather than described. |
| Rifle Recoil Chart | How hard does it kick? | Recoil energy and velocity worked from the SAAMI formula, with rifle weight, charge and bullet weight all shown. |
| Ammo Shortage Tracker | Is there a shortage, and what does it cost today? | Live per-round prices across common cartridges, background check data and the tariff picture. |
| Ammo Price History | Are prices going up, and is now a bad time to buy? | Fifty years of federal price data beside today’s price per round for twenty cartridges, with a picker that scales any of them to your order. |
Which ammo calculator do you need
You are standing in front of two boxes and the prices are not comparable. One is cheaper a box but ships free, the other is cheaper a round before shipping. The cost per round calculator settles it, because it puts shipping and tax into the per-round figure instead of leaving them out.
You are wondering whether to start reloading. The reloading cost calculator gives you the component cost a round, then tells you how many rounds you have to load before the press, dies and tumbler have paid for themselves. For most shooters the honest answer is a bigger number than they expect, and the tool says so rather than selling you a hobby.
You are choosing between cartridges for a new rifle. Use two tools together. The caliber comparison chart puts bullet size, velocity and energy side by side. The recoil chart tells you what that performance costs your shoulder, which is the half of the decision most charts leave out.
You want to know if a cartridge is worth its reputation. The rifle caliber chart draws twenty-six of them to scale. A lot of arguments end quietly once the cartridges are the right size next to each other.
You are trying to work out whether to buy now or wait. The ammo shortage tracker carries live per-round prices, federal background check volume and the tariff position. It is the only one of these that changes week to week.
What these ammo calculators are built on
Every figure on these pages comes from a named source, and the arithmetic is shown rather than hidden. The recoil numbers are worked from the formula the Sporting Arms and Ammunition Manufacturers’ Institute publishes, with rifle weight, powder charge and bullet weight all visible, so a reader who disagrees with a result can see exactly which input to change. The cartridge drawings are scaled from published overall lengths, not sketched to look right. Prices in the tracker come from live retailer listings rather than a manufacturer’s suggested figure, because the suggested figure has not matched the shelf for years.
Where a number is a judgment rather than a measurement, the page says so in the same place the number appears. That happens more often than most reference sites admit. Component costs vary by supplier and by the day. Felt recoil is not the same thing as calculated recoil energy. A break-even point for reloading assumes your time is free, which it is not. None of that makes the tools less useful, but it does mean the honest version of each answer carries a qualification, and the qualification stays on the page instead of being quietly dropped to make the result look cleaner.
All six run entirely in the page you are reading. Nothing is sent to a server, nothing is stored about you, and no result is held back behind an email form. If a tool cannot answer a question honestly with the data it has, it says so rather than producing a confident number.
How these are kept current
Each tool carries its own updated date. When a figure, a price or a law changes, the page is corrected in place rather than republished at a new address, so a link you save keeps working and keeps being right.

Questions and answers
Do I need an account?
No. Every tool runs in the page with no email gate.
Where do the prices come from?
Live retailer listings rather than a manufacturer figure. The tracker page names its sources and carries its own updated date.
Is the recoil figure the same as felt recoil?
No. The chart gives calculated recoil energy, which is physics. Felt recoil also depends on stock fit, recoil pad and muzzle device, and the page explains the difference.
Can I embed a chart?
Yes. The caliber and recoil charts have an embed link under them.
Why is there both a caliber comparison chart and a rifle caliber chart?
They answer different questions. The comparison chart is numbers — size, velocity, energy. The caliber chart is a picture, drawn to scale. People ask both questions and they are rarely the same person on the same day.
Do the calculators keep my numbers?
Only in the web address, so you can bookmark a result or send it to someone. Nothing is stored about you and nothing is sent anywhere.
