Shooting calculators

Eight calculators for USPSA, IDPA and Steel Challenge: what class your scores put you in, what a stage scored as a hit factor, whether a load makes major or minor, where your times sit, and what a season costs. Each runs in your browser and nothing you type leaves it.

Your calculator entries are remembered only in your own browser — no number you enter into these calculators is ever sent anywhere. Two things at the foot of this page DO send what you put in them, because that is what they are for: the “Spot a mistake?” box sends your message and, if you add one, your email address; the launch-list box sends your email address. What happens to either is on the privacy page.

Every calculator

USPSA classification calculator

What class your classifier percentages put you in, and the score you need on the next classifier to move up. Shows both readings of USPSA’s window where they disagree about your class.

IDPA classification calculator

Your IDPA class from a classifier score — for all three of the classifiers IDPA runs at once, each with its own table of times — and the seconds that have to come off to reach the next class.

Steel Challenge classification calculator

Your SCSA percentage and class from your best stage times — and the seconds that have to come off to reach the next class.

Hit factor calculator

Points, penalties, net score and hit factor for a USPSA stage, at major or minor — plus what the same run scores with every hit an A.

Power factor calculator

Bullet weight × velocity ÷ 1000, and which side of the major/minor line it lands on.

Where do my times sit?

Enter your times. It shows the skill band each one falls in. These are approximate community/coaching benchmarks — not an official USPSA class (that's earned only by classifier scores). Building these numbers is what a dry-fire routine is for.

Draw to 1st shot, 7 yd (sec)

Reload, in position (sec)

Split, close target (sec)

Draw · reload · split band—

Interpolated from published drill benchmarks — Ben Stoeger's and Steve Anderson's dry-fire books — and classics like the Bill Drill. The bands run GM down to C, with “keep building” below that — a gut-check on your mechanics, never a verdict on your class.

FirearmLog logs every draw, reload, and split, so you watch these trend toward the next band. Log yours in the web app →

The true cost of competing

The all-in number for a year — practice ammo, match fees, travel, and your range. (No vendors, no links — just your own figures. Match-day rounds aren't broken out separately, so fold them into your weekly practice figure.)

Practice rounds / week

Cost per round ($)

Matches / year

Avg match fee ($)

Round-trip miles / match

Cost per mile ($)

Other travel / match ($)

Range / dues per month ($)

Per month · per year—

Ammo, match fees, travel, and range — added once each.

FirearmLog tracks each of these once, so nothing double-counts. Log yours in the web app →

Spot a mistake?

Rules change and pages fall behind. I keep these as current as I can — if something here doesn't match the rulebook you're holding, tell me and I'll fix it.
