USPSA classification calculator
Your USPSA class is the class your classifier average falls in — D, C, B, A, Master or Grand Master — and that average is the best six of your eight most recent classifier percentages. Enter the percentages you have and this returns the average, the class, the distance to the next line, and the score you would need on your next classifier to cross it. Then it does the harder half: the score you would need on your next classifier to get there.
The window it uses is the one USPSA’s published algorithm states in prose — the best six of your most recent eight, averaging everything on record until six exist. That same document takes a different route in its own flowchart for a shooter who is not yet classified, and the two do not agree. Where the difference would change your class letter, this page shows you both numbers rather than picking one for you. (New to the math? How classification works.)
Your calculator entries are remembered only in your own browser — no number you enter into these calculators is ever sent anywhere. A “Copy a link” button puts your entered numbers in the link itself, which is what makes a result shareable. 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.
What's my USPSA class?
Enter your recent classifier percentages, most recent first. You need 4 valid scores from 4 different classifier stages to be classified at all, and your average is then the best 6 of your most recent 8 — all of them, until six are on record. That is the window this tool uses, and it is what the prose of USPSA's published algorithm says — though the same document takes a different route in its own flowchart for a shooter who is not yet classified, which is what the flag below is for. This tool asks for 4 rather than 6 because 4 is the point at which USPSA will classify you — asking for more would turn away the shooter who has just got there. (New to the math? How classification works.)
Enter at least 4 classifier percentages.
USPSA's published algorithm states the window before a first classification two different ways, and the two do not agree.
“If more than four scores are in the database when the averages are calculated, the best six of the most recent eight valid scores will be used. Any scores in excess of the most recent eight valid scores are not used for the initial classification.”
“Use initial 4 or best 4 of most recent 6”
The first is the prose of USPSA's published classification algorithm. The second is the step that document's own flowchart takes for a shooter who is not yet classified, and its table of score flags describes the same window as six scores. USPSA has not resolved the difference.
The number above reads it the first way: . Read the second way, you are at . Your official classification is the one USPSA posts.
Your number, the way your log shows it — current after every classifier you add.

What do I need on my next classifier?
Enter your recent classifier percentages, most recent first. It adds your next one and recomputes the best 6 of your most recent 8, then shows the score you'd need to climb a class. Four is enough to start, for the same reason as above — that is where USPSA classifies you.
Enter at least 4 recent classifiers above, most recent first.
Your standing today, the way your log shows it. Log the next one and this updates itself.
FirearmLog answers this inside your log — which scores count, which drops next, and the score that moves you up. See yours in the web app →
The USPSA class scale
Your classification percentage is placed on this scale. The calculator above uses these same numbers. The table lists each class with the percentage band it covers; it scrolls sideways on a narrow screen to reach the classification-percentage column.
| Class | Classification percentage |
|---|---|
| D | 2.00–39.99 |
| C | 40.00–59.99 |
| B | 60.00–74.99 |
| A | 75.00–84.99 |
| Master | 85.00–94.99 |
| Grand Master | 95.00–110.00 |
USPSA’s published table starts at D and says nothing below 2.00%. The April 2025 system update raised the score ceiling to 110% of the recommended high hit factor, so a percentage above 100 is possible.

Checked against USPSA’s published classification algorithm on 31 July 2026. That document carries no edition number, and the classification math is not in the numbered rulebook — which is why this page quotes the algorithm rather than a rule.
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.
Thanks — that's with me, and I'll take a look.
