Boxing Round Scoring Calculator
10-point must scoring for boxing rounds.
About this calculator
This calculator scores a single boxing round under the 10-point must system by turning raw CompuBox-style stats into a weighted composite: clean punching landed carries 45% of the round score, power punches landed 20%, effective aggression 18%, and ring generalship 17%. Punches landed and power shots are each normalized against whichever fighter did more of that thing this round, so the comparison is always relative, not absolute. If the two fighters' weighted scores land within 0.3 of each other, the round is called even at 10-10 — otherwise the leader gets 10 and the other fighter gets 9, or 8 if the gap is 3.0 points or more, mirroring how judges reserve 8-round scores for rounds that were thoroughly dominated or ended in a knockdown.
Each knockdown a fighter suffers subtracts a full point from their round score, independent of the composite math, matching the mandatory automatic deduction real judges apply. The projected totals simply multiply this round's score by the scheduled number of rounds, which is a simplification worth knowing: it assumes the same round pattern repeats from bell to bell, so it won't capture a fighter who fades in later rounds or rallies down the stretch. Use it to sanity-check a scorecard for one representative round or to explore how shifts in accuracy, power, aggression, or a knockdown would swing a fight's outcome — not as a literal round-by-round prediction.

Frequently Asked Questions
Why can a fighter with more punches landed still score only a 9-9 or lose the round?
Punches landed is only 45% of the weighted score — power punches landed, effective aggression, and ring generalship make up the rest. A fighter who lands more total punches but gets out-landed on power shots, out-worked on aggression, and out-positioned on ring control can still lose the composite score, and the round gets scored on that composite, not on the punch-landed count alone.
How does a knockdown actually affect the round score in this calculator?
A knockdown subtracts a full point from the knocked-down fighter's round score after the composite scoring is already decided — it's applied on top, not folded into the weighted formula. So even a fighter who's winning the exchange-by-exchange numbers can see their round score drop from 10 to 9 (or the other fighter's from 9 to 8) purely from being dropped once.
Why does the calculator treat any score gap under 0.3 as an even round?
The weighted composite score is a continuous number, but boxing only recognizes 10-10, 10-9, and 10-8 rounds — there's no way to award a 'slightly ahead' round. A 0.3-point threshold acknowledges that two fighters whose composite scores are nearly identical didn't have a clearly separable round, the same judgment call real judges make when a round is genuinely close.
Does the projected total score account for a fighter getting tired or finishing strong?
No — the projected total just multiplies this single round's score by the number of scheduled rounds, assuming the exact same performance repeats every round. It's meant as a quick 'if this round were typical' projection, not a fight simulation, so it won't reflect a fighter who fades after round 6 or one who finds their rhythm in the championship rounds.
