ADR, Headshot % & K/R Calculator (FPS)

Understanding the ADR, headshot % and K/R calculator — concept and principle

In round-based tactical shooters such as Counter-Strike 2 and Valorant, a match can last 13 rounds or 30, so total kills and damage are hard to compare. This calculator converts your totals into three per-round or ratio statistics that scouts, analysts and stat sites use: average damage per round (ADR), kills per round (K/R or KPR) and headshot percentage.

ADR is compared with one player’s 100 HP; headshot % counts the orange-centred kills.

How it is calculated

ADR = total damage ÷ rounds played.
Kills per round = kills ÷ rounds played.
Headshot % = headshot kills ÷ kills × 100.

Rounds means every round of the match you took part in, won or lost. Damage is damage dealt to enemies; most trackers count only the damage up to the opponent's remaining health and exclude damage to teammates.

The principle

Dividing by rounds turns a match total into an average contribution per round, the natural unit of play in these games. ADR rewards damage that does not always end in a kill, such as softening an opponent for a teammate, which kills alone miss. KPR measures how often you finish fights. Because a player in Counter-Strike has 100 health, an ADR of 100 means you dealt one full player's worth of damage every round on average. Headshot % reflects aim placement: head hits multiply damage, so a high share usually means faster kills.

Worked example

Inputs: 2,100 damage, 24 rounds, 22 kills, 11 headshot kills.
ADR = 2,100 ÷ 24 = 87.5.
Kills per round = 22 ÷ 24 = 0.92 (0.9166666667).
Headshot % = 11 ÷ 22 × 100 = 50%.

Each point is the calculator re-run with only “Rounds” changed; the gold point is the default example. Change the inputs above and this chart follows your numbers.

Rounds	ADR
6	350
12	175
18	116.6666667
24	87.5
30	70
36	58.33333333
48	43.75

How to read the result

As a rough guide for Counter-Strike, an ADR around 70 to 80 is typical, 85 or more is strong, and 100 or more over many matches is exceptional. A KPR near 0.7 is about average at a competitive level, and anything above 0.85 is a high-impact game. Headshot share varies with role and weapon: riflers often land between 40% and 60%, while AWP players show lower values because body shots already kill. Read the three together; a high headshot % with a low ADR may mean you take few duels.

Common mistakes

Dividing by rounds won instead of all rounds played.
Comparing Valorant and Counter-Strike values directly; health, armor and economy differ.
Mixing definitions: Valorant trackers usually report headshot share of all hits, not of kills.
Judging a single map; ADR swings a lot over 20 rounds.

Keep in mind: These averages describe output, not decision-making. They ignore trades, utility, clutches and role, and small samples are noisy, so judge trends across many matches.

Frequently asked questions

What is a good ADR in CS2?

Over a meaningful sample, 80 or more is good in most competitive settings and 100 or more is elite.

Is K/R the same as K/D?

No. K/D divides kills by deaths; K/R divides kills by rounds and is not affected by how often you die.

Why can my ADR exceed 100?

Multi-kills and damage spread across several opponents in one round add up, so the per-round average can pass one player's health.
