What is the ACFT Sprint-Drag-Carry Score Calculator?
This tool applies to the US Army Combat Fitness Test (ACFT). The Sprint-Drag-Carry (SDC) is a five-shuttle event run on a 25-meter lane: a sprint, a sled drag, a lateral, a kettlebell carry, and a final sprint. This calculator converts your recorded SDC time into the standard 0–100 ACFT point score, where a faster time earns more points. Scoring assumptions follow the published ACFT scoring scale: 100 points at 1:33 or faster, 60 points (the minimum passing standard) at 3:00, and 0 points at 4:18 or slower.
How to use it
Enter your total SDC time in minutes and seconds, then read your score. The calculator linearly interpolates between the anchor points and rounds to the nearest whole point, clamping the result between 0 and 100. It also tells you whether you cleared the 60-point passing threshold.
The formula explained
Total time in seconds is \(t = \text{minutes} \times 60 + \text{seconds}\). Two linear segments are used. Between 1:33 (93 s) and 3:00 (180 s) the score falls 40 points over 87 seconds, so $$\text{Score} = 100 - (t - 93) \times \frac{40}{87}$$ Between 3:00 (180 s) and 4:18 (258 s) the score falls 60 points over 78 seconds, so $$\text{Score} = 60 - (t - 180) \times \frac{60}{78}$$ Outside those bounds the score is clamped to 100 (very fast) or 0 (very slow).
Worked example
Suppose you run the SDC in 2:00, i.e. \(t = 120\) seconds. That lands in the upper segment: $$\text{Score} = 100 - (120 - 93) \times \frac{40}{87} = 100 - 27 \times 0.4598 \approx 100 - 12.41 = 87.59$$ which rounds to 88 points — comfortably passing.
Key Terms Explained
- ACFT (Army Combat Fitness Test)
- The U.S. Army's physical fitness assessment, consisting of six scored events designed to measure muscular strength, endurance, power, and aerobic capacity. Each event is scored 0–100 for a maximum total of 600 points.
- Sprint-Drag-Carry (SDC)
- A timed ACFT event in which the soldier completes five consecutive 50-meter shuttles (sprint, sled drag, lateral, carry, and a final sprint) on a 25-meter lane. The total elapsed time is converted into a 0–100 point score.
- Shuttle
- A down-and-back segment of the lane. Each shuttle covers 50 meters total — 25 meters down the lane and 25 meters back — and the SDC consists of five shuttles for 250 meters of movement.
- Sled Drag
- The shuttle in which the soldier grasps the straps of a weighted sled and drags it backward down and back along the lane.
- Lateral
- The shuttle performed with a side-to-side (lateral) shuffle, facing the same direction throughout while moving sideways down the lane and back.
- Kettlebell Carry
- The shuttle in which the soldier carries two kettlebells, one in each hand, down the lane and back.
- 25-Meter Lane
- The marked course used for the SDC. Each leg of a shuttle is 25 meters, so the soldier turns at the 25-meter mark and returns to complete one 50-meter shuttle.
- Point Score
- The 0–100 value assigned to an event based on the soldier's measured performance (time for the SDC), determined by the Army's published scoring scale.
- Passing Standard
- The minimum score required to pass an event — 60 points on each ACFT event. For the SDC this corresponds to a completion time of 3:00 (180 seconds).
FAQ
What time do I need to pass? You must finish in 3:00 (180 seconds) or faster to earn the minimum 60 points.
What time gives a maximum score? 1:33 (93 seconds) or faster scores the full 100 points.
Is this the official score? It mirrors the published ACFT SDC scoring scale, but always confirm against your unit's current official scorecard, as standards can be updated.
