0-60 Calculator
Your timed run
Example: 30 mph in 2.0 s → 0-60 in 4.0 s, about 176 ft.
Behind the numbers
How a 0-60 time is calculated
This calculator assumes constant acceleration — the car gains speed at the same rate from a standstill all the way to 60 mph. That is a simplification: real cars accelerate harder at low speed and a little slower as speed rises, so the result is a good estimate, not a track-tested time. First it finds the acceleration rate by dividing the speed you reached by the time it took. Then it divides 60 mph by that rate to get the 0-60 time. It also works out the distance covered, because distance grows with the square of time at constant acceleration.
Acceleration = speed reached ÷ time. For the example: 30 mph ÷ 2.0 s = 15 mph per second. 0-60 time = 60 mph ÷ acceleration = 60 ÷ 15 = 4.0 seconds. Distance uses the same rate in feet: 15 mph per second is 22 ft/s², so distance = ½ × 22 × (4.0)² = 176 feet.
Examples
Example runs
| Speed reached | Time | Acceleration | 0-60 mph time |
|---|---|---|---|
| 20 mph | 1.5 s | 13.33 mph/s | 4.50 s |
| 30 mph | 2.0 s | 15.00 mph/s | 4.00 s |
| 40 mph | 2.5 s | 16.00 mph/s | 3.75 s |
| 45 mph | 3.0 s | 15.00 mph/s | 4.00 s |
| 60 mph | 5.0 s | 12.00 mph/s | 5.00 s |
Tips for a better measurement
Use a GPS speed app or a drag-timing app instead of your speedometer, which can read a little high.
Test on a flat, straight, dry road with no traffic, and repeat the run twice to check the numbers agree.
Start from a full stop with the timer running — a rolling start makes the time look faster than it is.
Note the weather and fuel load: a full tank, passengers, or a hot day all slow the car slightly.

Frequently asked questions
Is this 0-60 time exact?
No. It is an estimate based on constant acceleration. Magazine and manufacturer times come from real instrumented runs, and they usually differ a little from this estimate because real acceleration is not perfectly constant.
What if I timed a full 0-60 run directly?
Then just enter 60 mph and your time — the calculator returns the same time back. It is most useful when you only timed a shorter run, such as 0-30 mph.
What is a good 0-60 time?
Most family cars do 0-60 mph in about 7 to 9 seconds. A quick sports sedan is around 4 to 5 seconds, and high-performance electric cars can do it in under 3 seconds.
Why does the calculator show distance too?
Distance tells you how much road a launch needs. At a 4.0-second 0-60 time the car covers about 176 feet — more than half a football field — before it reaches 60 mph.
