How it works

The calculator divides total users by ramp-up duration to estimate users-per-minute and users-per-second, helping configure JMeter, k6 and Gatling scenarios.

Formula

users_per_minute = total_users / ramp_minutes
users_per_second = users_per_minute / 60

Use this as a baseline and adjust for environment constraints or warm-up strategy.

Example

For 1000 users over 10 minutes, ramp-up is 100 users/minute (about 1.67 users/second).

FAQ

Should I ramp all users at once?

Usually no. Gradual ramp-up reveals bottlenecks and avoids unrealistic spikes.

Can I use decimal ramp values?

Yes, the output supports fractional users-per-second planning.

Is this tool tied to one framework?

No. It works for any load framework with ramp settings.
