Javascript per second calculation

I am currently wracking my brain to work out what should probably be a relatively simple per second calculation. I have a loading bar increase and at the end of that, it adds 1 to the total. The loading bar consists of:

wId = setInterval(worker_identify_call, wIdSpeed);

and

function worker_identify_call(){
    worker_identify_amount++;
    wElem.style.width = worker_identify_amount + '%';
}

wIdSpeed = 250.

I am trying to calculate how long, in seconds, it will take to reach the top of the loading bar (100%).

I currently have ((1000/wIdSpeed).toFixed(2)) but that just calculates how long a cycle of setInterval takes.

CodePen with example here.

Any help is appreciated!

If you want to recalculate after every cycle you have to move workerString(); to inside the function that loops.

As for the math, you need to get the remaining (100 - worker_identify_amount) and check how many things it's adding per second and figure out the result from that.

I'm in idiot. For anyone that wants to find this in the future, it would be:

(((wIdSpeed/1000)*100).toFixed(2));

Where wIdSpeed is the speed of your interval.
