Rounding time with a Vlookup or a better way...

I have myself a bit turned around with this time project. In a nutshell, I have built a sheet to track time. Once it is tracked it will come to this totals page.
When we have the total amount of time the employee will get paid for....It is based on 15 minute increments. If it is below 7 minutes, it goes back to 0.
If it is  8min-22 minutes it is rounded to 15min. 23-37 is 30min. 38-52 is 45min. Anything greater than 52 is added to the top of the hour. So, 4 hours and 55 minutes will
get paid for 5 hours.

I took this idea and formed a vlookup formula. But, I must admit I am totally lost. Any help with the formula or a better way to achieve this is greatly appreciated.

At first glance, your Vlookup in cell e16 looks fine, and it looks like you're on the right track for what you want to do, but you copied it to the right without locking the address down.  The correct way to formulate the lookup is:

=VLOOKUP(G15,$J$1:$K$6,2,TRUE)

The dollar signs keep the range you're looking at from changing.  Just copying it to the right fixes the problem.

Hello,

your formula and idea are fundamentally correct, but the Vlookup refers to the wrong range. Instead of

=VLOOKUP(G15,L1:M6,2,TRUE)

use

=VLOOKUP(G15,J1:K5,2,TRUE)

cheers, teylyn

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

And I updated your table, you were missing the 38-52 traunche.

You might be correct with buckets, but can't find something that helps sort out my issue.

@bvanscoy678, - execuse me - it appears you accepted an answer that was subordinate to mine.  not only did I repair your VLOOKUP, but the VLOOKUP range - and did the prior before Teylyn did.

Please explain.

My apologizes. It was a simple error of not looking close enough. I thought it was the same person.
Dave, Sorry...honest mistake. I appreciate both posters help.

Thanks

I figured as much and have done the same thing.  

No worries.
