Hi Experts, Id like a solution to solve the following error i have in my formula

[qty*1.1rnd0.3/4.2rnd1] /4.2

What Im wanting to do here is, whatever qty i add, i need the formula to add 10%, then round up to the next increment of 0.30, then i want it to divide by 4.20 and round up to the next full 4.20, the result to have 4.2 shown

If I enter the qty as 1.80 and have the formula work correctly, it should give me the following result 1/ 4.20
Here are the calculation steps that should be taken
1.98 roundup into increments of 0.3 = 2.10
2.10 / 4.20 = 0.50
0.50 roundup into increments of 4.20 = 4.20
final result = 1/ 4.20

If A1 contains the qty then enter this formula in another cell and it will give you the desired result (I hope)


I'm assuming that you need to prefix the numeric result with the text "1/"
="1/" & TEXT(ROUNDUP((ROUNDUP(A1*1.1/0.3,0)*0.3)/4.2,0)*4.2,"#,##0.00")

Before adding the prefix, it's the same as Saqibh's approach, except that I rounded up to the nearest 0.30 rather than 0.33333333

Hi Brad, I thought mine rounds to 0.30, how do you say it rounds to 0.33333?

This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.


You are correct. I was wrong about how the ROUNDUP function is working.

Rob Henson

You could use the MROUND function or the CEILING function.

MROUND rounds to the nearest multiple specified

CEILING rounds up to the next multiple specified.

With quantity in A2, use formula:

=TEXT("1/ "&CEILING(CEILING(A2*1.1,0.3)/4.2,4.2),"0.00")
