How do I incrementally increase a value based on another list of incremental values?

[acousticsman]

I am tying to create a price list, I have the following data.

QTY	Cost	Design	Sell
250	£17.08	£10.00	£32.71
500	£20.39	£10.50	£37.61
1000	£24.40	£11.03	£43.48
2500	£33.67	£12.16	£56.94
5000	£50.69	£12.76	£80.18

QTY - The quantity of prints
Cost - The cost of the prints
Design - Cost of design
Sell -

(1.33 is the markup on the print)


Now the design price increases incrementally, with the base quantity being the base design price and each increment coumpunding by (in this example) 5%.

Would I be able to do this increment automatically, using a formula, with the quantity column as the reference?

So something like, if QTY is ranked the lowest value, then design price is the base, and with each incremental quantity, increase design price by 5%.

To best describe or illustrate your problem you would be better off attaching a dummy workbook. The workbook should contain the same structure and some dummy data of the same type as the type you have in your real workbook - so, if a cell contains numbers & letters in this format abc-123 then that should be reflected in the dummy workbook.

To attach a file to your post,
click advanced (next to quick post),
scroll down until you see "manage file",
click that and select "add files" (top right corner).
click "select files" find your file, click "open" click "upload" click 'done" bottom right. click "submit reply"

Once the upload is completed the file name will appear below the input boxes in this window.
You can then close the window to return to the new post screen.

I have figured it out, by creating a new column with the rank function it, then using the fv function.
