Recovery Curve VBA Code help to reduce repetitive Parts

[dariushou]

HI Everyone,

I have some vba code that I’ve been using for years that I use to project the recoveries of an asset over some period of time according to a vector. So if I have cash outlay in period 1, I have a curve that recovers that cash amount over some period time (let’s say 24 months). In period 1, I would multiply the first value in the 24 month vector by the initial cash amount so that 100% is recovered in month 24. If there is another cash outlay in period 2 then that cash would also be recovered according to the same curve. So in period 2, you multiply the Cash Amount from Period 1 by the 2^nd value in the vector…then the Cash Amount from Period 2 would be multiplied by the 1^st value in the vector and so forth.

This code works perfect for that. The issue is the code can become very cumbersome. I’m hoping someone can help me reduce the repetitive parts of the code…I’m about to have 100s of different curves and cash amounts so typing in 100 different arrays is going to be painful.

I can't seem to be able to attach the spreadsheet. In its current form the spreadsheet just has 5 recovery curves and asset amounts. All of the recovery curves are next to each other. The cash amounts are in columns next to those and the results are printed in the columns to the right of the cash amounts. So 1^st 5 columns are the recovery curves, next 5 columns represent different types of cash flows that occur in each period. (the curves start in column B – I reserve the first column for the Month so in row 7, column A, is “1”, in the next row in column A is the number “2”…so 1,2,3,4…

I couldn't attached the spreadsheet, but here is the data in excel in table format. the data starts on row 7 so Month 1 is row 7.

Any help on this. My big issue is the below code. Just can't seem to figure out the right way to only have one cfArray variable instead of 5. I would think this could be done in a for loop, but i've failed miserable at trying to figure it out.

Thanks,
Darius

cfArray1(X, 0) = cfArray1(X, 0) + myArray(i, C1 + 0) * myArray(p, C2 + 0)
cfArray2(X, 0) = cfArray2(X, 0) + myArray(i, C1 + 1) * myArray(p, C2 + 1)
cfArray3(X, 0) = cfArray3(X, 0) + myArray(i, C1 + 2) * myArray(p, C2 + 2)
cfArray4(X, 0) = cfArray4(X, 0) + myArray(i, C1 + 3) * myArray(p, C2 + 3)
cfArray5(X, 0) = cfArray5(X, 0) + myArray(i, C1 + 4) * myArray(p, C2 + 4)
