Hi Guys
I am running into a problem using the NPV calculation and a subsequent amortization calculation.
Please see attached:
I used the NPV formula to calculate the NPV of a 12 month variable cash flows. This is equal to the opening balance of a liability. 213,473)
When i develop an amortization schedule including interest cost uisng the cash flow as the payment schedule, the end balance is not zero.
I attached the results as well as the formula used..
I am not sure where i made the mistake?
Thank you in advance
Hi @Roelofg ,
I think the NPV of this would be 206,929.
Please check the excel attached, and could I see the whole formula of your NPV formula.
I am on the way to studying finance, and it would be useful for me.
I hope it helps.
213,473...
I will investigate..
Hi @Roelofg
I finally got to understand the Anaplan NPV function in the monthly calendar.
Comparison with Excel NPV function:
1) Month 1 cashflow
(E) discounted
(A) not discounted
2) Discount Rate
(E) ((1 + Annual Rate) / 12) ^ (Number of Months)
(A) (1 + Annual Rate) ^ (Number of Month / 12)
So in your situation, the NPV function of Excel and Anaplan differs.
(E) 206,929 (A) 207,926
See attached Blueprint, too.
Despite of the Anapedia NPV function page, you should set the NPV discount rate be the annual rate.
I cannot fully understand this document.

This topic tought me how it works!
Thank you.

FYI
Difference 2 is less necessary because we can use NPV((1+r)^(1/12), Cash flow) in Excel as @tingtingxia did.
In Excel, we can choose from two monthly discount rates.
In the Anaplan, an exponential discount rate only, but it would be correcter Math.
Thank you for this....
I used the suggested above and sorted out the problem.
The issue around NPV is also to account for when the payments is made in the beginning of the (monthly) period or at the end of the (monthly) period. To be quite honest i do not trust the NPV formula on this stage.
It is easy to check it and that is to build an amortization schedule on the input and results of the NPV formula. The theory is that the balance must be 0 at the end of the period. But is does not.
Thanks for the input.
Hi
Just some observation/question from my end for your reference:
1. Your 1st line item is "Annual Interest Rate" but your module is in monthly bucket. If your 5% is really Annual, then your monthly discount rate would be 12 square root of (1+5%) then minus 1
2. Your payments in NPV line item is not discounted by the discount rate (your first line item)
The rest I am not able to see the full formula, it would be great if you can share an export of your module in Excel.

Hi
I have looked into your Excel and modified the monthly discount rate calculation to the one I mentioned previously. Now the End liability at the last month will be zero.

Interest Calculation:
