Thanks so much Binny, tried the same formula for the another period, not 
matching.

22-Dec-20
14-Mar-21
82
360
10%
84,000.28
1913.339666
1,900.01
I used your logic (2+(24/30)), (2+24/31), all gives different results, none 
matching. Am I taking the right number?

On a broader note, is it right to take 31 day for calculation while I 
specifically selected the 30/360 method for calculation? Is it a flaw?

Hi Saif,

I have not fully validated your excel sheet. However, here is my understanding:

Fineract treats a full month as 20th to the next 20th date. But when a partial 
month is involved, Fineact does an exact-days-based calculation.

In your example 20th Dec 2020 to 20th Jan 2020 is treated as one full month
The period from 20th Jan to 14th Feb has 25 days and the full month (20th Jan 
to 20th Feb) would have had 31 days - so it is treated as 25/31th portion of a 
month.

84,000.28 * 10% / 12 * ( 1 + 25 / 31 ) = 1,264.52

Hope this will be of some help.

Regards
Binny

I am new to Fineract and presently trying to learn the platform. I created a 
loan product with the following terms


Principal - 100000; Interest - 10%/year; 12 months duration; declining balance; 
30/360 method

How does the interest calculation part work here? I tried doing a sanity and 
found a difference of 4/- for a mount of 100000 issued over for a period of 12 
months with 10% interest/year


Step 1: Disbursed Loan on 20-Oct
Step 2: Repayment of 2 EMI (Nov, Dec)
Step 3: Reschedule Loan from 20 Jan 2021 to 14 Feb 2021
Step 4: View Repayment schedule
Step 5: See the interest calculated for 14 Feb 2021 as 1,264.520

While validating manually (Interest = P-Pp*10%*54/360), as the duration comes 
as 54 days and upon calculation it comes as 1260/- only, whereas fineract gives 
1264.50/-

I am not sure from where the difference 4 has come during the calculation.
