-------------------------------------
I spend some time on verifying this issue and it seems that corret calculations
are only in e-release. So, in G and F releases the interests are calculated
wrong.
To reproduce this bug follow these steps (in G-Release):
1. Set the following properties in custom properties file:
AccountingRules.DigitsAfterDecimal=1
AccountingRules.InitialRoundingMode=HALF_UP
AccountingRules.FinalRoundingMode=CEILING
AccountingRules.CurrencyRoundingMode=HALF_UP
AccountingRules.InitialRoundOffMultiple=1
AccountingRules.FinalRoundOffMultiple=1
2. Login to Mifos.
3. Go to 'Client&Accounts' tab and click on 'Create Loan Account' link.
4. Select any Client with weekly meetings and any Loan product with interest
rate type: Declining Balance.
5. On 'Enter Loan account information' page enter the following data:
- Amount: 1000
- Interest rate: 20
- Number of installments: 5
6. Click on 'Continue' button.
7. Notice that on 'Review installments' page, the last Principal=202.7, last
Interest=0.7 and last Total=203.5
8. Click on 'Preview' button.
9. Notice that on 'Preview Loan account information' page, the last
Principal=202.7, last Interest=0.7 and last Total=203.4
Expected result:
On 'Review installments' page and 'Preview Loan account information' page
nubers should be the same and on both pages these numbers are incorrect.
According to the loan-repayment-master.xls file and my calculations the correct
numbers for the last payment should be:
- Principal=202.7
- Interest=1.3
- Total=204.0
> In Release 2.2, interest calculation for variable installment loans is
> different than in Release 2.1.x
