    I'm not sure but I think what the OP is getting at is that the partial payments need to be taken into account such that the 10% is applied to the remaining balance at that time. So if the original loan is 1000 and 10% interest so principle & Interest is 1100 that has to be paid by due date but if only 500 was paid then 600 is outstanding balance and would get 10% penalty so new loan balance would be 660 the month after the due date and if they paid 260 then the next month would have another 10% penalty but only on the remaining 400 so the new balance would be 440.
    Maybe Mbarak630 could confirm or correct this
    If this is the case I think we could use LAMBDA function with REDUCE to do this

You are correct, i was just trying to see if a customer has two loans, what was the effect and i saw the issues arising, and so to avoid it then only one loan for a customer and must be cleared before another is taken.

 

Also, its better if I use the Loan ID, and the penalties were necessary because if loan wasnt paid by due date, then the penalties apply.

 

I will replace customer name with Loan ID

If I remember correctly the problem is that this formula doesn't track which loan a given payment is being applied to. Technically the 2 loans could overlap as long as the first is paid off before the DUE date of the next. An additional conditional on the penalty accrual function could be added to check if the NET total payment has exceeded all prior loan commitments (i.e. prior loans paid off) and not apply payments until that happens.

    Mbarak630  OK i re-worked the formula to track the amount paid toward this loan and hence only apply discount on the penalty based on +pays against this loan and cap penalties if pay>base+penalties.  Basically this new version should allow for multiple loans 🙂

    try it out ...

    yes, payments made were and the allocation was given priority to the earlier loans.

     

    I think best is to avoid multiple loans running for one customer, but stick one loan per customer and until it is fully paid inclussive of all penalties and there is no outstanding amount, then a new loan can be
