So, assuming you have 150k of 3 loan disbursements all at same interest rate you should pay off the largest (oldest) first bc interest rate * largest number results in largest interest accrual amount.
You don't seem to understand how interest works. Just look at the rate, the principal amount is irrelevant.[/quote]
Yup
For example:
Loan 1: $65k at 5% (annual interest is $3.25k)
Loan 2: $55k at 5% (annual interest is $2.75k)
Loan 3: $45k at 5% (annual interest is $2.25k)
Ability to pay $50k
No matter how the $50k gets distributed the annual interest remains the same:
Loan 1: $15k - interest is $0.75k
Loan 2: $55k - interest is $2.75k
Loan 3: $45k - interest is $2.25k
Total interest = $5.75k
Loan 1: $65k - interest is $3.25k
Loan 2: $50k - interest is $2.50k
Total interest = $5.75k
However, I also think that if you have different loans
all at the same rate, and it's possible to pay one off in its entirety, this is highly advisable.
For example (different numbers)
Monthly payment on loan 1 = $150
Monthly payment on loan 2 = $100
Monthly payment on loan 3 = $50
Total time remaining on all loans is 25 months.
If payment is applied equally, total time remaining becomes 20 months, and will cost a total of $300 per month
If loan 3 is paid off in its entirety, you've got two options:
Monthly payment on loan 1 = $150 - paid off in 25 months
Monthly payment on loan 2 = $100 - paid off in 25 months
(total monthly payment of $250)
OR
Monthly payment on loan 1 = $180 - paid off in 20 months
Monthly payment on loan 2 = $120 - paid off in 20 months
(total monthly payment of $300)
TCR would be to select option 2 - keep paying the same amount every month and finish early. However, doing it this way gives the added flexibility that if you ever need some extra cash, you can reduce payments for one or both of the loans down to the original amounts, and pocket the difference - to be used for emergencies only (make sure you have enough self-control)
