Mortgage payoff logistics

Actually, no you aren't. You pay interest based on the remaining principal balance. If you pay a payment the first day of the month, your balance is decreased by the amount applied to principal. If you pay another payment the next day, interest is calculated on that new balance. It doesn't stay the same as it was on the first of the month. Interest is always recalculated on the remaining balance each time a payment is made.

Actually, I am correct. The previous months interest is added to the current balance at the beginning of the month.If you make an extra principle payment during the month they do not make any additional interest calculations.The only time they charge a pro-rated interest payment, is when you pay off your mortgage, and when they do that they use the current balance, not the balance at the beginning of that month. I will give you some examples to better explain how this works.For the sake of simplicity in my examples I will use $100,000 beginning balance, 6% annual interest rate, and a $1000 regular monthly payment.

Example 1: Calculating interest when an extra interest payment is made that month.

Month 1
beginning balance: $100,000
Day 1: interest charge for last month: $ 500(6% / 12 = .5%)
Day 1: This month's payment: $ 1,000
Day 1: Balance at end of day: $ 99,500
Day 30: Extra payment: $ 10,000
Ending balance month 1: $ 89,500

Month 2
beginning balance: $89,500
Day1: interest charge for last month: $ 447.50 (6% / 12 = .5%)
Day1: This months payment: $ 1,000
Day1: balance at end of day: $ 88,947.50

As you can see from this example, it does not matter what day that extra principle payment is made. When they calculate interest you essentially get credit like that principle payment was there the whole month.

You can similarly save money by understanding the way they calculate interest when it comes time to pay off the whole mortgage. When they do the pro-rating of interest, they look at the current balance, and the number of days left in the month.In other words you can save money by making a big principle payment, before the final payoff.Here are two more examples to illustrate what I am talking about.For simplicity I will not include any deed recording fees, or other similar fees, as those would be the same in either case.

Example 2: Paying it off all at once on the 15th

Day 1 Beginning balance: $ 100,000
Day 1: interest charge for last month: $ 500
Day 1: This months payment: $ 1,000
Day 1: Balance at end of day: $ 99,500
Day 15: Payoff interest calculated: $ 248.75(15 days at 6% annual = .25%)
Day 15: Final payoff amount: $ 99,748.75
Day 15: End of day loan balance: $ 0

Total payments made this month: $ 100,748.75

Example 3: Making an extra payment before the final payoff
Day 1 Beginning balance: $100,000
Day 1: interest charge for last month: $500
Day 1: This months payment: $1,000
Day 1: Balance at end of day: $99,500
Day 10: Extra principle payment: $ 99,400
Day 10: Balance at end of day: $ 100
Day 15: Payoff interested calculated: $00.25 (15 days at 6% annual = .25%)
Day 15: Final payoff amount: $ 100.25
Day 15: End of day loan balance: $ 0 :dance:

Total payments made this month $ 100,500.25

Now I understand why people might be skeptical. When the mortgage expert I talked to explained this to me, I was very surprised, and asked her multiple times just to make sure I understood it correctly.When I paid off my mortgage I used this information to minimize my interest. I calculated all the interest just as she said to, and it matched the bank's interest down to the penny.So I got confirmation that this is in fact how they calculate things.

This is a great tip. Thanks! Will give it a try when I pay off my mortgage.
 
Maybe it's just your terminology, but some of your explanations are not exactly correct. First of all, interest is never added to the principal balance (not on an ordinary amortizing loan. Negative am loans are different). We will assume this discussion only involves an ordinary amortizing loan (not negative am, not daily interest). It is part of a payoff quote, yes, but it is not added to the principal balance.

When you have a payment due for Oct 1, and you pay that payment in Oct (doesn't matter what day in Oct) then you pay the interest that had already accrued for Sept and the principal due for Oct. No October interest is paid in the payment. When making a payment, you are always paying the previous month's interest, not the current month’s interest. When you pay Nov payment, you are paying the interest that accrued in Oct, and so on.

If you make an additional payment to principal at any time during October after the payment due for October is made, when your November payment comes due interest is calculate on the new principal amount after the extra payment to principal is made. When you make your Nov payment, you pay interest for October but based on the lower UPB, not the UPB as of the first of October.

When it comes time for a payoff calculation, and if you have not yet made a payment for the month, then you will be charged interest for the previous month (remember, interest is always paid in arrears) and the number of days in the current month up to, but not including the day of payoff. All interest is calculated on the principal balance outstanding as of the date of payoff. If you have already paid the current month's payment, you will only be charged the interest due for the days in the current month up to but not including the date of payoff (since your current month’s payment paid the accrued interest for the previous month). Again, the payoff is calculated on the UPB as of the date of payoff.

You comment that if you make a large lump sum payment to principal in the previous month prior to payoff, the interest calculation at the time of payoff will be based on that lower UPB is correct. Or, you can also make your current payment on day 1, then a large principal payment on that same day or another day. Then after both your payment and principal payment have been posted, you request a payoff and it will be calculated on the new, lower UPB after both the payment and principal payment have posted.

So, maybe this is what you are saying, but just using different words.

After working 34 years in the industry, I think I have a pretty good understanding how this works.

This distinction of whether the interest is added to the current balance or held on some other line item in some accounting journal is not relevant to the substance of this discussion.

No October interest is paid in the payment. When making a payment, you are always paying the previous month's interest, not the current month’s interest. When you pay Nov payment, you are paying the interest that accrued in Oct, and so on.

Not sure why you felt the need to say this, In my examples I said that it was last month's interest they were charging.


If you make an additional payment to principal at any time during October after the payment due for October is made, when your November payment comes due interest is calculate on the new principal amount after the extra payment to principal is made. When you make your Nov payment, you pay interest for October but based on the lower UPB, not the UPB as of the first of October.

umm... The UPB (Unpaid Principle Balance) after the last principle payment is made in the previous month, will always be equal to the beginning balance of the Next month. In other words the ending balance of the 1st month is the beginning balance of the 2nd month.:facepalm:

When it comes time for a payoff calculation, and if you have not yet made a payment for the month, then you will be charged interest for the previous month (remember, interest is always paid in arrears) and the number of days in the current month up to, but not including the day of payoff. All interest is calculated on the principal balance outstanding as of the date of payoff. If you have already paid the current month's payment, you will only be charged the interest due for the days in the current month up to but not including the date of payoff (since your current month’s payment paid the accrued interest for the previous month). Again, the payoff is calculated on the UPB as of the date of payoff.

I really think you are trying to make this more complicated than it really is.

You comment that if you make a large lump sum payment to principal in the previous month prior to payoff, the interest calculation at the time of payoff will be based on that lower UPB is correct. Or, you can also make your current payment on day 1, then a large principal payment on that same day or another day. Then after both your payment and principal payment have been posted, you request a payoff and it will be calculated on the new, lower UPB after both the payment and principal payment have posted.

In my payoff example I did not talk about making a large principle payment the month before the actual payoff. However, it seems we agree that if you make a principle payment before your payoff date, the amount of that payment will not be figured in to the partial month interest you pay as part of the payoff. This is the main point I wanted to get across to forum members, because this is the point that is going to put money in their pocket.

So, maybe this is what you are saying, but just using different words.

I think you know the jargon, and can do a good job of obfuscating the real issue here. I stand by what I said, and from what I can tell from your jargon filled post you are not disputing any of the substance of what I said. It seems in your first post saying I was wrong, you had missed that I was talking about an extra principle payment. I then laid it out in some nice little example to make sure it was clearer.

I don't think the people here care about mortgage Jargon, they want to know information that they can use to save money. That is what I provided, and I purposefully left out jargon and any undefined TLA (Three Letter acronyms.)

I really don't care what you think, or your ego trip. I did feel a need to respond to you, because my main point is to explain some information that forum members can use to save money when paying off their mortgage. I didn't want forum members to read your very confusing posts saying I was wrong, not know who to believe, and then missing out on a money saving tip.
 
Mini rant........

Does anyone beside me know the difference between principle and principal? It is hard to come across as a financial authority if you don't know the difference. Reminds me of my lawyer having pre-printed documents with the word "judgement" on them. :facepalm:

Rant off.......

Spelling has never been my strong suit, but point taken. Although, just for the record I was not trying to come off as a financial expert. Just trying to pass along a tip I found useful and that I used to save money.

It seems like new people are not welcome here, so I am fine with just going back to lurking.

I would not worry about it... some people here just need to pass judgement on other posts when they do not have much to add to the discussion.

I found your post clear and easy to understand. Wonder if this is the reason some banks let you pick the day of your payment.

Don't take it so hard, I thought you were doing a grand job of explaining your point. Bad spelling and grammar on a forum is kinda like participating in a debate with mustard on your chin.

Brush it off. I have some words that I mix up too. I usually attribute it to my learning disability that was diagnosed just before I got my masters degree. While my eyesight was good, I was eligible for reading for the blind.
You have a much bigger problem with you user name. If you really have OMY syndrome... you'll never retire! :blush: You'll always have OMY.

To the original topic, I don't recall if I used a personal, cashier's or bank check. But I don't recall any website with payoff information. I had to call the bank for the payoff information. But then, that was 1993 and at age 32. I'm sure things have changed... perhaps with the exception of the good feeling knowing that the mortgage is paid off. Congrats! :dance:

Understood. I will NOT take my ball and go home.

Agreed, that is my biggest problem. I will open up a thread in the introduction forum and explain my story. The short version is 5 years ago I set a goal to FIRE in March of 2016. I met the goal for FI, but have decided to stay another year so I can have my kitchen re-done. Classic OMY
 
Wow, giving up a year of [-]life[/-] retirement to remodel your kitchen. You must be one heck of a cook!

No my current kitchen is just that bad:facepalm: from years of LBYM. Although perhaps I am just making an excuse, classic OMY. I should have time to open up a intro thread this weekend. We can dive into my disease there.
