I'm trying to create a formula for a truck loan using =PMT but I can't seem to get it to work correctly.   I want the formula to use the Loan amount with the monthly interest rate (beginning of month), a regular payment, and and extra payment on the principal, and figure the number of months left on the loan and the payoff date.

I am fairly new to Excell and am studying the Excel lessons which are great and a little slow with this stuff but I created a Payoff schedule file which is working great except for these new enhancements I've just added.   Anybody has any ideas I'm sure listening......Thanks!!!

 

LENDER BEGINNING SCHEDULED DATE ACCELERATED   Months: PayOff Date: NAME BALANCE PAYMENT PAID PAYMENT       Centris CFU - Ford Truck              21,084.08  $                388.92                    111.08           3701 August 16, 2322

                                                                                                              Formula for months left on loan (Months) =PMT(2.53/12,6*12,21255.29,0,1)

                                                                                                              Formula for figuring the PayOff Date                                           =DATE(2014,3-M7,16)

The PMT function is used to calculate the payment amount for a loan, but it seems that in this case you know the payment amount and want to calculate the number of periods.

To do this, you need to use the NPER function instead of the PMT function.

 

The NPER function is almost exactly the same as the PMT function, but it extracts the number of periods instead of the payment amount.  You can also use the PV and RATE functions to calculate the present value and interest rate of a loan if you have the other values.

 

The PMT function is covered in the PDF and video lesson: Expert Skills Lesson 3-3: Use the formula palette and the PMT function.

Each of the four functions works in a very similar way, so I would recommend starting here and making sure that you completely understand the PMT function.

 

I have attached an example spreadsheet.  Your example data was a little hard to read, so I'm not sure if I have it exactly right, but hopefully this will offer a good starting point and example of how to use the NPER function:

The formula to return the number of months is: =NPER((E2/12),C2,-B2)

 

If you need more assistance, please feel free to attach your spreadsheet and I will take another look.

Thank you very much this helps a great deal.    Below is part of the spreadsheet I'm working on, here is a little history of it.     Ok, B5 is the amount owed, C5 is the payment with E5 as the extra payment on the principal, G5 is balance of loan after all payments are made, H5 of course is interest Rate (APR), I5 Months left to pay and J5 should read the actual date the loan will be paidoff.  (Note:  F5 will read the same as B5 unless there is a Date in D5 then C5 & E5 will be subtracted from B5 then I5 should change to current months left and J5 as payoff date calculated from the date in D5 or the current date shown in D2.....)

Wow...I got it figured out,   Lesson 3-11 in Expert Skills Section explained the =DATE(Year),(Month)+months left to pay,(Day) function and it works perfect

 

=DATE(YEAR(D7),MONTH(D7)+58,DAY(D7))   Note:   Using the DatePaid field plus the months left to payoff loan, just what I was looking for.   Absolutely outstanding!!!!  Thanks for your help..
