P&I repayment ratio

From: Donna L


Just trying to knock up a spreadsheet.
What percentage do you have to add to
account for a P & I loan repayment
amount. E.g. 200 k loan at 10% equals
20K per year - P & I would be......? What
this as a formula or multiplier based on
25 year loan. Thanks guys

Try the PMT formula.
PMT( 8.55%/12,30*12,80000,0)

If loan is 80k @ 8.55% for 30 years, and the final balance is to be $0, then the monthly payments will be $617.97 per month.

If you're using excel, search in the help file for "home loan". There's
heaps there, and this is the formula you'd need.

Jas

Calculates the payment for a loan based on constant payments and a
constant interest rate.

Syntax

PMT(rate,nper,pv,fv,type)

For a more complete description of the arguments in PMT, see the PV
function.

Rate is the interest rate for the loan.

Nper is the total number of payments for the loan.

Pv is the present value, or the total amount that a series of future
payments is worth now; also known as the principal.

Fv is the future value, or a cash balance you want to attain after the
last payment is made. If fv is omitted, it is assumed to be 0 (zero),
that is, the future value of a loan is 0.

Type is the number 0 (zero) or 1 and indicates when payments are due.

Set type equal to If payments are due
0 or omitted At the end of the period
1 At the beginning of the period

Remarks
The payment returned by PMT includes principal and interest but no
taxes, reserve payments, or fees sometimes associated with loans.
Make sure that you are consistent about the units you use for specifying
rate and nper. If you make monthly payments on a four-year loan at an
annual interest rate of 12 percent, use 12%/12 for rate and 4*12 for
nper. If you make annual payments on the same loan, use 12 percent for
rate and 4 for nper.
Tip

To find the total amount paid over the duration of the loan, multiply
the returned PMT value by nper.

Example 1

The example may be easier to understand if you copy it to a blank
worksheet.

How?

Create a blank workbook or worksheet.
Select the example in the Help topic. Do not select the row or column
headers.


Selecting an example from Help

Press CTRL+C.
In the worksheet, select cell A1, and press CTRL+V.

A B
Data Description
8% Annual interest rate
10 Number of months of payments
10000 Amount of loan
Formula Description (Result)
=PMT(A2/12, A3, A4) Monthly payment for a loan with the above terms
(-1,037.03)
=PMT(A2/12, A3, A4, 0, 1) Monthly payment for a loan with the above
terms, except payments are due at the beginning of the period
(-1,030.16)


Example 2

You can use PMT to determine payments to annuities other than loans.

The example may be easier to understand if you copy it to a blank
worksheet.

How?

headers.

A B
Data Description
6% Annual interest rate
18 Years you plan on saving
50,000 Amount you want to have save in 18 years
Formula Description (Result)
=PMT(A2/12, A3*12, 0, A4) Amount to save each month to have 50,000 at
the end of 18 years (-129.08)


Note The interest rate is divided by 12 to get a monthly rate. The
number of years the money is paid out is multiplied by 12 to get the
number of payments.
