This post provides instruction for you to create a Mortgage Excel sheet where you can work out payments including interest and principal payments of a home loan (table loan type), based on PMT, IPMT and PPMT functions.

Create the Mortgage Excel sheet

Name the sheet “Mortgage” and enter values as below:

CellValueCellValue
A1TypeA2Fixed 12 months
B1Loan AmountB2$100,000
C1Term (years)C210
D1Repayment FrequencyD2Fortnightly
E1Number of Payments Per YearE226
F1Interest RateF25.00%
G1Fortnight PaymentG2=-PMT(F2/E2, C2*E2,B2)

To see the details of how much interest, principal and the balance on each fortnight, you can create a detail table as below:

CellValueCellValue
A12FortnightA131
B12PaymentB13=ROUND($G$2,2)
C12InterestC13=-IPMT($F$2/$E$2,A13,$C$2*$E$2,$B$2)
D12PrincipalD13=-PPMT($F$2/$E$2,A13,$C$2*$E$2,$B$2)
E12BalanceE13=B2-D13
A142E14=E13-D14

Next, select the range A13:A14 and drag down to cell A272 (Tip: move the mouse cursor to the right bottom corner of cell A14 until the mouse cursor turns to a + sign then drag down). Cell A272 now should have the value 260.

After that, select range B13:D13 and copy down the formula until row 272 ((Tip: move the mouse cursor to the right bottom corner of cell D13 until the mouse cursor turns to a + sign then double click)

Finally, select cell E14, move the mouse cursor to the right bottom corner of the cell until the mouse cursor turns to a + sign then double click to copy down the formula. Cell E272 should have the value of 0.00.

Congratulations, now you have a mortgage Excel sheet to work out and keep track of payments, principals, interests and balances.

Your sheet should look like the screenshot below:
