What is a one-sentence summary of the following article?
Create labels for your data in the first column to keep things organized. Here's what you should put in each cell:  .  A1: Loan Amount  A2: Interest Rate  A3: Months  A4: Payments Fill out cells B1-B3 with information about your loan. Leave B4 (the cell next to the Payments label) blank.  The "Months" value should be the total number of months in the loan term. For example, if you have a 2-year loan, enter 24. The "Interest Rate" value should be a percentage (e.g., 8.2%). To do this, click cell B4, and then type the following formula into the formula (fx) bar at the top of the sheet and then press ↵ Enter or ⏎ Return: =ROUND(PMT($B$2/12,$B$3,-$B$1,0), 2).  The dollar signs in the formula are absolute references to make sure the formula will always look to those specific cells, even if it is copied elsewhere into the worksheet. The loan interest rate must be divided by 12, since it is an annual rate that is calculated monthly. For example, if your loan is for $150,000 at 6 percent interest for 30 years (360 months), your loan payment will calculate out to $899.33. You'll be adding some additional data to the sheet, which requires a second chart area. Enter the following labels into the cells:  A7: Period  B7: Beginning Balance  C7: Payment  D7: Principal  E7: Interest  F7: Cumulative Principal  G7: Cumulative Interest  H7: Ending Balance. This column will contain your payment dates. Here's what to do:  Type the month and year of the first loan payment in cell A8. You may need to format the column to show the month and year correctly. Click the cell once to select it. Drag down from the center of the selected cell downward to cover all cells through A367. If this doesn't make all of the cells reflect the correct monthly payment dates, click the small icon with a lightning bolt on it at the bottom-right corner of the bottommost cell and make sure the Last Month option is selected. The beginning balance of your loan into cell B8. In cell C8, type =$B$4 and press Enter or Return. In cell E8, create a formula to calculate the loan interest amount on the beginning balance for that period. The formula will look like =ROUND($B8*($B$2/12), 2). The single dollar sign creates a relative reference. The formula will look for the appropriate cell in the B column. In cell D8, subtract the loan interest amount in cell E8 from the total payment in C8. Use relative references so this cell will copy correctly. The formula will look like =$C8-$E8. In cell H8, create a formula to subtract the principal portion of the payment from the beginning balance for that period. The formula will look like =$B8-$D8. Cell B9 should include a relative reference to the ending balance of the prior period. Type =$H8 into B9 and press Enter or Return. Copy cells C8, D8 and E8 and paste them into C9, D9 and E9 (respectively) Copy H8 and paste it into H9. This is where the relative reference becomes helpful. In cell F9, create a formula to tabulate cumulative principal paid. The formula will look like this: =$D9+$F8. Enter the cumulative interest formula into G9 like this: =$E9+$G8. When you rest the mouse cursor over the bottom-right part of the highlighted area, the cursor will turn to a crosshair. This populates all the cells through row 367 with the amortization schedule. If this looks funny, click the small spreadsheet-looking icon at the bottom-right corner of the final cell and select Copy Cells.

Summary:
Open a new spreadsheet in Microsoft Excel. Create labels in column A. Enter the information pertaining to your loan in column B. Calculate your payment in cell B4. Create column headers in row 7. Populate the Period column. Fill out the other entries in cells B8 through H8. Continue the schedule by creating the entries in B9 through H9. Highlight cells B9 through H9. Drag the crosshair all the way down to row 367.
