### Lab Exercise 8: Creating an Amortization Table
**Objective:** Learn how to create an amortization table that shows the breakdown of each monthly payment into principal and interest over a 5-year term, using multiple sheets in Excel.
**Instructions:**
1. **Open a New Excel Workbook:**
- Create a new Excel workbook for this lab.
2. **Create the "Loan Details" Sheet:**
- Rename the first sheet to "Loan Details".
- Enter the following loan details into your "Loan Details" sheet:
| Loan | Principal | Term (Years) | Annual Interest Rate |
| ------ | --------- | ------------ | -------------------- |
| Loan 1 | 50000 | 5 | 5% |
3. **Create the "Amortization Table" Sheet:**
- Add a new sheet and rename it to "Amortization Table".
- Set up the amortization table headers in the "Amortization Table" sheet:
| Period | Payment | Principal Paid | Interest Paid | Remaining Balance |
| ------ | ------- | -------------- | ------------- | ----------------- |
4. **Calculate Monthly Payment:**
- In the "Loan Details" sheet, calculate the monthly payment using the PMT function.
- **Formula in cell B5 (or any cell you choose):** `=PMT(D2/12, C2*12, -B2)`
5. **Link Monthly Payment to "Amortization Table" Sheet:**
- In the "Amortization Table" sheet, reference the monthly payment from the "Loan Details" sheet.
- **Formula in cell B2:** `='Loan Details'!B5`
6. **Fill in the Amortization Table:**
- In the "Amortization Table" sheet:
- In the first row under Period, enter 1.
- In the Payment column, reference the monthly payment from cell B2.
- **Formula in cell B2:** `='Loan Details'!B5`
- For Principal Paid, use the PPMT function.
- **Formula in cell C2:** `=PPMT('Loan Details'!D2/12, A2, 'Loan Details'!C2*12, -'Loan Details'!B2)`
- For Interest Paid, use the IPMT function.
- **Formula in cell D2:** `=IPMT('Loan Details'!D2/12, A2, 'Loan Details'!C2*12, -'Loan Details'!B2)`
- For Remaining Balance, subtract the principal paid from the previous remaining balance.
- **Formula in cell E2:** `='Loan Details'!B2 + SUM(C$2:C2)`
7. **Copy Formulas Down:**
- Copy the formulas down for all periods (1 to 60) to complete the amortization table.
### Example Data in Excel:
**Loan Details Sheet:**
| A | B | C | D |
| ------ | --------------- | ------------------------ | -------------------- |
| Loan | Principal | Term (Years) | Annual Interest Rate |
| Loan 1 | 50000 | 5 | 5% |
| | | | |
| | Monthly Payment | =PMT(D2/12, C2\*12, -B2) | |
**Amortization Table Sheet:**
| Period | Payment | Principal Paid | Interest Paid | Remaining Balance |
| ------ | ------------------ | -------------------------------------------------------------------------- | -------------------------------------------------------------------------- | ------------------------------- |
| 1 | ='Loan Details'!B5 | =PPMT('Loan Details'!D2/12, A2, 'Loan Details'!C2\*12, -'Loan Details'!B2) | =IPMT('Loan Details'!D2/12, A2, 'Loan Details'!C2\*12, -'Loan Details'!B2) | 'Loan Details'!B2 + SUM(C$2:C2) |
| 2 | ='Loan Details'!B5 | =PPMT('Loan Details'!D2/12, A3, 'Loan Details'!C2\*12, -'Loan Details'!B2) | =IPMT('Loan Details'!D2/12, A3, 'Loan Details'!C2\*12, -'Loan Details'!B2) | E2 - C3 |
| 3 | ='Loan Details'!B5 | =PPMT('Loan Details'!D2/12, A4, 'Loan Details'!C2\*12, -'Loan Details'!B2) | =IPMT('Loan Details'!D2/12, A4, 'Loan Details'!C2\*12, -'Loan Details'!B2) | E3 - C4 |
