Question

To determine how much you'll end up paying for a **\$40,000 student loan at a 4% annual interest rate**, we'll need to consider the **repayment term**, which is the length of time you have to repay the loan. The total amount you pay depends significantly on this term.

### Common Repayment Terms
1. **10-Year Term (120 months)**
2. **20-Year Term (240 months)**
3. **30-Year Term (360 months)**

Let's explore the **10-year repayment plan**, which is a common standard for student loans.

### Assumptions:
- **Loan Amount (Principal):** \$40,000
- **Annual Interest Rate:** 4%
- **Repayment Term:** 10 years (120 months)
- **Compounding:** Monthly

### Calculations

1. **Monthly Interest Rate (r):**
   $$
   r = \frac{4\%}{12} = 0.3333\% \text{ or } 0.003333 \text{ (decimal)}
   $$

2. **Number of Payments (n):**
   $$
   n = 10 \text{ years} \times 12 \text{ months/year} = 120 \text{ months}
   $$

3. **Monthly Payment (M):**
   
   The formula for the monthly payment on an installment loan is:
   $$
   M = P \times \frac{r \times (1 + r)^n}{(1 + r)^n - 1}
   $$
   Where:
   - $$ P $$ = Principal (\$40,000)
   - $$ r $$ = Monthly interest rate (0.003333)
   - $$ n $$ = Total number of payments (120)
   
   Plugging in the numbers:
   $$
   M = 40,000 \times \frac{0.003333 \times (1 + 0.003333)^{120}}{(1 + 0.003333)^{120} - 1}
   $$
   
   Calculating $$(1 + 0.003333)^{120}$$:
   $$
   (1.003333)^{120} \approx 1.4908
   $$
   
   Now, compute the payment:
   $$
   M \approx 40,000 \times \frac{0.003333 \times 1.4908}{1.4908 - 1} \approx 40,000 \times \frac{0.004969}{0.4908} \approx 40,000 \times 0.01012 \approx \$404.80
   $$
   
   **Monthly Payment:** Approximately **\$405**

4. **Total Payment Over 10 Years:**
   $$
   \text{Total Payment} = M \times n = 405 \times 120 = \$48,600
   $$

5. **Total Interest Paid:**
   $$
   \text{Total Interest} = \text{Total Payment} - \text{Principal} = 48,600 - 40,000 = \$8,600
   $$

### Summary for a 10-Year Term:
- **Monthly Payment:** ~\$405
- **Total Payment Over 10 Years:** ~\$48,600
- **Total Interest Paid:** ~\$8,600

### Other Repayment Terms
If you choose a different repayment term, the numbers will change:

- **20-Year Term (240 months)**
  - **Monthly Payment:** ~\$242
  - **Total Payment:** ~\$58,080
  - **Total Interest:** ~\$18,080

- **30-Year Term (360 months)**
  - **Monthly Payment:** ~\$191
  - **Total Payment:** ~\$68,760
  - **Total Interest:** ~\$28,760

### Important Considerations
- **Interest Accumulation:** The longer the repayment term, the more interest you'll pay over the life of the loan.
- **Affordability:** While longer terms reduce monthly payments, they increase total interest.
- **Prepayment:** Making extra payments can reduce both the principal and the total interest paid.
- **Loan Forgiveness or Assistance Programs:** Some programs may affect the total amount you owe based on eligibility.

### Conclusion
If you **repay a \$40,000 student loan at a 4% interest rate over 10 years**, you'll pay approximately **\$48,600** in total, which includes **\$8,600** in interest. Adjusting the repayment term will affect both your monthly payments and the total amount paid over the life of the loan.
If you repay a \$40,000 student loan at a 4% interest rate over 10 years by paying the minimum each month, you'll end up paying approximately \$48,600 in total, which includes \$8,600 in interest.
