A long-term loan is a type of loan scheduled to be repaid over several years, typically more than one. These loans are integral to both personal finance and business operations, allowing individuals and organizations to spread out large payments over an extended period.
Secured Long-term Loans
These loans are backed by collateral, such as property or other assets. Common examples include mortgages and car loans.
Unsecured Long-term Loans
These loans do not require collateral and typically come with higher interest rates. Examples include personal loans and student loans.
Fixed-rate Long-term Loans
The interest rate remains constant throughout the life of the loan, providing predictable payments.
Variable-rate Long-term Loans
The interest rate can fluctuate based on market conditions, which can result in variable monthly payments.
Amortizing a loan involves calculating the payment amount at regular intervals (usually monthly) over the loan term. The formula is:
$$ M = P \frac{r(1+r)^n}{(1+r)^n - 1} $$
Where:
- \( M \) = Monthly payment
- \( P \) = Principal loan amount
- \( r \) = Monthly interest rate
- \( n \) = Number of payments
Example Calculation
For a $200,000 mortgage at 5% annual interest rate for 30 years:
- Monthly interest rate \( r \) = 0.05 / 12 = 0.004167
- Number of payments \( n \) = 30 \times 12 = 360
$$ M = 200,000 \frac{0.004167(1+0.004167)^{360}}{(1+0.004167)^{360} - 1} $$
$$ M \approx 1,073.64 $$
