Understanding Loan Formulas
Loans are calculated using two main formulas:
Monthly Payment Formula
M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ]
Where:
- M = Monthly payment
- P = Principal loan amount
- i = Monthly interest rate (APR/12/100)
- n = Number of payments (loan term in years × 12)
Total Interest Formula
Total Interest = (M × n) - P
The calculator applies these formulas to provide accurate results based on your inputs.
Different Types of Loans
There are several common loan types, each with different repayment structures:
Fixed-Rate Loans
Interest rate remains constant throughout the loan term. Monthly payments stay the same.
Variable-Rate Loans
Interest rate can change based on market conditions. Monthly payments may vary.
Interest-Only Loans
Only interest is paid for a set period, with principal repaid at the end.
Our calculator works with fixed-rate loans, which are the most common type.
Practical Loan Examples
Let's look at two common loan scenarios:
Example 1: $200,000 Mortgage
For a $200,000 mortgage at 4.5% APR over 30 years:
- Monthly payment: $1,143.55
- Total interest: $283,062
- Total repayment: $483,062
Example 2: $10,000 Personal Loan
For a $10,000 personal loan at 8% APR over 5 years:
- Monthly payment: $194.34
- Total interest: $1,156
- Total repayment: $11,156
These examples show how different loan amounts and terms affect your monthly payments and total interest.
Frequently Asked Questions
What is the difference between APR and interest rate?
APR (Annual Percentage Rate) is the total annual cost of borrowing, including fees. The interest rate is the actual percentage charged on the loan amount. APR is always higher than the interest rate.
How does loan term affect my payments?
A longer loan term means lower monthly payments but more total interest paid. A shorter term means higher monthly payments but less total interest. Choose based on your budget and financial goals.
Can I pay extra toward my loan?
Yes, paying extra principal reduces your loan balance faster and saves on interest. Our calculator shows how extra payments affect your repayment timeline.
