The Formulas Behind the Magic
Our calculator uses industry-standard financial formulas to provide you with accurate and insightful results. Understanding these can give you a deeper appreciation for how loans and investments work.
Monthly Payment (PMT) Formula
To calculate the fixed monthly payment for a loan, we use the following amortization formula:
- PMT = Your fixed monthly payment.
- P = The principal loan amount.
- r = The monthly interest rate. We calculate this by dividing the annual rate by 12.
- n = The total number of payments (loan term in months).
Compound Interest Formula
For understanding the growth of an investment or the total amount paid on a loan, the compound interest formula is key:
- A = The future value of the investment/loan, including interest.
- P = The principal amount.
- r = The annual interest rate (as a decimal).
- k = The number of times that interest is compounded per year (e.g., 12 for monthly).
- t = The number of years the money is invested or borrowed for.

5. FAQs
Q1: What is the difference between principal and interest?
The principal is the initial amount of money you borrow for a loan or invest. The interest is the cost of borrowing that money, or the profit you earn for investing it, typically expressed as a percentage rate.
Q2: How does a longer loan term affect my payments?
A longer loan term will typically result in lower monthly payments, but you will end up paying significantly more in total interest over the life of the loan. A shorter term means higher monthly payments but less total interest paid.
Q3: What is an amortization schedule?
It’s a detailed table that lists each payment for a loan over its entire term. It breaks down how much of each payment goes towards interest and how much goes towards reducing your principal balance.
Q4: Can I use this calculator for investments?
Yes! While many examples focus on loans, the underlying compound interest calculations are perfect for forecasting investment growth. Simply enter your initial investment as the principal, the expected annual return as the interest rate, and the investment period as the term.
Q5: Are the calculations from this tool 100% accurate?
Our calculator uses standard, proven financial formulas to provide highly accurate estimates for planning purposes. However, your actual loan from a financial institution may have slightly different figures due to fees, specific insurance costs, or different rounding methods. Always consult your official loan documents for exact figures.
