What Is This Tool?
The Loan Calculator works out the cost of borrowing. Enter the loan amount, interest rate, and term in years and months, and it returns your periodic payment along with the total of all payments and the total interest. Options let you set how often interest compounds and how often you pay it back. A donut chart splits principal from interest, a line chart tracks the balance over time, and a full amortization schedule shows every payment. The result can be downloaded as a PDF.

Frequently Asked Questions
- What's the difference between compounding and payback frequency?
- Compounding frequency is how often interest is added to the balance; payback frequency is how often you make a payment.
- Why is so much of an early payment interest?
- Interest is charged on the outstanding balance, which is highest at the start, so early payments are mostly interest.
- How can I reduce the total interest?
- Choose a shorter term or a lower rate; both reduce the interest paid over the life of the loan.
- What does 'continuously' compounding mean?
- It's the theoretical limit of compounding at every instant, giving the highest effective rate for a given nominal rate.
Key Terminology
- Principal
- The amount borrowed, before interest is added.
- Interest
- The cost of borrowing, charged as a percentage of the balance.
- Compounding frequency
- How often interest is added to the outstanding balance.
- Payback frequency
- How often a repayment is made on the loan.
- Amortization
- Paying off a loan through scheduled payments that cover interest and principal.
