How to Calculate Your Monthly Loan Payment
Every payment splits between principal (what you actually borrowed) and interest (what the lender charges). We use the industry-standard amortization formula that every major U.S. lender applies. The widget above runs the exact same math live.
Example: A $30,000 car loan at 7.2% APR for 60 months produces a monthly payment of ~$597. Total interest paid: roughly $5,820. Extend to 72 months and the payment drops to ~$514 but total interest climbs above $7,000. The interactive calculator above shows these trade-offs instantly.
What Is an Amortization Schedule?
It is the month-by-month breakdown of every payment. Early on, you pay mostly interest. Later, the majority goes to principal. Seeing this schedule helps you understand why making extra payments early has an outsized effect.
Our live tool and the app both generate full schedules so you can pick any month and see the exact remaining balance.
How Extra Payments Cut Interest
Even modest extra payments applied consistently attack the principal faster. The live calculator above shows the precise months saved and interest avoided. From user data, most people who add even $50–$100 extra per month on auto loans finish 8–14 months earlier.
Comparing Two Loan Offers Side by Side
One of the most powerful features is the Loan Comparison tool. Enter two different sets of loan terms — Loan A and Loan B — and the calculator displays the monthly payment, total interest, and total repayment for each. This is useful when you have quotes from two lenders, or when you are deciding between a shorter and a longer loan term. The lower payment is not always the better deal; the comparison shows you the real cost of each option over time.
Refinance Break-Even: Is It Worth It?
Refinancing can lower your monthly payment or save interest — but it comes with closing costs. The Refinance Break-Even calculator figures out how many months it takes for your monthly savings to offset those upfront costs. If your break-even point is 18 months and you plan to stay in the home for 5 years, refinancing likely makes sense. If you plan to sell in a year, the math may not work in your favor.
