LoanCalcTools is a set of free calculators for the money decisions that turn on a few numbers: loans, mortgages, auto loans, personal loans, refinancing, APR, debt payoff, compound interest and inflation. Enter your figures, see the payment, the total interest or the equivalent value, and understand the real cost before you sign.
The idea behind the site is simple. The math under most borrowing decisions is published and standard, but it is tedious to do by hand and easy to get wrong in a spreadsheet. A calculator that uses the right formula, and shows the worked example next to it, lets you check a lender's quote and compare offers on your own terms.
LoanCalcTools is owned and operated by Chris Terry through Encore Promotional Products, as part of the Encore Editorial network of free tools and reference sites. We are not a lender, a broker, or a lead-generation service you have to register with. The tools are open to anyone, with no sign-up and nothing stored. See the authors page for who writes and reviews the guides on this site, and what each of them checks before publishing.
Every tool uses the standard, published formula for its job rather than a house shortcut. Loan, auto, mortgage, personal loan and refinance payments use the amortization formula, M = A·i / (1 - (1 + i)^-n), where A is the amount, i the monthly rate and n the number of payments. The APR tool follows the cost-of-credit method behind the Truth in Lending Act, solving for the rate that equals the money you actually receive after fees. The debt payoff tool steps through the balance month by month the way a statement does. The inflation tool uses the Bureau of Labor Statistics Consumer Price Index. We check these against primary sources and cite them on each page. The full method is on our editorial standards page.
Results are estimates for planning, not financial advice or an offer of credit. They show principal and interest, or the figure each tool is built for, and they assume the inputs you enter. A real loan can cost more once you add fees, insurance or a changing escrow, and a real investment return varies year to year. For any major decision, confirm the exact terms with your lender and, where it matters, a qualified professional.
Guides carry a byline with an updated date, calculators carry the date they were last checked, and the rates dataset states the observation date next to every figure it quotes. Mortgage averages follow Freddie Mac's weekly survey; personal loan, auto and card averages follow the Federal Reserve's monthly G.19 release, so those pages move on their sources' schedule rather than ours. When a reader reports a wrong number through the contact form, the fix ships the same week and gets noted on the page instead of slipped in quietly.
The site is free because it carries advertising and a small number of affiliate links. If you click an affiliate link and complete a purchase, we may earn a commission at no additional cost to you. That revenue never changes the formula a calculator uses or the figure it returns, and we do not take payment to alter a result or push a product. The affiliate disclosure appears at the bottom of every page.
