About Quick Loan Calculators
Free online loan calculators for everyone
Why we built this
Most loan decisions start with the same question: what will this cost me each month? Quick Loan Calculators exists to answer it quickly, before you ever talk to a lender.
A lot of loan calculators online are lead-generation forms in disguise. You type in a loan amount, hit "calculate," and land on a page asking for your phone number before it shows you anything. We built the opposite. Every result on this site appears immediately, and we never ask who you are.
The site started with a handful of mortgage and auto loan calculators. It has since grown to more than 40 free calculators, from basic monthly payment tools to narrower ones like SBA loan payments and DSCR ratios for rental property investors. Each calculator comes with educational content explaining how that loan type works, what affects the rate you're offered, and what to watch out for in the fine print.
How the calculators work
Every calculation runs in your browser. When you enter a loan amount, rate, or term, the math happens on your own device. Nothing gets sent to our servers, so we can't collect, store, or share your inputs even if we wanted to.
The formulas are the same ones banks and credit unions use. For a fixed-rate loan, the monthly payment is P[r(1+r)^n]/[(1+r)^n - 1], where P is the principal, r is the monthly interest rate, and n is the number of payments. Each calculator page has its own methodology section spelling out the assumptions behind the numbers.
The calculators are grouped into eight categories: mortgage and home loans, auto financing, personal loans, student loans, business and SBA loans, credit and debt tools, real estate investing, and general loan tools. Where it makes sense, a calculator also shows a full amortization schedule and a payment breakdown chart.
Editorial standards
When we describe loan programs, eligibility rules, or typical rate ranges, we work from primary sources: the Consumer Financial Protection Bureau (CFPB), the U.S. Small Business Administration, the Department of Veterans Affairs, the Federal Housing Administration, and individual lender disclosures. Getting the details right matters more to us than covering every topic.
Loan programs change. Rates change faster. We review our content periodically and update it when a program changes or new data comes out, and each calculator page shows the date it was last reviewed. If you spot something outdated or wrong, tell us through our Contact page.
We do not give personalized financial advice. The content here explains how loan products generally work and what questions to ask your lender. For decisions specific to your own finances, talk to a licensed financial advisor or loan officer.
Accuracy and limitations
Given the same inputs, our results should closely match what a lender quotes you, because we use the same standard formulas for monthly payments, amortization schedules, and total interest.
The inputs are the catch. A lender prices your actual loan on your credit score, income, employment history, and the specific property or asset being financed, plus market conditions and any discount points you buy. A calculator can't know those things in advance. Treat the results as informed estimates, not guaranteed offers.
We are not a lender, broker, or financial advisor. Quick Loan Calculators is a free educational resource. Always verify terms with your lender before making borrowing decisions.
How we make money
Quick Loan Calculators is free to use. Hosting, development, and content are paid for by advertising: we display ads through Google AdSense, and some pages may include links to lender or financial product websites that pay us a referral fee if you apply.
Advertising keeps the site running, but it has no effect on calculator results. The math is the math. We don't adjust outputs to favor any lender, and we don't gate results behind a lead form. If a calculator shows you a $1,847 monthly payment, that comes from the numbers you entered and the standard amortization formula, nothing else.
We also don't rank or recommend specific lenders. When our content mentions FHA loans, VA loans, or SBA programs, it's describing the government programs themselves, not endorsing any particular lender that offers them.

Questions, feedback, and corrections all go through our Contact page. We typically respond within two business days.
