Loans: how they work and what they really cost

Most loan decisions come down to three numbers: the APR, the monthly payment and the total you will repay. This hub explains how to compare them, and each calculator below runs one of those numbers for you in your browser.

Start with the number that matters

A lender's headline rate is only part of the story. Fees, term length and the way interest accrues all change what you pay. When you compare two offers, put them on the same footing first: the same amount, the same term, and the APR written on the disclosure rather than the rate on the advertisement.

Once the basics line up, look at the monthly payment to see whether the loan fits your budget, then at the total repaid to see what the loan costs. A lower payment is only a bargain if the total stays reasonable.

The guides below go deeper on each step, from amortization and debt-to-income to refinancing and term length.

Before you borrow: a checklist

  1. Write down the exact amount you need, not the amount a lender offers.
  2. Get the APR, fees, term and prepayment rules for at least two offers in writing.
  3. Run the payment and total repaid with a calculator, using each offer's real numbers.
  4. Check that the payment fits your budget with room for an emergency.
  5. Read the late-payment and default terms before you sign.

Loan questions, answered

Which number should I compare when choosing a loan?

Compare the APR, not only the interest rate. APR includes most upfront fees, so it shows the true yearly cost. Then compare total repayment for the same amount and term.

Is a longer loan term always more expensive?

A longer term lowers the monthly payment but usually raises total interest, because the balance stays outstanding for more months. Compare the total repaid across the terms you can afford.

What is the difference between prequalification and preapproval?

Prequalification is a rough estimate based on information you provide, often with a soft credit check. Preapproval may involve more verification and a conditional offer. These terms are not standardized: ask the lender whether a credit check is soft or hard before agreeing.

How do I know if I can afford a new loan?

Lenders look at your debt-to-income ratio, which is your monthly debt payments divided by gross monthly income. There is no single cutoff for all loans. Also check your take-home budget: gross-income ratios do not account for all living costs.
