Loan Shopping Guide

How to Compare Loan Offers

Most borrowers compare interest rates -- but the rate alone can be misleading. Here is the complete checklist for evaluating any loan offer correctly.

Shopping multiple lenders is one of the most impactful financial decisions you can make -- but only if you know what you are comparing. Two offers with the same interest rate can have very different true costs. Here is how to do it right.

Start with APR, Not the Interest Rate

The Annual Percentage Rate (APR) includes the interest rate plus origination fees, points, and other lender costs -- expressed as a single percentage. It is the closest thing to a "true cost" comparison across lenders.

A lender offering 6.75% with $3,000 in fees might have a higher APR than one offering 7.00% with zero fees, depending on the loan amount and term. Always compare APR not just the interest rate.

APR > Interest Rate --> lender is charging fees
APR = Interest Rate --> typically a no-fee loan

Use the Loan Estimate (for Mortgages)

Federal law requires mortgage lenders to issue a standardized Loan Estimate within three business days of your application. This document makes it straightforward to compare lenders line by line -- interest rate, APR, monthly payment, closing costs, and cash to close are all shown in the same format across every lender.

Key sections to compare:

Page 1 Loan Terms: rate, monthly payment, prepayment penalty, balloon payment
Page 2 Closing Cost Details: origination charges, appraisal, title, escrow
Page 3 Comparisons: APR and total interest paid over life of loan

For Personal and Auto Loans: What to Ask

Non-mortgage lenders are not required to issue a Loan Estimate. Build your own comparison checklist:

APR the all-in rate including fees
Origination fee typically 1%-8% of the loan on personal loans; some lenders charge zero
Loan term longer terms lower payments but raise total interest paid; see What Is a Loan Term?
Prepayment penalty does paying off early cost you? See What Is a Prepayment Penalty?
Late payment fee what happens if you miss a payment?
Autopay discount many lenders offer 0.25% rate reduction for autopay enrollment

Total Cost of Borrowing: The Real Number

Monthly payment comparisons are misleading if the loan terms differ. A $250/month payment on a 7-year auto loan costs far more total interest than a $300/month payment on a 5-year loan. The only honest comparison is total interest paid over the life of the loan.

Compare on the Same Day

Interest rates change daily with market conditions. Getting quotes from multiple lenders on the same day ensures you are comparing the same market environment. A quote from Monday and a quote from Friday of the same week could reflect very different rate conditions, especially during volatile markets.

Rate Shopping and Your Credit Score

Multiple mortgage inquiries within a short window (typically 14-45 days depending on the scoring model) count as a single inquiry. For auto and personal loans, the window is typically 14-30 days. Rate shopping aggressively within this window has minimal impact on your score -- do not let fear of credit pulls stop you from shopping properly.

Fixed vs Adjustable Rate

A fixed-rate loan has the same rate for the full term. An adjustable-rate mortgage starts lower and adjusts periodically. Never compare a fixed offer to an ARM offer at face value -- the ARM's initial rate is artificially low. Compare the total cost over your expected holding period, not just the current monthly payment.

Loan Comparison Checklist

Factor	Why It Matters
APR	True all-in cost including fees
Total interest over term	The only honest lifetime comparison
Monthly payment	Must fit your budget -- but do not optimize for payment alone
Loan term	Longer = lower payment, higher total cost
Origination fee	May make a low-rate offer more expensive
Prepayment penalty	Limits your ability to pay off early
Rate type (fixed/ARM)	Fixed = certainty; ARM = risk
Autopay discount	Free 0.25% rate reduction on many loans

Frequently Asked Questions

What is the most important number when comparing loans?

APR -- Annual Percentage Rate -- is the single most important number because it includes both the interest rate and lender fees (origination charges, points, broker fees) expressed as one annualized figure. A lender quoting a 6.5% rate with a 2% origination fee has a higher APR than one quoting 7.0% with no fees, depending on loan term. The Truth in Lending Act requires all lenders to disclose APR, and the standardized Loan Estimate form makes comparing it straightforward. Never compare offers using only the stated interest rate.

What is a Loan Estimate and how do I use it?

A Loan Estimate is a standardized three-page form required by the CFPB that lenders must provide within three business days of receiving a mortgage application. It shows your estimated rate, monthly payment, closing costs, APR, and total cost over five years in a consistent format across all lenders. To compare multiple offers, request Loan Estimates from each lender on the same day (so rate conditions are the same), then compare Section A (origination fees), Section B/C (third-party fees), the APR, and the five-year cost figure. Minor differences in Section B/C costs are often negotiable.

How many loan offers should I get?

Consumer Financial Protection Bureau research shows that getting just one additional quote saves the average mortgage borrower $1,500 over the loan's life, and getting five quotes saves $3,000 on average. The recommendation is a minimum of three to five lenders: include your current bank, a credit union, an online lender, and a mortgage broker (who can shop multiple lenders simultaneously). Rate shopping for mortgages within a 14 to 45-day window counts as a single credit inquiry, so multiple applications do not meaningfully hurt your credit score.

What fees are negotiable on a loan?

Origination fees, discount points, and application fees charged by the lender (Section A of the Loan Estimate) are the most negotiable. Title insurance, escrow fees, and attorney fees (Section C) vary by provider and can sometimes be shopped independently. Third-party fees like appraisal are generally not negotiable. When comparing offers, a lender offering a lower rate but higher origination fees may cost more overall than one with a slightly higher rate and lower fees -- calculate total cost including all fees to make a fair comparison.

Should I lock my rate when comparing offers?

Do not lock until you have selected a lender and are confident in your decision. Rate locks typically last 30 to 60 days and involve a commitment to that lender. Once locked, switching to a different lender means starting over and potentially losing your lock deposit. Complete your comparison, select the best offer, then lock. In a rising rate environment, lock as soon as you decide -- even a day's delay can change your rate. In a stable or declining rate environment, you have more flexibility on timing.
