How to Read a Loan Estimate: The 3 Numbers That Actually Matter

Within three business days of applying for a mortgage, your lender is required to send you a Loan Estimate. It's a standardized three-page document that lays out the terms of the loan you're being offered.

Most buyers glance at the interest rate, feel a vague sense of confusion about everything else, and move on.

That's a costly habit. The Loan Estimate contains everything you need to compare lenders accurately, spot hidden costs, and know whether the loan being offered is actually competitive. You just need to know where to look.

Here are the three numbers that tell the real story.

Page one of your Loan Estimate shows two rates side by side. Most buyers only notice the first one.

The interest rate is the base cost of borrowing the money. It determines your principal and interest payment each month.

The APR, or annual percentage rate, is the broader cost of the loan expressed as a rate. It folds in the interest rate plus most lender fees, including origination charges and certain closing costs, spread across the life of the loan.

Here's why both matter. A lender can quote you a very attractive interest rate while loading the loan with fees that make it significantly more expensive than a competing offer with a slightly higher rate. The APR exposes that gap.

If two lenders quote you the same interest rate but meaningfully different APRs, the one with the higher APR is charging more in fees. If one lender's APR is notably higher than their rate, that spread is worth asking about directly.

The APR is an imperfect measure for short-term homeowners because it assumes you hold the loan for its full term. But as a comparison tool across lenders quoting similar products, it's the most honest single number on the page.

This is the number that surprises buyers most often, and the one that causes the most last-minute stress.

Cash to close is found on page two of the Loan Estimate under the "Calculating Cash to Close" section. It represents the total amount of money you need to bring to closing, not just your down payment.

Cash to close includes your down payment plus closing costs, minus any lender credits you've been offered and minus any earnest money you've already paid. The final number is what actually needs to come out of your bank account on closing day.

Closing costs on a typical Washington State purchase run between 2% and 4% of the loan amount. On a $450,000 loan, that's $9,000 to $18,000 on top of your down payment. Many buyers discover this number for the first time when they receive the Loan Estimate, which is far too late to plan around it.

When comparing lenders, look at cash to close, not just the rate. A lender offering a slightly lower rate but $4,000 more in fees may cost you more at the table than a competitor who quoted a rate a fraction higher.

This one lives on page three and almost nobody looks at it. It's called the Total Interest Percentage, or TIP, and it's the most honest long-term cost number on the document.

TIP shows the total amount of interest you'll pay over the life of the loan as a percentage of the loan amount, assuming you keep the loan for its full term.

On a 30-year loan, TIP figures often range from 60% to over 100%. That means on a $400,000 loan, you could pay $240,000 to $400,000 or more in interest over 30 years if you never refinance or sell.

This number is not designed to scare you. It's designed to give you a complete picture of what you're agreeing to, so you can make informed decisions about loan term, rate, and points.

A 15-year loan will have a dramatically lower TIP than a 30-year loan at the same rate. A loan where you bought discount points will have a lower TIP than one where you didn't, assuming you stay long enough for the break-even to pass. Comparing TIP across loan scenarios makes those tradeoffs visible in a single number.

The Loan Estimate is standardized, which is its greatest strength for comparison purposes. But there are a few things it won't reveal on its own.

It doesn't tell you how competitive the rate is relative to the current market. You need to shop at least two or three lenders to establish that baseline.

It doesn't reflect your final costs. Some numbers on the Loan Estimate can change before closing. Lender fees and your rate are typically locked once you choose a lender and lock your rate. Third-party fees, like title insurance and escrow, can shift. The Closing Disclosure you receive three days before closing is the final version.

It also doesn't account for your post-closing financial picture. A loan with low cash to close but a higher rate may preserve liquidity at the cost of a higher payment for 30 years. A loan with higher upfront costs may save you more over time. Neither choice is automatically right. The right answer depends on how long you plan to stay, how much cash you want to keep in reserve, and what you plan to do with that cash if you keep it.

The cleanest approach is to apply with two or three lenders on the same day or within the same 45-day window, so the credit inquiries are treated as a single inquiry by the credit bureaus.

Once you have Loan Estimates from each lender, compare them on the same three numbers: APR, cash to close, and TIP. If one lender looks better on all three, the decision is straightforward. If the tradeoffs are mixed, you're making an informed choice rather than guessing.

Most buyers who do this comparison are surprised by how much variation exists between lenders quoting the same loan type. Rate headlines rarely tell the whole story. The Loan Estimate does.
