How do I calculate the non-performing assets (NPA) ratio?

Divide a bank's total non-performing assets by its total assets. Non-performing assets include non-performing loans, other real estate owned (OREO), and any other foreclosed assets. The result, expressed as a percentage, shows how much of the bank's balance sheet is tied up in problem assets.

The formula is straightforward:

NPA Ratio = Non-Performing Assets / Total Assets

Non-performing assets (NPAs) are the sum of three components:

Non-performing loans: loans on non-accrual plus loans 90 or more days past due and still accruing

Other real estate owned (OREO): property the bank has acquired through foreclosure or deed-in-lieu of foreclosure

Other foreclosed assets: non-real-estate collateral such as equipment or vehicles that the bank has seized

The result is expressed as a percentage.

Walking Through the Calculation

1. Start with non-performing loans. This is the same figure used in the NPL ratio numerator: loans on non-accrual status plus any loans 90 or more days past due that are still accruing interest.

2. Add OREO. This is real property the bank now owns because a borrower defaulted. It shows up on the balance sheet under "other assets" or sometimes as its own line item.

3. Add other foreclosed assets if the bank carries any. Not every bank has these, but some hold repossessed equipment, vehicles, or other non-real-estate collateral.

4. The sum of those three categories is total non-performing assets.

5. Find total assets on the balance sheet.

6. Divide non-performing assets by total assets.

Worked Example

A bank reports $53 million in non-performing loans, $12 million in OREO, and $2 million in other foreclosed assets. Total assets are $6.8 billion.

Non-performing assets = $53M + $12M + $2M = $67 million NPA ratio = $67M / $6.8B = 0.99%

That result means just under 1% of this bank's total assets are problem assets.

What the Result Tells You

Most well-run banks maintain NPA ratios below 1%. Ratios between 1% and 2% typically warrant closer investigation into which loan categories are generating the problems and whether the trend is improving or deteriorating. Above 2%, the bank's asset quality is a genuine concern, and investors should look carefully at capital levels, reserve adequacy, and management's workout strategy.

For historical context, many banks saw NPA ratios climb above 5% during 2008-2010, and some exceeded 10%. Those extreme levels often preceded dividend cuts, capital raises, or regulatory action. While such episodes are unusual, they illustrate how rapidly NPAs can accumulate when credit conditions deteriorate across multiple loan categories simultaneously.

NPA Ratio vs. NPL Ratio

Confusing these two ratios is one of the most common mistakes in bank analysis. They're related, but they measure different things.

The NPL ratio divides non-performing loans by total loans. The NPA ratio uses a broader numerator (adding OREO and other foreclosed assets to non-performing loans) and a larger denominator (total assets instead of total loans). Because of these differences, the two ratios capture different stages of credit deterioration.

The NPL ratio focuses on loans that are delinquent or no longer accruing interest. The NPA ratio captures the full lifecycle of credit problems, including situations where the bank has already foreclosed and taken possession of collateral. A bank that aggressively forecloses on delinquent borrowers might show an improving NPL ratio while its NPA ratio holds steady or even rises, because problem loans are being converted to OREO rather than truly resolved.

In percentage terms, the NPA ratio will almost always print lower than the NPL ratio for the same bank, since total assets is a much larger number than total loans. But an analyst who only tracks NPLs could miss a bank that is quietly accumulating foreclosed properties.

The Texas Ratio Connection

The Texas Ratio shares the same numerator as the NPA ratio: total non-performing assets. Instead of dividing by total assets, the Texas Ratio divides NPAs by the sum of tangible common equity and loan loss reserves. This reframes the question from "what share of assets are problematic" to "can the bank's capital and reserves absorb its problem assets?"

A Texas Ratio above 100% means problem assets exceed the bank's combined equity cushion and loss reserves. Historically, this has been a reliable distress signal. If you've already calculated total NPAs for the NPA ratio, the Texas Ratio requires just two additional data points from the balance sheet.

How OREO Affects Banks Beyond the Ratio

When a bank forecloses on a property, the loan leaves the loan portfolio and the property enters the balance sheet as OREO. The initial carrying value is the lower of the outstanding loan balance or fair market value minus estimated selling costs. If fair value falls below the loan balance, the bank records a charge-off on the difference at the time of transfer.

OREO values don't sit still after that initial recording. Banks must periodically reassess fair values and record additional write-downs if market conditions have worsened. On top of valuation adjustments, holding OREO generates real ongoing costs: property taxes, insurance, maintenance, and sometimes legal fees. These expenses flow through non-interest expense and reduce profitability every quarter the property sits on the books.

A rising OREO balance creates a compounding problem. The asset itself represents a credit failure, and the carrying costs erode earnings until the bank can find a buyer.

What Moves the NPA Ratio Over Time

The NPA ratio reflects the evolving health of a bank's loan book and its approach to handling problem credits. Several forces push the ratio in different directions.

New loan defaults add to NPAs. As performing loans slip into non-accrual or past-due status, the numerator grows. During economic downturns, this flow accelerates across many loan categories at once.

Foreclosures convert NPLs to OREO. This doesn't change total NPAs (the loan leaves, the property enters), but it does signal a progression in severity. Active OREO growth indicates that workout efforts or loan modifications haven't succeeded.

Charge-offs and asset sales reduce NPAs. When a bank writes off a loan entirely or sells a foreclosed property, the asset leaves the NPA total. Banks sometimes sell packages of non-performing assets to specialty investors at a discount to accelerate the cleanup.

Loan portfolio growth affects the denominator indirectly. If total assets grow faster than NPAs, the ratio improves even without any change in the absolute level of problem assets. This is worth watching during periods of aggressive lending.

Differences Across Bank Types

Community banks with concentrated loan portfolios can see dramatic NPA ratio swings from a single borrower relationship going bad. A $500 million community bank heavily exposed to commercial real estate might see its NPA ratio jump from 0.5% to 3% if one large development project fails and generates $10-15 million in foreclosed property.

Larger regional and national banks carry more diversified loan books, so individual credit events move the needle less. Their NPA ratios tend to be more stable from quarter to quarter, though during systemic downturns the absolute dollar volumes can be enormous.

Banks with large consumer and credit card portfolios tend to charge off problem loans quickly rather than letting them linger as NPAs. Their NPA ratios can look artificially low compared to commercial lenders, where extended workout negotiations and loan modifications keep problem credits on the books longer before resolution.

Where to Find the Data

The quickest source for a complete NPA figure is usually the bank's quarterly earnings release. Most banks include a non-performing asset summary table that breaks out NPLs, OREO, and other foreclosed assets separately.

For more detailed information, the credit quality disclosures in 10-K and 10-Q filings provide non-performing loan data by category, and OREO details appear on the balance sheet or in the footnotes. Call report data filed with the FFIEC offers standardized NPA figures that allow direct comparison across institutions.

Common Calculation Mistakes

Using total loans as the denominator instead of total assets. That produces a different ratio entirely. The NPA ratio uses total assets deliberately, framing problem assets against the full balance sheet.

Omitting OREO or other foreclosed assets from the numerator. Including only non-performing loans gives you the NPL ratio, not the NPA ratio. The distinction matters because the whole purpose of the NPA ratio is to capture credit problems that have progressed beyond delinquent loans.

Double-counting items across the NPL and OREO categories. Once a bank forecloses, the loan is removed from the loan portfolio and the property becomes OREO. Including the same credit problem in both categories overstates the numerator.

Comparing NPA ratios across banks without considering differences in charge-off speed. A bank that writes off problem loans quickly will report a lower NPA ratio than one that holds them through an extended workout, even if underlying credit quality is similar.
