Bank Earnings: When Two Correct Calculations Disagree

Open a bank earnings release and resist the urge to pick a winner from the first percentage. In the worked example below, Citi has the wider gap between revenue and expense growth. Bank of America adds more dollars after operating expenses. Both calculations are correct. They answer different questions.

First, decide what you are trying to measure

The practical starting point is a profit bridge: copy matching periods, subtract expenses, and keep going until the result agrees with reported net income. Ratios become more useful once you can explain the dollars underneath them.

This is an accounting reading method, not a forecast or a bank-quality score. It will help you find an omitted line. It cannot tell you which stock offers the best return.

Label the adjustment before doing the comparison

JPMorgan reported EPS of $7.70. Its release attributes $1.27 to a Visa gain and $0.29 to equity-investment gains, leaving $6.14 excluding those significant items. Keep that company-defined adjustment beside the reported figure; do not quietly replace one with the other. JPMorgan earnings release.

An exclusion is not a certificate of recurring earnings. Trading conditions, credit costs and taxes still affect the remainder. The JPMorgan analysis follows that narrower question. Here, we will use unadjusted consolidated income-statement amounts for BAC and Citi, without claiming the two businesses are fully normalized or identical.

Copy the same columns, then subtract

Source evidence: BAC earnings release, printed page 14, published 2026-07-14, reviewed 2026-09-23. Selected original GAAP numerical fields reflowed for readability; not an original-layout screenshot. Q2 2026 versus Q2 2025; USD millions.

The revenue line is already net of interest expense. Do not deduct that expense again. Noninterest expense and provision remain separate deductions. Use the same quarter in both columns, rather than mixing a quarterly amount with a year-to-date total.

At BAC, subtracting the expense increase from the revenue increase leaves $2,671M before the change in provision. Repeating the calculation for Citi leaves $2,460M. These are changes in dollars, not margins, and neither amount is yet the change in net income.

Now ask the percentage question. Divide each bank's revenue increase by its own prior-year revenue; divide the expense increase by its own prior-year expense; subtract the resulting growth rates. The gap is 6.59 percentage points for BAC and 9.60 percentage points for Citi.

Citi leads on the growth-rate gap because that calculation uses different starting bases. BAC leads on added dollars before provisions. There is no contradiction to resolve by choosing a favorite metric. Write down the question first. The BAC revenue guide also explains why income categories and business segments must not be added as if they were independent revenue streams.

Do not stop at pretax profit

Source evidence: Citi financial supplement, printed page 2, published 2026-07-14, reviewed 2026-09-23. Selected original numerical fields reflowed, not an original-layout screenshot. Q2 2026 versus Q2 2025; USD millions. Total provision includes credit losses, benefits and claims.

The following bridge uses changes, not the full expense balances. A positive sign adds to the year-over-year profit increase; a negative sign reduces it. Each subtotal replaces the rows above it rather than adding to them.

Derived reconciliation: current quarter minus the same prior-year quarter, using the source fields above. The final row agrees with each company's net-income change. This bridge does not reconcile earnings available to common shareholders or EPS.

Citi's attribution line is easy to skip. It represents profit belonging to minority owners in consolidated subsidiaries, not another operating expense. Omitting it leaves a result that does not match Citigroup's net income.

EPS needs another reconciliation: earnings available to common shareholders and the applicable weighted-average share count. Dividing this bridge's net income by period-end shares would not reproduce that calculation. Keep the finish line explicit.

A smaller provision can hide a different credit story

Citi's total provision fell $350M, but its realized loan net credit losses rose $170M and its loan provision rose $126M. The total and the loan-only lines cover different things. The Citi credit breakdown follows those components; a favorable total alone does not establish healthier borrowers.

Nor can you rank JPMorgan's 3.34% Card Services net charge-off rate against BAC's 0.47% consolidated ratio. One describes cards; the other covers a broader loan book. Compare a consistently defined portfolio with its own history before making a credit judgment.

The profit bridge also leaves capital needs, business mix and future investment unresolved. A bank can improve short-term conversion while postponing necessary spending. A larger dollar increase may reflect size; a wider growth gap may reflect an easier starting point. Neither settles valuation.

Leave a worksheet for the next filing

The published calendars list JPMorgan and Citi for 2026-10-13 and BAC for 2026-10-14; dates can change. Rebuild the worksheet when the releases arrive. A restatement, an omitted line or a changed definition requires revising the calculation, not defending the previous ranking.

The useful habit is simple: do not stop until the arithmetic reaches the profit line you actually meant to explain.

Sources and calculation notes

Primary releases were rechecked on 2026-09-23. The worked comparison uses Q2 2026 and Q2 2025 consolidated amounts. Growth gaps use unrounded input values and are rounded only at the end. They are not changes in profit margin. This method is not a backtested prediction of earnings or share returns.
