What is trailing twelve months (TTM)?

Trailing twelve months rolling financial data from the most recent four quarters or adjusted interim periods. Analysts use TTM to smooth seasonality and evaluate the latest full year of performance without waiting for fiscal year-end filings.

After calculating TTM earnings, convert to valuation ratios with the earnings per share calculator or the price-to-earnings calculator.

TTM calculation methods

Quarterly summation

TTM=Q1+Q2+Q3+Q4\text{TTM} = Q1 + Q2 + Q3 + Q4

Add the four most recent consecutive quarters. Example: $50,000 + $55,000 + $60,000 + $65,000 = $230,000 TTM revenue or net income.

Interim period adjustment

TTM=FY+Current Interim−Prior Interim\text{TTM} = \text{FY} + \text{Current Interim} - \text{Prior Interim}

Start with the last full fiscal year, add the current year-to-date interim figure, and subtract the same interim period from the prior year. This updates TTM when only semi-annual or year-to-date reports are available.

Optional valuation ratios

TTM EPS equals TTM net income divided by weighted shares outstanding. TTM P/E equals share price divided by TTM EPS when earnings are positive.

Frequently asked questions

What metrics can I run on a TTM basis?
Revenue, net income, EBITDA, free cash flow, and other income statement items are commonly annualized with TTM. Balance sheet items are point-in-time and are not summed across quarters.
Which quarters should I include?
Use the four most recent reported quarters in chronological order. Do not skip a quarter or mix fiscal and calendar periods unless you adjust consistently.
When should I use the interim adjustment method?
Use it when the company reports year-to-date or half-year results and you want a rolling twelve-month figure before four fresh quarters are available.
Why is P/E blank for negative TTM earnings?
Price-to-earnings is not meaningful when EPS is zero or negative. The calculator shows a placeholder instead of a misleading ratio.
Are results stored on your servers?
No. All math runs in your browser. Nothing is sent to the server.
