TTM Trailing Twelve Months Calculator - 4-Quarter Rolling Sum

A TTM trailing twelve months calculator adds the four most recent quarterly values of any income statement or cash flow statement metric into a single rolling total, so you can review a company's last twelve months of performance even when the fiscal year is not complete. Use it when you are screening a public company between annual reports, updating a valuation multiple after a new earnings release, or comparing two companies on a recent twelve-month basis.

• • Mid-year screen: Build a recent twelve-month revenue, EPS, or EBITDA total without waiting for the next annual report.
• • Valuation update: Pair the rolling total with a current share price or enterprise value to update TTM P/E or EV to TTM EBITDA.
• • Peer comparison: Compare two companies using the same four-quarter window so fiscal year-end timing does not skew the analysis.
• • Yield review: Combine TTM dividends per share with the current share price to estimate the trailing dividend yield.

TTM is useful because most public companies report on a calendar that does not line up with the date you are doing analysis. Two companies with different fiscal year-ends can be compared on a recent twelve-month basis even when the most recent annual report for one is older.

The TTM trailing twelve months calculator is also a quick way to refresh a valuation multiple after a new earnings release. Update the four most recent quarterly lines and recompute TTM revenue, TTM EBITDA, TTM EPS, or TTM free cash flow without rebuilding the forecast.

Keep TTM in its proper role. It is a rolling subtotal, not a forecast or a quality score. Use TTM to ask better questions about the next quarter and the next full year before acting on the number.

When the four quarters are revenue lines, the revenue calculator is a useful companion for reviewing the most recent twelve-month sales total.

The calculator adds the four most recent reported quarterly values for the metric you choose. If you also enter a share price, enterprise value, or TTM dividend per share, the page adds the matching valuation ratio.

• Q(t): Most recently reported quarter of revenue, EPS, EBITDA, free cash flow, or the metric you choose.
• Q(t-1): The quarter ending one reporting period before Q(t).
• Q(t-2): The quarter ending two reporting periods before Q(t).
• Q(t-3): The quarter ending three reporting periods before Q(t); the oldest of the four.
• Share price: Current share price used to compute TTM P/E when the quarters are per-share values.
• Enterprise value: Current enterprise value used to compute EV to TTM EBITDA when the quarters are EBITDA.
• TTM dividend per share: Sum of dividends per share across the last four quarters, paired with share price for TTM dividend yield.

Once the four quarters are entered, the calculator returns the rolling TTM total. TTM P/E is share price divided by the rolling total when both are positive. EV to TTM EBITDA is enterprise value divided by the rolling total. TTM dividend yield is TTM dividend per share divided by share price.

Leave the valuation inputs blank to use the page as a general rolling-sum tool for any metric reported quarterly, including revenue, EBITDA, free cash flow, and operating cash flow.

According to Investopedia, trailing twelve months (TTM) is the term for the past 12 months of a company's financial performance, commonly used to evaluate recent financial data without waiting for the annual report.

If the four quarters are EBITDA values, the EBITDA calculator can confirm the single-period EBITDA add-backs before you sum them into a trailing twelve-month total.

These four ideas keep the rolling number honest and help decide when to use TTM versus the latest annual report.

TTM and LTM are used interchangeably in most finance and equity research materials. The terms refer to the same rolling twelve-month total.

A TTM total is a subtotal, not a substitute for an annual report. The annual report includes the auditor opinion, footnote detail, and segment data that a TTM subtotal does not capture. Use TTM to refresh analysis between annual reports.

To translate per-share quarters into TTM EPS before computing TTM P/E, the EPS calculator isolates the single-period basic and diluted EPS values.

Pick the metric first, then enter the four most recent quarterly values in the order shown. Add valuation inputs only for the ratios you want to compute.

1. 1 Pick the metric type: Choose revenue, EPS, EBITDA, free cash flow, operating income, or a custom metric so the rolling total is easier to interpret.
2. 2 Enter the four most recent quarters: Type the most recent quarter first, then the quarter before it, two quarters back, and three quarters back, all in the same units.
3. 3 Confirm the units match: Use the same units across all four quarters. Mixing thousands and millions, or basic and diluted EPS, will distort the rolling total.
4. 4 Add share price if you need TTM P/E: Enter the current share price only when the four quarters are per-share values such as EPS.
5. 5 Add enterprise value for EV to TTM EBITDA: Enter enterprise value only when the four quarters are EBITDA values.
6. 6 Read the review note: Use the review note to spot missing valuation inputs or a TTM total that is zero or negative.

For a US large-cap, take the latest four 10-Q and 10-K revenue lines from the SEC's EDGAR system, enter them in reverse chronological order, and read the TTM revenue total.

When you also enter a current share price, the price to earnings calculator confirms the trailing P/E you compute from the rolling twelve-month EPS total.

The main value is a transparent rolling total that updates the moment a new quarter is reported.

• • Faster mid-year review: Build a recent twelve-month total without waiting for the next annual report.
• • Cleaner valuation updates: Refresh TTM P/E and EV to TTM EBITDA after each earnings release.
• • Comparable peer analysis: Compare two companies on the same recent twelve-month basis, even when their fiscal year-ends differ.
• • Yield context: Pair TTM dividends per share with the current share price to estimate the trailing dividend yield.
• • Audit-friendly math: Show each quarter separately so a reviewer can match every line in the rolling total back to the original filing.

The TTM trailing twelve months calculator is also a teaching tool. New analysts can see which four reporting periods were combined, and experienced analysts can confirm a colleague's TTM total without digging through the model.

In a research note, the TTM figure pairs naturally with other multiples. TTM revenue feeds a price-to-sales ratio, TTM EBITDA feeds EV to TTM EBITDA, and TTM EPS feeds TTM P/E.

To turn a TTM EBITDA total into a valuation multiple, the EBITDA multiple calculator divides enterprise value by trailing twelve months EBITDA once the rolling total is known.

TTM results change with reporting calendar, one-time items, and how the company defines the metric you are summing.

• • TTM is a rolling subtotal, not a GAAP measure. The SEC requires non-GAAP measures such as TTM EBITDA to be reconciled to the most directly comparable GAAP measure in any public filing or earnings release that highlights them.
• • TTM ratios are not meaningful when the rolling total is zero or negative. A company with a TTM loss cannot have a meaningful TTM P/E or EV to TTM EBITDA multiple, and the calculator will skip those outputs.
• • TTM does not include the auditor opinion, footnote detail, or segment data that a full annual report provides. Use TTM for fast review and the annual report for final decisions.

When you cite a TTM total in a public-facing note, prefer the company's own reconciliation table over a headline number. Public-company filings usually show how management builds the rolling twelve-month subtotal.

Industry context matters. Software, manufacturing, retail, and utilities can have different seasonality, so a four-quarter window can hide a slow quarter. Compare the TTM total to the latest annual figure before drawing conclusions.

According to SEC Division of Corporation Finance, non-GAAP measures such as TTM EBITDA and other rolling twelve-month aggregations must be reconciled to the most directly comparable GAAP measure so that investors can see how the rolling period was constructed.

According to Corporate Finance Institute, the EV/EBITDA multiple compares enterprise value to earnings before interest, taxes, depreciation, and amortization, and the EBITDA figure is typically a rolling sum of the last four reported quarters.
