TTM Calculator — Trailing Twelve Months

Formula

How this is calculated

Financial statements are reported quarterly in most markets, creating a lag between the end of a fiscal year and the availability of updated annual figures. TTM (also called LTM — last twelve months) bridges that gap by adding the four most recent consecutive quarters regardless of where they fall in the fiscal calendar. The result is an annualised, current number that incorporates the latest earnings or revenue trends without waiting for the next annual report.

For valuation ratios the TTM figure is preferred over stale fiscal-year data. A TTM P/E = Share Price ÷ TTM EPS reflects the price the market is paying relative to the most recent trailing earnings power. A TTM P/S = Market Cap ÷ TTM Revenue is used for pre-earnings or high-growth companies where earnings are less meaningful. Because TTM is backward-looking it can miss inflection points (a recent acquisition or divestiture, a seasonal quarter that distorts the run-rate), so forward (next-twelve-months, NTM) estimates are often used alongside it.

This calculator takes the four quarterly inputs as entered (positive or negative — losses are valid), sums them to produce the TTM, and optionally computes year-on-year growth versus a prior-period total and simple valuation multiples when a share price is provided. Units are not prescribed — enter millions, billions, per-share amounts, or any consistent unit and the ratio calculations remain valid.
