TTM Calculator - Trailing Twelve Months

Trailing twelve-month, or TTM, revenue is the sum of the last four reported quarters. Investors prefer TTM to the last fiscal year when a business is growing or shrinking quickly, because a stale 10-K can be three quarters out of date. The TTM calculator adds the four quarterly revenue inputs you provide. It does not mix earnings or EBITDA into the displayed total; those are separate TTM series you would sum on their own. Quarters of $10,000,000, $12,000,000, $11,000,000, and $15,000,000 produce TTM revenue of $48,000,000. Four flat quarters of $25 each (in millions, or any other unit) produce 100 in the same unit. An $8, $9, $10, and $12 sequence produces 39. Keep the unit consistent. Do not add a quarter in thousands to a quarter in millions. Use TTM revenue for valuation multiples such as EV/sales, for run-rate checks, and for covenant tests that refer to the last twelve months rather than the fiscal year. For a calendar reporter that just printed Q3, TTM is Q4 of last year plus Q1, Q2, and Q3 of this year. Label the four boxes in chronological order so a reader can see the trend inside the sum. TTM still includes seasonality. A retailer with a huge Q4 will look stronger just after Christmas and weaker in the following spring even if the underlying trend is unchanged. Restatements, discontinued operations, and mid-year acquisitions also break comparability. The calculator does not annualize a stub period and does not currency-translate foreign subsidiaries. Recalculate when a new 10-Q arrives, and document which four quarters went into the total whenever you quote a TTM multiple. When you quote TTM revenue next to a price or enterprise value, state the as-of date of the newest quarter so readers can rebuild the sum. Do not splice a management “run-rate” figure into one of the four boxes unless that figure is actual recognized revenue. Used with care, trailing twelve-month revenue is a cleaner sales snapshot than a dated fiscal year, but it remains only an arithmetic total of four reported quarters.
