TTM Calculator – Trailing Twelve Months
Free online TTM calculator to estimate trailing twelve months values from the latest four quarterly figures. This calculator is useful for investors, finance students, analysts, business owners, and anyone reviewing rolling annual performance without waiting for a full fiscal year to end. TTM stands for trailing twelve months. It is a common finance measure used to convert the latest four quarters of revenue, earnings, EBITDA, cash flow, or another metric into a current rolling annual total. That makes it more timely than relying only on the last completed annual report.
This calculator uses four main inputs. Most recent quarter means the latest quarterly value available. Two quarters ago, three quarters ago, and four quarters ago complete the last four reported quarters. Once those values are entered, the calculator shows trailing twelve months total, average quarterly value, average monthly value, and latest quarter share of TTM. These outputs help you see the annualized rolling total and also whether the latest quarter is becoming a larger or smaller part of overall performance.
The formula of TTM
TTM total = Quarter 1 + Quarter 2 + Quarter 3 + Quarter 4
Average quarterly value = TTM total / 4
Average monthly value = TTM total / 12
Latest quarter share of TTM = Most recent quarter / TTM total
Here the most recent quarter means the latest reported quarter, the earlier quarters mean the three quarters before it, TTM total means the rolling twelve-month total from the last four quarters combined, average quarterly value means the average quarter over that period, average monthly value means the average month implied by the TTM figure, and latest quarter share of TTM means how much of the rolling annual total came from the latest quarter alone.
Solved Example
Example 1: Find the TTM result if the last four quarters are $320,000, $300,000, $290,000, and $280,000.
Solve: TTM total = 320000 + 300000 + 290000 + 280000 = $1,190,000
Average quarterly value = 1190000 / 4 = $297,500
Average monthly value = 1190000 / 12 = $99,166.67
Latest quarter share of TTM = 320000 / 1190000 = 26.8908%
Example 2: Find the result if the last four quarters are $150,000, $145,000, $140,000, and $135,000.
Solve: TTM total = $570,000
Average quarterly value = $142,500
Average monthly value = $47,500.00
Latest quarter share of TTM = 150000 / 570000 = 26.3158%
Example 3: Find the result if the last four quarters are $90,000, $100,000, $110,000, and $120,000.
Solve: TTM total = $420,000
Average quarterly value = $105,000
Average monthly value = $35,000.00
Latest quarter share of TTM = 90000 / 420000 = 21.4286%

How to use this TTM calculator
Enter the most recent quarter in the proper input field. After that, enter the values from the previous three quarters. Then click the calculate button. The calculator will show trailing twelve months total, average quarterly value, average monthly value, and latest quarter share of TTM in the result box.
This calculator is especially useful when annual reports are outdated and the latest quarter needs to be included in analysis. TTM figures help investors and analysts compare companies on a more current basis, especially when looking at revenue, earnings, margins, cash flow, or operating metrics. Because it uses the most recent four quarters, TTM often gives a better current snapshot than the last full fiscal year.
When using the result, remember that TTM is a rolling measure rather than a seasonal adjustment. A business with strong seasonality may still need extra context when quarters vary widely. Even so, TTM remains one of the most practical ways to convert quarterly data into a current annual view. This calculator gives a fast way to turn the latest four quarters into a usable rolling-twelve-months metric for analysis and comparison.
