Trailing twelve months figures give the most up-to-date view of a full year’s performance without waiting for the annual report, and remove seasonal effects of looking at one quarter alone.
How to use the TTM Calculator – Trailing Twelve Months
- Last reported quarter
- One quarter before
- Two quarters before
- Three quarters before
- Shares outstanding
- Share price
- Dividends per share in the last 12 months
Results update as you type, and every field accepts the units shown in its menu.
How it works
Enter the figure for each of the last four quarters (most recent first), and optionally shares, share price and dividends.
Tips
- Use the nominal annual rate and pick the compounding frequency your bank or broker states.
- Small differences in return or fees compound into large differences over decades.
- Run the calculation with a cautious, a central and an optimistic return to see the range of outcomes.
- Past returns do not guarantee future returns – nothing here is investment advice.
Common mistakes to avoid
- Comparing an APR with an APY or effective rate.
- Ignoring inflation, taxes and fees when judging a real return.
- Entering a percentage as a decimal (5 instead of 0.05 is correct here).

What each result means
- Trailing twelve months value = [Last reported quarter] + [One quarter before] + [Two quarters before] + [Three quarters before]
- TTM per share = [Trailing twelve months value]÷[Shares outstanding]
- TTM P/E (if the figure is net income) = [Share price]÷[TTM per share]
- TTM dividend yield = [Dividends per share in the last 12 months]÷[Share price]×100
- Latest quarter growth vs a year earlier (annualized run-rate) = ([Last reported quarter]×4÷[Trailing twelve months value] – 1)×100
Example values
How the main result changes when Last reported quarter changes and everything else stays at the example values above:
| Last reported quarter | Trailing twelve months value |
|---|---|
| 1,300,000 | 8,200,000 |
| 1,950,000 | 8,850,000 |
| 2,600,000 | 9,500,000 |

| 3,900,000 | 10,800,000 |
| 5,200,000 | 12,100,000 |
Formula
TTM = sum of the last four quartersTTM EPS = TTM net income ÷ shares; TTM P/E = price ÷ TTM EPSTTM dividend yield = TTM dividends per share ÷ priceWorked example
Inputs — Last reported quarter: $2,600,000; One quarter before: $2,400,000; Two quarters before: $2,300,000; Three quarters before: $2,200,000; Shares outstanding: 5,000,000; Share price: $40; Dividends per share in the last 12 months: $0.8.
Results — Trailing twelve months value = $9,500,000.00; TTM per share = $1.90; TTM P/E (if the figure is net income) = 21.05; TTM dividend yield = 2 %; Latest quarter growth vs a year earlier (annualized run-rate) = 9.47 %.
