Introduction
When researching a company before investing, you’ve probably noticed different earnings metrics on financial websites. Two of the most common are EPS TTM and EPS Annual. While both measure a company’s profitability, they don’t represent the same time period or provide the same insights.
Understanding EPS TTM vs. EPS Annual is essential because many investors mistakenly compare these figures without knowing what they actually represent. This can lead to incorrect valuation, unrealistic growth expectations, and poor investment decisions.
Whether you’re a beginner or an experienced investor, knowing when to use TTM earnings and annual earnings can help you evaluate companies more accurately.
What is EPS?
EPS stands for Earnings Per Share.
It represents the amount of profit a company earns for each outstanding share of its stock.
Formula
EPS = (Net Profit – Preferred Dividends) ÷ Average Outstanding Shares
For example:
- Net Profit = ₹500 Crore
- Shares Outstanding = 100 Crore
EPS = ₹500 ÷ 100
EPS = ₹5
This means the company generated ₹5 profit for every share.
A higher EPS generally indicates stronger profitability.
What is EPS TTM?
TTM stands for Trailing Twelve Months.
EPS TTM represents the company’s earnings per share over the most recent four quarters.
Instead of waiting for the financial year to end, TTM always reflects the latest available earnings.
For example:
| Quarter | EPS |
| Q2 2025 | ₹3 |
| Q3 2025 | ₹4 |
| Q4 2025 | ₹5 |
| Q1 2026 | ₹6 |
EPS TTM
= 3 + 4 + 5 + 6
= ₹18
As every new quarterly result is announced, the oldest quarter drops out and the newest quarter is added.
This makes EPS TTM a continuously updated profitability measure.
What is annual EPS?
Annual EPS represents earnings generated during a company’s completed financial year.
For example:
Financial Year 2025
Quarterly EPS
- Q1 = ₹2
- Q2 = ₹3
- Q3 = ₹3
- Q4 = ₹4
Annual EPS
= ₹12
Unlike TTM, annual EPS remains unchanged until the company completes another financial year.

| Feature | EPS TTM | EPS Annual |
| Time Period | Latest 12 months | Completed financial year |
| Updates | Every quarter | Once a year |
| Shows Latest Performance | Yes | No |
| Useful During Year | Yes | Limited |
| Reflects Recent Growth | Yes | No |
| Better for Current Valuation | Yes | Less accurate |
| Stability | Moderate | High |
| Best For | Active investors | Historical comparison |
Why EPS TTM Matters More Today
Stock prices move daily.
Companies release quarterly results every three months.
If investors only relied on annual EPS, they could be using financial information that’s almost a year old.
EPS TTM solves this problem by including the latest quarterly earnings.
For example:
Annual EPS (FY2025)
₹20
Quarter 1 FY2026
EPS = ₹8
Quarter 2 FY2026
EPS = ₹9
Quarter 3 FY2026
EPS = ₹10
Now the company’s profitability has improved significantly.
TTM reflects this improvement much earlier than annual EPS.
Why Annual EPS is Still Important
Although TTM is more current, annual EPS is still valuable because it:
- Shows yearly profitability
- Helps compare multiple financial years
- Removes short-term fluctuations
- Makes long-term trend analysis easier
- Supports historical financial analysis
Investors often examine annual EPS over the last 5–10 years to assess consistency.
Example: Understanding EPS TTM vs EPS Annual
Imagine Company ABC.
Financial Year 2025
| Quarter | EPS |
| Q1 | ₹4 |
| Q2 | ₹5 |
| Q3 | ₹5 |
| Q4 | ₹6 |
Annual EPS
₹20
Now in FY2026:
| Quarter | EPS |
| Q1 | ₹8 |
| Q2 | ₹9 |
Current EPS TTM
Q3 FY25 = ₹5
Q4 FY25 = ₹6
Q1 FY26 = ₹8
Q2 FY26 = ₹9
TTM EPS
= 5 + 6 + 8 + 9
= ₹28
Notice something important.
Annual EPS still shows ₹20.
TTM already reflects the improved profitability at ₹28.
That’s why investors usually focus on TTM while valuing stocks.
Which metric is used for the PE ratio?
One of the biggest reasons investors compare EPS TTM vs. EPS Annual is because of the price-to-earnings (P/E) ratio.
Formula:
P/E = Current Share Price ÷ EPS
Suppose
Share Price = ₹560
Annual EPS = ₹20
P/E = 28
Now TTM EPS
₹28
Updated P/E
₹560 ÷ ₹28
= 20
Notice how the valuation changes dramatically.
Using outdated earnings can make a stock appear more expensive than it actually is.
Benefits of EPS TTM
Most Current Financial Picture
TTM reflects the latest available company performance.
Better for Fast-Growing Companies
Companies growing rapidly may have significantly higher earnings than last year’s annual EPS.
Useful for Quarterly Analysis
Investors don’t need to wait for year-end reports.
Better Valuation
Most professional investors calculate valuation using TTM earnings.
Detects Growth Earlier
TTM quickly captures improving business performance.
Benefits of Annual EPS
Stable Measurement
Annual data is less affected by seasonal changes.
Easier Historical Comparison
Comparing Annual EPS over several years helps identify long-term trends.
Useful for Conservative Investors
Long-term investors often prefer reviewing yearly performance before making investment decisions.
Helpful for Dividend Analysis
Companies usually declare dividends based on annual earnings.
Limitations of EPS TTM
Although useful, TTM has certain drawbacks.
Seasonal Businesses
Retail companies often earn higher profits during festive seasons.
TTM may temporarily overstate profitability.
One-Time Income
If a company sells an asset and records exceptional profit, TTM EPS may appear artificially high.
Quarterly Volatility
Unexpected gains or losses can significantly impact TTM.
Limitations of Annual EPS
Annual EPS also has disadvantages.
- May become outdated quickly
- Doesn’t capture recent business improvements
- Less useful during the current financial year
- May underestimate fast-growing companies
- Can overestimate declining businesses
When Should Investors Use EPS TTM?
TTM is ideal when:
- Buying or selling stocks
- Calculating current P/E Ratio
- Comparing competitors
- Tracking quarterly growth
- Evaluating recent business performance
When Should Investors Use Annual EPS?
Annual EPS is better when:
- Studying long-term financial history
- Comparing profitability over multiple years
- Evaluating management consistency
- Performing historical research
The lower TTM indicates earnings have weakened recently.
This can be an early warning sign.
This signals improving profitability.
Why Analysts Prefer EPS TTM
Professional analysts usually rely more on TTM because it:
- Reflects recent earnings
- Updates every quarter
- Improves valuation accuracy
- Captures changing business trends
- Helps compare companies fairly
That’s why many financial platforms display TTM EPS as the default metric.
How to Interpret EPS Correctly
Never evaluate EPS in isolation.
Combine it with:
- Revenue Growth
- Net Profit Margin
- Return on Equity (ROE)
- Debt-to-Equity Ratio
- Free Cash Flow
- P/E Ratio
- PEG Ratio
- Return on Capital Employed (ROCE)
A company with rising EPS but increasing debt may not be as attractive as it first appears.
Common Mistakes Investors Make
Comparing Different Time Periods
Don’t compare TTM EPS of one company with annual EPS of another.
Always compare the same metric.
Ignoring Quarterly Results
Annual EPS may miss significant recent changes.
Looking Only at EPS
EPS alone doesn’t reveal the complete financial picture.
Ignoring Share Dilution
If the company issues additional shares, EPS may decline even when profits increase.
Ignoring Exceptional Items
One-time gains can temporarily inflate EPS.
Which is better: EPS TTM or annual EPS?
There isn’t a single “better” metric. Each serves a different purpose.
Choose EPS TTM when you need the latest view of a company’s earnings, especially for valuation, comparing peers, or making near-term investment decisions.
Choose annual EPS when analyzing long-term performance, consistency, and historical growth over several years.
Smart investors don’t pick one over the other—they use both together. Comparing Annual EPS with TTM EPS can reveal whether a company’s earnings are improving, stable, or declining, helping you make more informed investment decisions.
Best Practices for Stock Investors
- Compare TTM EPS with annual EPS to identify earnings trends.
- Review at least five years of annual EPS before investing.
- Use TTM EPS when calculating the current P/E ratio.
- Analyze quarterly earnings reports alongside TTM data.
- Exclude one-time gains or losses when possible to understand core profitability.
- Always evaluate EPS alongside other financial metrics such as revenue growth, ROE, cash flow, and debt levels.
Final Thoughts
Understanding EPS TTM vs. EPS annual is essential for anyone serious about stock investing. While both metrics measure earnings per share, they provide different perspectives on a company’s financial performance.
EPS TTM offers the most recent snapshot by combining the latest four quarters, making it valuable for current valuation and investment decisions. Annual EPS, on the other hand, provides a stable historical view that’s useful for tracking long-term performance and consistency.
Instead of relying on just one metric, experienced investors use both. Annual EPS helps identify long-term trends, while TTM EPS highlights recent momentum. Together, they provide a more complete picture of a company’s earnings quality and financial health.
Before investing in any stock, always look beyond EPS. Consider growth, cash flow, profitability, debt, management quality, industry outlook, and overall business fundamentals. A balanced approach leads to better-informed investment decisions and reduces the risk of being misled by a single financial metric.
FAQs
What is the main difference between EPS TTM and EPS annual?
The main difference is the time period they cover. EPS TTM reflects earnings from the latest 12 months (last four quarters), while annual EPS represents earnings from a completed financial year.
Which is better for calculating the P/E ratio?
Most investors and analysts prefer using EPS TTM because it reflects the company’s latest earnings and provides a more current valuation.
Why does EPS TTM change every quarter?
TTM uses a rolling 12-month period. Each new quarterly result replaces the oldest quarter, keeping the metric updated.
Can EPS TTM be higher than annual EPS?
Yes. If a company’s earnings are improving, the latest four quarters may produce a higher TTM EPS than the previous financial year’s annual EPS.
Should long-term investors ignore annual EPS?
No. Annual EPS remains important for evaluating historical performance, earnings consistency, and long-term growth trends.
Is a higher EPS always a good sign?
Not necessarily. Investors should also assess revenue growth, debt levels, cash flow, margins, and whether the increase in EPS is driven by sustainable business performance rather than one-time events.
