What has been the last twelve months?
The term last twelve months refers to the most recent twelve consecutive months of a company’s financial performance. It is also known as trailing twelve months.

LTM meaning in finance
In finance , LTM is very important because financial markets move quickly. Annual reports can become outdated within a few months especially in industries that experience rapid growth or changing market conditions. The LTM approach helps you measure recent business performance, compare companies more accurately, build realistic valuation models and track growth trends. This makes LTM as one of the most commonly used metrics and financial modelling and investment analysis.
Why does the last twelve months matter?
Before diving into formulas and calculations it’s important to understand why LTM is so widely used. Your company’s annual report might not reflect its latest business conditions. Revenue might have increased sharply in recent quarters or profits might have declined due to economic changes. Using outdated annual data can lead to inaccurate analysis. LTM solves the problem by combining the latest available quarterly financial information with historical annual statements.

- FY2025 Revenue = ₹500 crore
- Q1 2026 Revenue = ₹140 crore
