Trailing twelve months calculator.
See a complete twelve-month window ending at your latest entered month. Missing months remain visible and block a full trailing-year result.
Use the free tool ↓A PRACTICAL STARTING POINT
A full year, without annualising a partial one.
The tool selects the latest recorded month and the eleven calendar months before it. It calculates revenue, expenses and their difference only if all twelve months are present. For example, twelve monthly revenue entries of 1,000 and expense entries of 400 produce revenue 12,000, expenses 4,800 and a difference of 7,200. Eleven entries do not become an estimate for twelve.
HOW TO USE THIS TOOL
- Choose one currency and consistent accounting basis in Business profile.
- Enter twelve consecutive monthly records and their source notes below.
- Review the trailing-year window above the table. Correct any missing month before relying on the total.
A trailing-period arithmetic summary is not a formal accounting statement, earnings adjustment or future forecast. Method: addition of a complete, explicitly selected set of user-entered calendar months. No external financial dataset is involved.
