Compensation Related Costs [Abstract]
Employees' Profit Sharing and Savings Plan	Note 5 - Employees' Profit Sharing and Savings Plan: Substantially all employees of the Company and its subsidiaries are members of the Value Line, Inc. Profit Sharing and Savings Plan (the "Plan"). In general, this is a qualified, contributory plan which provides for a discretionary annual Company contribution which is determined by a formula based on the salaries of eligible employees and the amount of consolidated net operating income as defined in the Plan. For the nine months ended January 31, 2016 and January 31, 2015, the estimated profit sharing plan contributions, which are included as expenses in salaries and employee benefits in the Consolidated Condensed Statements of Income, were $322,000 and $300,000, respectively.

- Definition

The entire disclosure for compensation costs, including compensated absences accruals, compensated absences liability, deferred compensation arrangements and income statement compensation items. Deferred compensation arrangements may include a description of an arrangement with an individual employee, which is generally an employment contract between the entity and a selected officer or key employee containing a promise by the employer to pay certain amounts at designated future dates, usually including a period after retirement, upon compliance with stipulated requirements. This type of arrangement is distinguished from broader based employee benefit plans as it is usually tailored to the employee. Disclosure also typically includes the amount of related compensation expense recognized during the reporting period, the number of shares (units) issued during the period under such arrangements, and the carrying amount as of the balance sheet date of the related liability.
