Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation	The interim condensed consolidated financial statements include the accounts of Green Bancorp, Inc. (“Green Bancorp”), together with Green Bank, N.A., its subsidiary bank, (the “Company”). All intercompany transactions and balances have been eliminated.
Basis of Accounting	The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial information. In the opinion of management, the interim statements reflect all adjustments necessary for a fair presentation of the financial position, results of operations and cash flows of the Company on a consolidated basis and all such adjustments are of a normal recurring nature. These financial statements and the accompanying notes should be read in conjunction with the Company’s audited financial statements for the years ended December 31, 2013 and 2012. Operating results for the three and nine months ended September 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014 or any other period. The consolidated financial statements and accompanying notes and other detailed information can be found in the Company’s Registration Statement on Form S-1 filed with the Securities and Exchange Commission and declared effective on August 7, 2014.
Use of Estimates	Use of Estimates—The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of real estate acquired through foreclosure, acquired loans and deposits, deferred tax assets, goodwill, and stock based compensation.

Disclosure of accounting policy regarding (1) the principles it follows in consolidating or combining the separate financial statements, including the principles followed in determining the inclusion or exclusion of subsidiaries or other entities in the consolidated or combined financial statements and (2) its treatment of interests (for example, common stock, a partnership interest or other means of exerting influence) in other entities, for example consolidation or use of the equity or cost methods of accounting. The accounting policy may also address the accounting treatment for intercompany accounts and transactions, noncontrolling interest, and the income statement treatment in consolidation for issuances of stock by a subsidiary.
