IBM System z Software Pricing

Monthly License Charge (MLC) Metrics

Monthly License Charge (MLC) metrics are those where a recurring charge applies each month. This charge includes the right to use the product, and also access to IBM product support during the support period. IBM offers a variety of MLC pricing metrics to meet the diverse needs of our mainframe customers.

An IBM pricing metric establishes both the prices and the applicable terms and conditions for IBM software products. Select an MLC pricing metric, based on your goals and/or your environment. The selected metric will be used to price MLC products, such as z/OS, z/TPF, z/VSE, middleware, compilers and selected systems management tools and utilities.
