ACL Calculator is a hosted solution that allows a client to perform a detailed forecasted allowance calculation effortlessly.

We know that the time, effort, and cost for implementing this standard will be an ongoing process that requires more complex and controlled systems. Our ACL Calculator’s two platforms address current accounting standard requirements and the impending CECL standard.

Leverage the Incurred Loss Model to transition to CECL and process concurrently to seamlessly evolve your allowance modeling and methodology.
