Accuracy Notes and Limitations

All projections assume constant rates. Consult a certified financial planner (CFP) for major decisions. The accuracy of any calculator is limited by the quality of the inputs provided. Double-check your units before entering values — unit errors are the most common source of incorrect results. For critical decisions, cross-reference with at least one additional source or professional consultation.
