About

A security deposit calculator is a specialized tool used by landlords and tenants to determine the exact amount of money to be returned at the end of a lease agreement. This process involves taking the original deposit amount, adding any state-mandated interest accrued over the tenancy, and subtracting allowable deductions for damages beyond normal wear and tear or unpaid rent. Using an AI-powered calculator ensures that the final itemized statement is professional and transparent. ContractMaker.ai enhances this process by providing a live editor where every calculation and deduction is shown via Track Changes, allowing both parties to see exactly how the final balance was derived. This level of detail helps prevent disputes and ensures that the final document meets the professional standards required for legal record-keeping and DOCX compatibility.
