The job this tool does, and who does it today
Every lending conversation opens with the same question: how much can I get. The answer decides whether the applicant keeps talking, and it is asked before anyone has seen a payslip, a bank statement or a bureau report.
Today that answer is produced by a branch executive, a DSA in a car showroom, or a tele-caller with a notepad. Some do the arithmetic properly. Many quote a figure from the last similar case they handled, or use a generic calculator that ignores the applicant's existing obligations entirely. The number is often optimistic, which feels helpful for ten minutes and damaging six weeks later when the sanction letter says something smaller.
An EMI eligibility checker's job is to make that first number defensible: same inputs, same policy parameters, same arithmetic, whoever is asked.
