List each disbursement date and amount. Education loans are often drawn in tranches, so interest may start at different times.
Read the accrual clause. Identify whether interest is calculated on disbursed principal and how frequently it is posted.
Track capitalisation. Note when unpaid interest is added to principal, if applicable.
Include concessions. If servicing interest earns a rate benefit, model the benefit and the cash you must pay.
Compare debt at EMI start and total repayment. That reveals the cost difference more clearly than the product label.
Decision rule: ask for an amortisation or illustrative schedule and verify that your calculation reaches roughly the same opening repayment balance.
