Set a maximum EMI as a percentage of stable monthly surplus after all existing obligations and essential savings. Do not use gross salary. If the proposed loan crosses the red line, reduce the wedding budget rather than stretching tenure until the EMI looks acceptable.
Account for vendor payment timing
Wedding vendors often require advances months before the event. A loan disbursed too early creates extra interest; disbursed too late, it misses deposits. Build the borrowing date around the actual payment schedule and use savings for small early deposits where practical.
Cancellation risk
Read vendor refund policies. Borrowing to make non-refundable payments creates double risk if the event is postponed. Consider insurance only when the coverage genuinely fits the event and exclusions are understood.
The financial success of a wedding is simple: after the event, the household should still have emergency savings and an EMI that does not force new debt. Anything else is a warning to cut the event before increasing the loan.
