Estimate the interest cost of funding an HNI / NII IPO application with borrowed money, and the net gain after GMP profit for large IPO bids.
Interest cost = amount × rate% × days ÷ 365Per-day cost = interest ÷ daysIf you enter expected GMP profit, net gain = GMP profit − interest costHNI funding fills the gap between the 2 lakh retail cap and crore-level bids: lenders finance NII applications for the few days money stays blocked, charging daily interest. Searches for IPO funding interest rate and ASBA vs IPO funding peak with every large issue because the math decides whether the GMP profit survives the interest.
Enter the application amount, the lender's annual rate and blocked days. The tool shows total interest, per-day burn and, if you add expected GMP profit, the net after funding cost. Remember interest accrues even on fully refunded, unallotted applications.
Know your bucket: 2 to 10 lakh bids sit in sNII (one-third of NII reservation) and above 10 lakh in bNII (two-thirds). Allotment probability and funding economics both change across that line, so run the Allotment Odds calculator alongside.
HNI / NII applications require large amounts; many investors use short-term funding and rely on GMP profit to cover the interest.
Count from the day funds are blocked (ASBA) until listing, typically 5–8 working days.
IPO funding rates are usually higher than home-loan rates and vary by lender, IPO size and demand — confirm your lender's per-day rate before bidding.
ASBA blocks your own bank balance with zero interest cost. Funding borrows the application amount, so interest accrues whether or not you get allotment.
Yes. Funding interest applies for the days your application money was deployed, even if the whole amount is refunded unallotted.
Non-institutional bids of ₹2–10 lakh are small-NII (one-third of NII reservation) and bids above ₹10 lakh are big-NII (two-thirds). Funding economics differ across the two.
