How the IPO UPI Mandate & Blocked Amount Calculator works

When you submit an IPO bid via UPI/ASBA, your broker sends a mandate (collect) request to your UPI app for bid price × lot size × number of lots. This is a block/lien on your bank balance, not a debit — the money stays in your account and only moves out if you're allotted shares.

Two separate deadlines apply on the issue's closing day: your broker/bank must submit the bid by 4:00 PM, and you must approve the UPI mandate request by 5:00 PM. Many brokers set an earlier internal cut-off to leave buffer before the 5 PM SEBI deadline, so don't wait until the last minute — a mandate approved late is auto-rejected with no exceptions.

Frequently Asked Questions

What is a UPI mandate amount in an IPO?

It's the amount your UPI app blocks (lien-marks) in your bank account when you submit an IPO bid — calculated as bid price × lot size × number of lots. It is not debited unless you're allotted shares.

By when must I approve the UPI mandate?

SEBI requires approval by 5:00 PM on the issue's closing day (bid submission itself is due by 4:00 PM). Many brokers set an earlier internal cut-off, so approve as soon as the request arrives rather than waiting.

What happens if I don't approve the mandate in time?

The mandate expires and your application is automatically rejected — there is no partial fill or extension. You would need to reapply if the issue is still open.

Is money debited the moment I approve the mandate?

No. Approving only confirms the block/lien on the funds. The amount is debited only after allotment is finalised; if you don't get allotted, the block is released automatically, typically within 1-2 business days.

Can I cancel or modify a UPI mandate after approving it?

You can withdraw or revise your bid through your broker before the issue closes, which cancels the old mandate and (if revised) triggers a fresh one. Once the issue closes, the mandate cannot be modified.
