RTGS: How It Works, Timings and Minimum Amount (2026)

Some payments are too large and too important to wait in a queue. When a business pays for property, settles a major supplier bill, or buys expensive machinery, the money needs to move fast and with certainty. RTGS is built for exactly this. It settles each large transfer on its own, in real time, so the amount reaches the other bank within minutes and cannot be reversed once done. This guide explains what RTGS stands for, how real-time gross settlement works, the two lakh rupee minimum, the 24x7 timings, the charges to expect, and the simple rule for choosing RTGS over NEFT.

What RTGS is

RTGS stands for Real Time Gross Settlement, and both halves of that name tell you something important. Real time means each payment instruction is processed the moment your bank sends it into the system, not collected and held for a scheduled batch. Gross means each transfer is settled individually and in full, one by one, rather than being bundled and netted off against other payments. Put together, RTGS is the system the Reserve Bank of India runs for moving large amounts between banks quickly and with finality.

Finality is the quiet strength of RTGS. Once a transfer settles across the RBI books, it is complete and cannot be pulled back. For large payments that is a feature, not a risk: the supplier or seller can trust the money has truly arrived and can release goods or complete a deal on the strength of it. That certainty is why RTGS is the standard rail for high-value business and property transactions across the country.

How RTGS works step by step

An RTGS transfer follows a short path, but unlike NEFT it does not wait for a batch. Here is what happens once you confirm a payment:

• You submit the transfer: you add the beneficiary with their account number and IFSC, enter an amount of two lakh rupees or more, and confirm.
• Your bank sends it immediately: instead of holding it, your bank debits your account and passes the instruction straight into the RTGS system.
• RBI settles it in real time: the Reserve Bank settles that single transfer on its books the moment it is received, individually and in full.
• The beneficiary bank credits at once: the receiving bank gets the settled instruction and credits the beneficiary, usually within minutes.
• Both sides get confirmation: you receive a reference number and the beneficiary sees the credit, giving both parties a clear record.

Because each transfer is settled on its own rather than waiting for others, RTGS is the quickest way to make a large payment land, and the reference number it produces is your proof that the money moved.

The two lakh rupee minimum

RTGS is designed for high-value payments, so it has a floor: you cannot send less than two lakh rupees in a single RTGS transfer. This minimum is what separates RTGS from the other rails. If a payment is below two lakh rupees, the system will not accept it as RTGS, and you would use NEFT or IMPS instead. On the upper side, the Reserve Bank does not set a fixed cap for the system, so RTGS can carry very large sums, though your own bank may apply its own per-transaction or daily limit that you can often raise on request.

The minimum shapes when RTGS makes sense. It is the rail for the big, single payment, not for a stream of small ones. If you find yourself wanting to send many smaller amounts, NEFT is the better fit because it has no minimum and online transfers are usually free. Think of RTGS as the tool you reach for a few times a month for the large payments, not the one you use for everyday transfers.

RTGS timings

Like NEFT, RTGS is now available around the clock. The system runs 24 hours a day, seven days a week, including Sundays and public holidays. Because settlement is in real time, a transfer you send generally reaches the beneficiary's bank within minutes rather than waiting for a batch. This all-hours availability is a real advantage for businesses that close deals or make payments outside normal banking hours, because a large, urgent transfer no longer has to wait for the next working day.

Two practical points remain. When you add a new beneficiary, some banks apply a short cooling period before you can send a large amount to them for the first time, so add an important payee a little ahead of the payment. And for exceptionally large sums, a bank may have its own internal checks or windows, so if you are moving a very large amount for the first time, a quick call to your relationship manager or branch confirms there will be no surprise hold.

RTGS charges

For RTGS transfers you initiate online through net banking or a mobile app, banks generally do not charge under current Reserve Bank direction, which keeps large online payments cost-free for most account holders. Where a charge can still appear is a branch counter transfer, and it is usually a flat fee for the transaction rather than a percentage of the amount, since RTGS is high value by design. Current and business accounts may have their own schedule that differs from a savings account. As with all bank charges, these are revised from time to time, so treat any figure as indicative and confirm the current RTGS charges with your bank, particularly on a business account, before you make a large transfer.

RTGS vs NEFT: which to choose

The choice between RTGS and NEFT comes down to two questions: how large is the payment, and how urgently must it settle. This comparison lays the two rails side by side:

The simple rule: if the payment is two lakh rupees or more and needs to clear right away with finality, use RTGS. For everything else, including any amount below two lakh rupees, NEFT does the job and settles in the next batch. Many businesses use both in the same week, RTGS for the occasional big payment and NEFT for the steady stream of routine ones.

Using RTGS safely in a business

Because RTGS moves large amounts and cannot be reversed, care with the details matters even more than usual. Verify the beneficiary account number and IFSC from an official document such as a cancelled cheque, not from a number pasted into a chat, and confirm the registered name your bank shows before you approve the transfer. For a very large payment, it is worth a phone call to the beneficiary to confirm the exact account, since a wrong detail on a big RTGS is far harder to recover than on a small transfer.

Keep good records on your side too. Note the UTR or reference number RTGS gives you and attach it to the invoice or contract the payment settles, so you can prove the transfer instantly if a question arises later. If you are handling both large outgoing payments and money owed to you, keeping billing and collection in one place helps; our GST billing software ties each payment to its invoice, and our guide to how to accept online payments covers the collection side.

The bottom line

RTGS is the rail for the big, important payment: it settles each transfer of two lakh rupees or more in real time, one by one, with finality, and it works around the clock. Reach for it when size and speed both matter, and use NEFT for routine transfers and any smaller amount. Confirm your bank's current charges and limits before a large transfer, and always double-check the beneficiary details, because RTGS cannot be undone.
