Sweep-in Interest Benefit Formula

Interest Gain = FD Interest (Swept Excess) + Savings Interest (Threshold) - Normal Savings Interest

Calculates the additional interest earned by automatically sweeping excess savings account balance into a linked FD.

Worked Example: ₹1 Lakh balance (₹25k threshold, 3% savings rate, 7.2% FD rate, swept for 90 days)

Savings interest: ₹185. FD interest on ₹75k excess: ₹1,332. Gain over standard savings: **₹778**.

Sweep-in FDs: Maximizing interest on your idle savings balance

Karan kept an average balance of ₹1 Lakh in his savings account earning 3% interest. He frequently needed instant access to the cash, so he did not book a fixed deposit. He then activated the Sweep-in FD facility.

The bank set a ₹25,000 threshold. The excess ₹75,000 was automatically swept into a linked FD earning 7.2% interest. After 90 days, Karan earned ₹1,517 in interest, compared to only ₹739 normally, yielding an extra ₹778.

Sweep-in FDs automatically transfer balances exceeding a threshold into high-interest FDs, while keeping the cash fully liquid for savings withdrawals.

Activate sweep-in limits on your primary account to maximize returns on idle savings without losing liquidity.

Frequently Asked Questions

What is a sweep-in fixed deposit?

A sweep-in FD links your savings account to a fixed deposit. Balance exceeding a set limit is automatically converted into an FD to earn higher interest.

Is sweep-in money fully liquid?

Yes. If your savings balance falls below zero or you swipe your card, the bank automatically breaks a portion of the FD to cover the deficit with zero manual effort.

Do sweep-in FDs charge exit penalties?

Most banks do not charge exit penalties for sweep-in withdrawals, but interest is only paid for the exact days the swept balance remained in the FD.
