How to Compare Savings Accounts

By Ratan Updated: 17 Oct 2026
Retail banking guide to evaluating savings accounts: daily balance interest calculation, Average Monthly Balance (AMB) non-maintenance penalties, debit card fees, and DICGC insurance.

Overview

Evaluating Modern Retail Savings Bank Accounts

A savings bank account serves as the primary cash hub for receiving salaries, executing daily UPI transactions, and managing household liquidity. However, keeping funds in low-yield legacy bank accounts earning sub-inflation returns while paying high debit card annual maintenance fees and balance penalty charges erodes savings. Comparing account features helps you find the right balance of yield, service, and safety.

1. Key Comparison Metrics Across Bank Categories

Banking Category Average Interest Rate Typical AMB Requirement Service Quality & Digital Infrastructure Risk Profile
Top Public Sector Banks (e.g., SBI, PNB, BoB) 2.70% to 3.00% Zero to Low (₹1,000 to ₹3,000; SBI has zero AMB on regular savings) Extensive rural/semi-urban branch network; moderate digital app stability. Sovereign stability; too big to fail.
Major Private Sector Banks (e.g., HDFC, ICICI, Axis) 3.00% to 3.50% Moderate to High (₹10,000 to ₹25,000 in metro branches) Seamless mobile banking apps, instant card services, priority wealth desks. High domestic systemic importance (D-SIBs).
Small Finance Banks (e.g., AU, Equitas, Ujjivan) 5.00% to 7.25% (tiered by balance) Flexible (Zero balance options to ₹5,000) Modern digital interfaces, competitive rates to attract deposits. Covered under same RBI DICGC ₹5 Lakh insurance guarantee.

2. The Daily Balance Interest Advantage

  • Daily Balance Compounding: Because interest is computed on end-of-day balances, depositing large surplus funds even for a few days before tax or investment payments earns interest.
  • Auto-Sweep (Sweep-in) Facility: Choose an account featuring an automated sweep-in facility. When your savings balance exceeds a set limit (e.g., ₹25,000), the surplus automatically converts into short-term fixed deposits earning higher rates, while maintaining complete liquidity for payments.

3. Hidden Fees and Charges to Audit

  1. Debit Card Annual Maintenance Charges (AMC): Banks charge annual debit card fees ranging from ₹150 to ₹750 + GST. If you use UPI exclusively, opt for a basic Rupay Classic debit card or request a zero-annual-fee virtual debit card.
  2. Cash Deposit and Withdrawal Limits: Check monthly free branch transaction allowances. Many private banks restrict free branch cash deposits to 3 or 4 per month, charging fees on subsequent visits.
  3. SMS Alert Charges: Verify whether the bank levies quarterly SMS alert fees (₹15 to ₹25/quarter) or provides free regulatory alerts.

Frequently Asked Questions

Under RBI regulations, savings account interest is calculated on a daily end-of-day balance basis using the formula: Interest = (Daily Balance × Annual Interest Rate) / 365. The accumulated interest is officially credited to your account quarterly (or monthly in select new-age private banks).
AMB is not a requirement to keep a fixed minimum amount in your account every single day; it is the mathematical average of your end-of-day ledger balances over all days of the calendar month (Sum of Daily Balances / Number of Days). If your average falls below the bank's minimum threshold (e.g., ₹10,000 in metros), banks levy monthly non-maintenance penalty charges.
The Deposit Insurance and Credit Guarantee Corporation (DICGC)—a wholly-owned subsidiary of the RBI—insures bank deposits up to a statutory limit of ₹5,00,000 per depositor per bank (inclusive of both principal and accrued interest) across all savings, current, and fixed deposit accounts in the event of bank liquidation or license cancellation.
