Digital zero balance accounts have become the default entry point into banking for a large chunk of India's digitally active population. These accounts suit students, professionals and homemakers alike, letting anyone access everyday banking without being charged for wanting flexibility on the balance they keep.
But not all accounts offered in the market are built the same way. While they all seem to have identical onboarding processes and similar apps, there are three popular kinds of banks that customers often come across. These include universal bank, small finance bank, and payments bank.
Against this backdrop, Quantum+ and slice offer the most flexible zero-balance account terms; Kotak 811 and Quantum+ pair their savings accounts with full stack banking products (FDs, loans, FD-backed credit cards); Airtel and Jio Payments Bank suit transactional/UPI use. Here's the full comparison:
1. At a glance: How do the five zero balance accounts compare?
Quantum+ (IDFC FIRST Bank) | Kotak 811 | slice | Airtel Payments Bank | Jio Payments Bank | |
Account type | Zero-balance savings a/c, universal bank | Zero-balance digital savings a/c, universal bank | Zero-balance savings a/c, slice Small Finance Bank | Zero-balance savings a/c, Payments Bank | Zero-balance savings a/c, Payments Bank |
Minimum balance | There is no minimum balance requirement and no maintenance fees | Nil on base variants; ₹10,000 AMB requirement on certain premium variants | There is no minimum balance requirement | There is no minimum balance to be maintained in zero-balance savings accounts | There is no minimum balance to be maintained in zero-balance savings accounts |
Interest rate | Slab-based interest up to 7% p.a. is applicable on balances between ₹3 lakh and ₹25 lakh | 2.5% p.a. flat, up to 5.50% p.a. via ActivMoney sweep | Flat rate = 100% of RBI repo rate on the whole balance, currently 5.25% | 1.5%–6.5% p.a., slab-based | Slab-based: 0.5% up to ₹1L, 4% above |
Interest crediting | Daily calculation, monthly credit | Calculated on daily balance; paid quarterly | Interest is paid daily | Daily calculation, monthly credit | Daily balance based; credited quarterly |
Debit card | Zero issuance charges, | Free first virtual card; physical card ₹299–399 p.a. depending on variant, and a VISA Platinum free on the Super Account | Virtual card standard; physical card issued on request | Free virtual card; physical card ~₹299–349 p.a.; annual maintenance charge applies | Platinum Debit Card offered |
Companion credit card | Quantum+ Credit Card; FD-backed and lifetime free; no joining fee, credit limit: 100% of FD | 811 #DreamDifferent Credit Card is FD-backed, lifetime free, limit up to 90% of FD | UPI-enabled credit card with no joining fee or annual charges | Payments Banks cannot issue credit cards | Not available |
ATM access | Free at IDFC FIRST Bank ATMs; capped free transactions elsewhere; Daily ATM withdrawal limit: ₹1,00,000 | Daily ATM cash withdrawal is ₹25,000 on the Zero Balance Account | Standard network access through the physical card | 5 free transactions/month at own and select other-bank ATMs, charges beyond that | Access to over 70,000 Jio ATMs and cash points across the country |
Account opening | Fully digital, Video KYC, in minutes via app | Fully digital, no branch visit for base variants | Fully digital, instant, zero paperwork | Digital via Airtel Thanks app or offline at banking points | Digital via MyJio/JioFinance app or offline at outlets |
Banking breadth | Full universal-banking stack: FD, loans, cards, investments, insurance, branches | Full universal-bank stack via parent Kotak Mahindra Bank | Small Finance Bank stack: savings, FD, UPI credit card, personal loans | Payments-bank only: no lending or in-house FDs | Payments-bank only; Savings Pro adds a mutual-fund auto-invest layer |
Key differentiator | Zero-AMB account on a full-service bank, slab-wise interest offered up to 7%; lifetime-free FD-backed credit card | Long-standing digital account now built around ActivMoney's FD-sweep rather than a high headline rate | A flat repo-linked rate that changes with RBI policy | Telecom-scale agent network for cash-in/cash-out | Reliance–SBI-backed JV with Jio's retail footprint and an overnight-fund investing option |
The widest gap between these five is not their interest rate offerings, but the service range capabilities. Quantum+ and Kotak 811 sit with universal banks. This means that their savings account is a gateway to loans, FDs, and investments via the same login. slice now sits on its own small finance bank licence with growing services. Airtel Payments Bank and Jio Payments Bank operate under RBI's Payments Bank framework, and offer limited lending services.
2. Interest rates: Which account gives you more on your savings?
Payments banks are capped on deposit size. As a result, the comparison here uses a limited balance comparison, assuming ₹1,50,000 kept through the year. At ₹1.5 lakh, the accounts produce different outcomes as their interest structures work differently.
- Quantum+: The first ₹3 lakh is calculated at the base 2.5% interest rate slab, so ₹1.5 lakh earns roughly ₹3,750/year. Given the account offers monthly interest credit, the compounding impact pushes the results slightly higher.
- Kotak 811: The flat 2.5% rate gives the ₹3,750/year on the base account.
- slice: The rate applies to the entire balance, which means ₹1.5 lakh at 5.25% (current repo rate) works out to roughly ₹7,875/year.
- Airtel Payments Bank: The published range is 1.5%–6.5% p.a. depending on the balance slab. The first one lakh earns 1.5% rate, which means the total comes around to be ₹4,750/year.
- Jio Payments Bank: ₹1.5 lakh at actual slab rates earns ₹1 lakh × 0.5% + ₹0.5 lakh × 4% = ₹500 + ₹2,000 = ₹2,500/year.
Interest calculations are illustrative and based on the respective prevailing rates and published slabs as of October 2026. Actual interest may vary based on daily balance, rate changes, applicable slabs and account terms
To be clear, Quantum+ and Kotak 811 reward progressively larger balances. The Quantum+ account's higher interest slab applies as soon as the balance crosses a specified threshold.
Example:
Quantum+ Interest rate slabs
- ₹0 to ₹3 lakh: 2.50% p.a.
- Above ₹3 lakh up to ₹25 lakh: 7.00% p.a.
Balance | Interest per year |
₹3,00,000 | ₹7,500 (all at 2.50%) |
₹4,00,000 | ₹14,500 (₹3L at 2.50% plus ₹1L at 7.00%) |
3. Zero balance: Are all five accounts equally flexible?
While all five accounts are “zero-balance”, here's where the difference lies:
- Quantum+ has no AMB condition: You are not required to maintain any minimum average balance in your Quantum+ Savings Account.
- Kotak 811: This is also genuinely zero balance on its Limited KYC, Lite and Full KYC variants. The 811 Edge variant has a ₹10,000 AMB requirement with a shortfall penalty.
- slice: slice also offers an unconditionally zero balance product.
- Airtel Payments Bank: While the account is zero balance, it is not designed to hold large sums as per the Reserve Bank of India's guidelines.
- Jio Payments Bank: It comes with zero balance feature up to a point. Balances above a threshold are automatically swept into a linked partner-bank sweep account at the end of day.
4. Debit cards & ATM access: What do you actually get?
Physical/Virtual Card Availability
- Quantum+ comes with a physical debit card that is free for the first year, with an annual fee applicable from the second year onwards. Kotak 811 offers the first virtual debit card for free, while the physical debit card is available at an additional cost.
- Airtel Payments Bank's virtual card issuance is free, but the physical card comes with a fee. The maintenance charges are applicable on both cards. Jio Payments Bank bundles a Platinum debit card into the account rather than treating it as an add-on.

5. Opening an account: Which one is easiest to get started with?
All five accounts can be opened without a branch visit for a standard retail customer:

7. Which account stands out for which type of user?
Focus on savings returns: Quantum+ is the stronger choice for growing savings, particularly once your balance crosses ₹3 lakh. Slice still leads at moderate balances, with a flat, repo-linked rate on the entire balance.
- Transactional banking: Airtel Payments Bank and Jio Payments Bank are built for everyday, transactional banking. You can use them for paying bills, recharges, small UPI transfers, etc.
- For an app-first experience: Quantum+ delivers a paperless account opening experience and several in-app account features, with a fuller banking stack behind the same app. Slice and Kotak 811 offer similar paperless opening and in-app features.
- For ATM/card usage: Quantum+'s ₹1 lakh daily ATM limit and access at its own and other bank's network can be a leading choice.
- For broader banking (FDs, loans, investments, credit card): Quantum+ and Kotak 811 come with the full universal-bank facilities behind their zero-balance account from day one.
8. Final Comparison: Which Zero Balance Savings Account Should You Choose?
If a no-conditions zero balance matters most: Quantum+ and slice are the top options for you due to their ease of usage and no minimum balance requirement at any tier.
- Account with a real banking relationship: Quantum+ and Kotak 811 are built for offering the convenience of a zero balance account while facilities of FDs, lifetime-free credit card, and personal or home loans all at one place.
- If interest rate is priority: slice's repo-linked flat rate is the most transparent of the five brands compared here and may help you save significantly on your balance.
- For daily needs: For simply paying bills or doing recharges, while keeping limited or no balance in the account, Airtel Payments Bank or Jio Payments Bank's agent networks come with a genuine advantage.
- If you are interested in cashback, zero joining and annual fee: Quantum+ is an FD-backed card that comes with many features such as up to 2% cashback, zero joining and annual fee, making it an ideal option for everyday spending.
Customers must understand that the five accounts operate with different propositions and banking models. A universal bank's zero-balance account, a small finance bank's zero-balance account, and a payments bank's zero-balance account are different products even if they seem similar in marketing. The right choice for you will depend on what your priorities are as a customer.
