Calculations follow official RBI & DICGC aggregation rules (₹5 Lakh per depositor per bank covering principal + interest).
How the DICGC FD Insurance Calculator & Multi-Bank Splitter Works
Managing deposit-insurance risk when investing ₹5 Lakh, ₹10 Lakh, or ₹50 Lakh in bank fixed deposits.
What is DICGC Deposit Insurance?
The Deposit Insurance and Credit Guarantee Corporation (DICGC), a wholly-owned subsidiary of the Reserve Bank of India (RBI), provides deposit insurance to commercial banks, small finance banks, and co-operative banks in India.
In the event of a bank failure or liquidation, DICGC insures each depositor up to a maximum of ₹5,00,000 (Rupees Five Lakh) across principal and accrued interest combined.
Why Reverse-Calculation Matters
Standard fixed deposit calculators only answer: "How much will my money grow?"
This tool answers: "How should I structure my fixed deposit portfolio today so that future interest compounding does not accidentally push my bank exposure beyond the ₹5 Lakh insurance limit?"
Example Portfolio Allocation Scenarios
| Capital Amount | Recommended Banks | Allocation Strategy | Insurance Protection Status |
|---|---|---|---|
| ₹5,00,000 (5 Lakh) | 1 - 2 Banks | Deposit ~₹4.0 Lakh to leave room for interest | 100% Insured |
| ₹10,00,000 (10 Lakh) | 3 Banks | Split ~₹3.3 Lakh per bank | 100% Insured |
| ₹20,00,000 (20 Lakh) | 5 Banks | Split ~₹4.0 Lakh per bank | 100% Insured |
| ₹50,00,000 (50 Lakh) | 5 Banks + Post Office | Fill bank safe capacity + route surplus to SCSS / POMIS | 100% Insured + Sovereign |
Real-Life Planning Examples
Scenario 1: I have ₹10 Lakh to deposit for 3 years
Putting ₹5 Lakh in Bank A and ₹5 Lakh in Bank B seems logical, but 7% interest adds ~₹1.15 Lakh interest per bank over 3 years. Maturity reaches ₹6.15 Lakh at each bank—leaving ₹1.15 Lakh per bank uninsured!
Safer Route: Divide across 3 banks (~₹3.33 Lakh each).
Scenario 2: I already have ₹3 Lakh in HDFC Bank
Adding a fresh ₹3 Lakh FD at HDFC Bank brings total principal to ₹6 Lakh—immediately exceeding the ₹5 Lakh limit even before interest is earned!
Safer Route: Limit fresh deposit at HDFC Bank to ~₹1.0 Lakh and place remaining capital in another bank.

Frequently Asked Questions (DICGC FD Insurance)
Understanding deposit insurance, aggregation rules, and multi-bank splitting
What is the DICGC insurance limit for bank deposits in India?
Under current Reserve Bank of India (RBI) guidelines, the Deposit Insurance and Credit Guarantee Corporation (DICGC) guarantees principal plus interest up to ₹5,00,000 (Rupees Five Lakh) per depositor per bank for deposits held in the same capacity and right.
Does DICGC deposit insurance include accrued interest?
Yes. DICGC insurance protects both your deposited principal and accrued interest combined up to ₹5 Lakh. If your principal is ₹4,80,000 and accrued interest reaches ₹50,000, your total exposure is ₹5,30,000—leaving ₹30,000 above the insured limit.
Does the ₹5 Lakh limit apply separately to every FD account?
No. The ₹5 Lakh limit applies per depositor per bank across all branches of that same bank combined. Multiple FDs, savings accounts, and recurring deposits at the same bank in the same ownership capacity are aggregated under one single ₹5 Lakh insurance cap.
What happens if I hold FDs in different banks?
Deposits held in different commercial banks carry independent ₹5 Lakh DICGC insurance caps. For example, holding ₹4.8 Lakh in Bank A and ₹4.8 Lakh in Bank B provides ₹5 Lakh insurance protection at each bank separately.
Why does this calculator use a planning safety buffer?
We recommend a configurable safety buffer (e.g. ₹4,95,000) below the official ₹5 Lakh threshold to absorb minor compounding variations or interest payout timing differences without accidentally breaching the insured limit.
Are Post Office deposits covered by DICGC?
Post Office savings schemes (SCSS, POMIS, NSC) are backed directly 100% by the Government of India (Sovereign Guarantee) under Act of Parliament, rather than DICGC bank insurance. Sovereign guarantee is an absolute sovereign backing.
