Level 1 · Module 2 · Banking
Banks, Accounts & Interest
Where your money actually sleeps at night, and what it earns while sleeping.
In this lesson
What you'll be able to do
- Distinguish savings vs current accounts
- Name the main types of banks in India
- Explain simple vs compound interest
Think about it
Your bank pays you around 3% and lends the same money at 9%. Is that unfair, or is that the business?
Story
Let's picture it
A bank is a middleman for trust. It takes small deposits from thousands of people, promises them safety and a little interest, and lends the pool to borrowers who pay more interest. The gap, the net interest margin, is the bank's income. Your deposit is not idle; it is quietly funding someone's shop, tractor or home.

Savings vs current account
Savings account
For individuals · earns interest · transaction limits
Current account
For businesses · usually no interest · high transaction volume, overdraft possible
Fixed deposit
Locked for a term · higher rate · penalty on early exit
Recurring deposit
Fixed monthly amount for a term · disciplined saving
Plain English
The simple explanation
India's banking system includes the RBI (the regulator), public sector banks, private banks, foreign banks, regional rural banks, cooperative banks, small finance banks and payments banks.
Simple interest is earned only on the principal. Compound interest is earned on principal plus previously earned interest, that difference is the entire magic of Level 2.
Payment rails matter: UPI is instant and free for small retail transfers, IMPS is instant and 24×7, NEFT settles in batches, and RTGS is for large amounts (₹2 lakh and above) settled in real time.
Real world
DICGC deposit insurance
Bank deposits in India are insured up to ₹5 lakh per depositor per bank by DICGC. That's a real, checkable safety net, and a good reason to know which bank holds what.
Watch out
Common mistakes
- Keeping large idle balances in savings for years
- Not knowing your minimum-balance penalty
- Using RTGS/NEFT when UPI or IMPS would be instant and cheaper
Did you know?
Payments banks (like India Post Payments Bank) can accept deposits but cannot lend, a very different business from a normal bank.
Your turn
Mini challenge
Open your banking app and find three things: your interest rate, your minimum balance requirement, and last month's total charges.
