debt avalanche method meaning

The debt avalanche is repaying debts in order of interest rate, highest first, regardless of how large each balance is. It is the arithmetically optimal order, because every spare rupee goes against the most expensive money you owe. Its rival, the debt snowball, clears the smallest balance first for the motivation of an early win — it costs more in interest, but some people stay with it better.

what interest rate do indian credit cards charge on an unpaid balance

Revolving credit card balances in India typically carry around 3% to 4% a month, which annualises to roughly 36–48% — the most expensive borrowing most households ever take on. Interest runs on the full outstanding balance, not just the part you failed to pay. Once a balance revolves, the interest-free period stops applying and fresh purchases start accruing interest from the day they are made.

paying only the minimum due on a credit card means

Almost nothing comes off the principal. On ₹1,00,000 outstanding at 42% a year, a 5% minimum of ₹5,000 is largely swallowed by about ₹3,500 of interest, leaving roughly ₹1,500 against the balance — over eight years to clear even if you never spend on the card again, and more interest paid than the original purchase. The minimum due keeps the account from going delinquent; it is not a repayment plan.

should I prepay my home loan or invest the money instead

The comparison is between a certain, tax-free return equal to your loan rate and an uncertain, taxable return from investing. At roughly 8.5% the home loan is the one common Indian debt where that comparison is genuinely close — longest tenure, lowest rate on offer, and up to ₹2 lakh of interest deductible under Section 24 if you are in the old regime. Everything above it on the rate ladder, from cards to personal and gold loans, clears the bar comfortably.

is there a prepayment penalty on a home loan in india

Floating-rate home loans to individual borrowers for non-business purposes carry no foreclosure or prepayment charge — the RBI bars lenders from levying one. Fixed-rate loans are treated differently and can attract a charge, so the loan agreement is the document to check before paying anything down. When you do prepay, ask the bank to shorten the tenure rather than reduce the EMI, because the interest saving lives in the shorter tenure.

Which loans to clear before you invest a rupee

Paying off a loan is an investment. The return is exactly the interest rate, it is guaranteed, and it is tax-free. That framing settles most of the "should I invest or repay?" question before any spreadsheet is opened — the only remaining issue is which loans clear the bar.

Think of it like this

Filling a leaking bucket

You would not stand at a tap filling a bucket with a hole in it, congratulating yourself on how fast the water is going in. You would plug the hole first, then fill it.

In the market

A credit card at 42% is a large hole. Investing at an uncertain 12% while paying a certain 42% is filling a leaking bucket faster, which is not the same as filling it.

The order, by rate

Debt	Typical rate	Clear before investing?	Note
Credit card revolving balance	36–48%	Always, immediately	The most expensive money most Indians ever borrow
Personal loan	11–24%	Almost always	Rarely beaten by any investment
Consumer / no-cost EMI	0–18%	Usually	"No cost" often means the discount was removed instead
Gold loan	9–18%	Usually	Short tenure, and the collateral is family jewellery
Car loan	9–12%	Probably	Depreciating asset, so no offsetting appreciation
Education loan	8–12%	Partially	Section 80E allows full interest deduction for eight years
Home loan	8–9.5%	Usually not	Longest tenure, lowest rate, possible Section 24 relief

The credit card minimum payment

Worked example

What "minimum due" actually means

₹1,00,000 outstanding at 42% a year

Minimum dueTypically 5% of the balance₹5,000

Interest that month42% ÷ 12, on the full balance₹3,500

Principal repaidWhat the payment actually reduced₹1,500

Time to clear at minimumsAssuming you never spend on it againOver 8 years

Total interest paidOn a ₹1 lakh purchaseMore than the original balance

Also, from the first missed dateThe interest-free period disappears entirelyInterest on new spends

Paying the minimum is not slow repayment; it is barely repayment at all. Once a balance revolves, every new purchase starts accruing interest from the day it is made — the grace period does not apply while the account carries a balance.

Try the same prepayment in year two and in year fifteen of a home loan. The difference shows why "prepay early or not at all" is more than a slogan.

Why the home loan is the exception

The rate is low. At 8.5% it sits below the long-run return of Indian equity, so the expected value favours investing — with the important caveat that "expected" is doing real work in that sentence.
Relief may apply. Up to ₹2 lakh of interest is deductible under Section 24, but only in the old regime. Under the new regime a self-occupied home gets nothing, which raises the effective cost of the loan.
It is the cheapest large loan you will ever be offered. Prepaying it and later needing money means borrowing again, at a worse rate, against the same house.
But interest is front-loaded. In the first years, most of the EMI is interest — so if you are going to prepay at all, early prepayment removes far more interest than late.

Simple bhasha mein

Chhed wali balti

Balti mein chhed ho toh aap tez paani nahi daalte, pehle chhed band karte ho. Credit card 42% pe chal raha hai aur aap 12% ki ummeed mein SIP badha rahe ho — loan chukana pakka 42% return hai, bina tax ke. Ghar ka loan alag baat hai, woh sabse sasta hai.

What to remember

Repaying debt is an investment returning exactly the interest rate, guaranteed and tax-free.
Clear cards and personal loans before investing anything at all.
Minimum payments on a card take eight years and cost more than the original balance.
The home loan is the usual exception — low rate, long tenure, possible relief.
When prepaying, reduce the tenure rather than the EMI, and keep the emergency fund intact.
