You will cut down on your dosas and filter coffees and you will pay big money in interests for your credit cards and loans. That is being plain stupid.
Here is my guiding principles of not going the penny wise road. I look for the big rocks and not the sand and gravel in the big picture (I hope you know the big rocks story of Steven Covey. If not catch it here).
A student loan of 100,000 (in whatever currency) at 5% interest rate is costing you about 160,000 (in whatever currency) in 20 years term. Do the math for your car loan, home loan and more. It sounds like a great idea to go with a loan (ease of one time burden) but over a period of time, you are buying the same thing for a lot more money in the name of convenience. That is being pound foolish. In saving more go for the big rocks first and then we can worry about sand and gravel on the way.
🥂to big rocks!
Interesting but karthi is loan a better way to buy if we have money. Example lets say today we have 1,60,000 and want to buy a car. Taking a loan at 8% interest for 8 years final value would be ₹296,148.83 and keeping that 1,60,000 in equities for 15% would be ₹489,443.66. Hence, I have the car and the amount back too isn't it?
