Why holding excessive idle money in 3-4% savings accounts guarantees negative real returns after taxes and inflation.
Holding excess cash in a 3% savings account feels safe, but it is a guaranteed loss of wealth. After 6% inflation and 30% income tax, your real purchasing power declines by 3-4% every year. While you should always keep 3-6 months of expenses for emergencies, keeping surplus wealth in savings accounts destroys millions in lost compounding over a lifetime.

| 15 Years | ₹14,48,000 | ₹6,04,000 | ₹54,73,000 | ₹22,83,000 |

A 30-year-old keeps an unnecessary ₹15 Lakhs cash cushion in a savings account earning 3% for 15 years instead of deploying ₹10 Lakhs of it into a Nifty 50 index fund.
💡 Takeaway: Excess safety is the single most expensive luxury in personal finance.
Deploying via a 12-18 month Systematic Transfer Plan (STP) removes timing risk while ending the cash drag.
