₹10 lakh has just landed. What order should it go in?
No Sign-Up. No Paywall.
A windfall is the one moment when the whole balance sheet can be fixed at once, and the one moment people are most likely to decide with the part of the brain that wants a holiday. The order below is not moral advice; it is a ranking by return.
Why the Order Matters More Than the Choice
Almost every article about a windfall poses it as a choice: invest it, or clear the loan, or keep it aside. That framing is wrong, because the money can and usually should do all three in sequence. What matters is the order, and the correct order is decided by a single comparison: the certain return from removing a liability against the uncertain return from adding an asset.
Clearing a credit card revolving at roughly 36 percent a year is a risk-free, tax-free 36 percent return. There is no investment available to a retail investor that competes with that, and no argument about market timing that survives it. A personal loan at 15 percent is the same argument at a lower number and still comfortably ahead of any realistic equity expectation. A home loan at 8.5 percent is where the comparison genuinely becomes close.
The cushion sits second rather than first for a specific reason: without it, the next unexpected expense goes back onto the same high-rate credit you just cleared, and the windfall achieves nothing permanent. But holding a large cushion while carrying card debt is worse still, so the sequence is a small cash floor, then the expensive debt, then the full cushion, then investing.
Windfall Deployment Model
How the Sequence Is Built
The model puts a one-month cash floor ahead of everything, then clears any debt whose rate exceeds your expected investment return, then fills the cushion to your chosen number of months, then invests whatever remains. The floor exists because a household that clears every loan and holds no cash is one washing machine away from borrowing again at the rate it just escaped.
The comparison that drives step one is not close for most consumer debt. Repaying a loan produces a certain, tax-free return equal to its interest rate. An equity investment produces an uncertain, taxable return. A 15 percent loan therefore beats an 11 percent expected return by considerably more than the four point gap suggests, once certainty and tax are priced in. Where the loan rate is below the expected return, as with most home loans, the model leaves it alone and the decision becomes a genuine judgement about risk tolerance rather than arithmetic.
The last figure, what the invested portion becomes over your horizon, is there to keep the trade-off visible. Clearing debt feels like spending and investing feels like building, but the first is usually worth more. Seeing both numbers side by side is the point of the exercise.
What Changes the Answer
Whether the debt has a prepayment penalty
Floating rate home loans to individuals generally cannot carry a foreclosure charge under RBI norms, but fixed rate loans and many personal loans can. A penalty of two to four percent of the outstanding reduces the effective return from clearing it, and occasionally reverses the ranking against investing.
Tax deductions attached to the loan
A home loan carries deductions on interest and principal under the old regime, which lowers its effective cost. Under the new regime for a self-occupied property those benefits largely do not apply, so the same loan is more expensive in real terms and more worth prepaying.
Whether the windfall is taxed
A performance bonus is taxed at slab rates and arrives net. A maturity payout from a qualifying insurance policy, a PPF withdrawal or a gift from a specified relative may not be taxed at all. Enter the amount that actually reaches your account, not the headline figure.
Deploying a lump sum into equity all at once
Investing everything on one day carries timing risk that a SIP does not. Staggering the investable portion over six to twelve months through a systematic transfer plan removes most of that risk. Historically, investing immediately has slightly beaten staggering on average, but the average is not much comfort if your one day is the wrong one.
