Borrowing decision guide
Use a clear framework for deciding whether surplus cash should reduce debt or remain invested for a potentially higher but uncertain return.
Model your loan repaymentPrepayment gives a relatively certain saving based on the loan rate. Investing preserves liquidity and may produce a higher return, but the outcome depends on time horizon, taxes, volatility and risk tolerance.
How to use this guide
Compare the effective after-tax investment return with the loan’s effective interest cost, not a headline return against a headline rate. Prepayment is a relatively certain saving; investment returns are estimates and can be negative over shorter periods.
Do not use all liquid savings for prepayment if it leaves no reserve for income shocks or near-term expenses. Separate emergency money from surplus cash before making the decision.
Review lender charges, part-prepayment limits and whether the payment reduces tenure, EMI or both. Ask for an updated amortisation schedule so the interest saving is measurable.
Money needed in the next few years should not depend on volatile assets. A long investment horizon can support more risk, but only when the loan and emergency plan remain manageable.
Home-loan tax benefits, investment taxation and the ability to access the money can change the outcome. A slightly lower expected return can be worthwhile when liquidity has real value.
A practical approach can combine a planned prepayment with regular investing when both debt reduction and long-term goals matter. Automate the chosen split and review it when income or rates change.
Common questions
It generally avoids future interest at the applicable loan rate, subject to the loan terms and any charges. It is not the same as a market investment return.
Not automatically. Keep essential insurance, emergency savings and important long-term contributions in place before directing surplus cash to prepayment.
Reducing tenure usually saves more interest when the EMI remains affordable. Ask the lender to show both scenarios using the same prepayment amount.
