Invest vs Prepay Home Loan
Home-Loan Rate vs Investment Return
Learn why an 8% home loan and 12% expected investment return do not create a guaranteed 4% profit after tax, costs and risk.
Direct answer
Can I subtract the home-loan rate from expected investment return?
Only as a rough starting point. Loan interest avoided is comparatively certain, while investment return is variable and affected by tax, costs, time horizon and sequence; the two headline percentages are not equivalent.
Worked example
A 12% gross assumption minus 1% drag is 11%, but the realised path can still underperform an 8.5% prepayment saving over a particular period.
What to check
- Compare like-for-like time periods.
- Use after-tax, after-cost investment assumptions.
- Account for volatility and liquidity value.
How the calculator approaches it
- 1.Calculate remaining EMI interest without a prepayment.
- 2.Apply the lump sum to principal while keeping EMI unchanged.
- 3.Calculate interest saved from the shorter estimated tenure.
- 4.Compound the same lump sum at the after-drag investment return and compare gains.
Important limitation
Prepayment savings are comparatively predictable; investment gains are not. Preserve emergency liquidity and separately account for verified tax benefits and charges.
