Home Loan + SWP Stress Test
SIP vs SWP vs Home-Loan Prepayment
See the different jobs of SIP, SWP and home-loan prepayment and avoid comparing contribution, withdrawal and debt-reduction tools as equals.

Direct answer
How do SIP, SWP and home-loan prepayment differ?
SIP contributes money to investments, SWP withdraws money from investments and prepayment reduces debt principal. They solve different cash-flow problems and should be compared by the household goal, risk and liquidity—not by one headline percentage.
Worked example
A borrower may prepay part of a bonus, keep an EMI reserve and continue a smaller SIP. Using an SWP to pay EMI is a separate strategy that adds sequence risk.
What to check
- SIP builds a corpus; SWP consumes or distributes it.
- Prepayment creates a predictable interest saving.
- A blended choice can protect both liquidity and debt reduction.
How the calculator approaches it
- 1.Calculate the reducing-balance home-loan EMI from principal, rate and tenure.
- 2.Treat that EMI as a monthly withdrawal from the investment corpus.
- 3.Apply return drag and compare a steady path with a bad-first-year path.
- 4.Check ending corpus and keep a separate liquid EMI reserve.
Important limitation
Market returns are variable, while the EMI is contractual. A 12% return is an assumption—not a promise—and an early market fall can damage an SWP plan even when the long-run average looks adequate.
