Pausing or stopping a SIP: what a six-month break costs

What a skipped instalment really costs

Skipping a SIP instalment loses more than the instalment. It also loses the growth that instalment would have had for the rest of the SIP. That is why pausing early costs more than pausing late.

Take ₹10,000 a month for 10 years at an assumed 12% a year (the maths of the SIP calculator, not a forecast). With no break the value at the end is ₹22,19,300. Now skip six instalments:

You skipped ₹60,000 of instalments in each case. The cost is two to three times that, because the missing money would have compounded for years. The earlier the gap, the bigger the cost: the same logic as in the cost of delaying a SIP.

Pause beats stop

• Pause: many fund houses let you skip a few instalments (often one to three months at a time) and resume on their own. The facility and its limits differ by fund house, so check with yours.
• Stop: the SIP ends. Restarting means a new mandate, a fresh habit and, in practice, a longer delay than you planned.
• Reduce: often the best option. Cutting ₹10,000 to ₹5,000 for a lean stretch keeps the habit alive and loses far less than zero. Raise it again later, or use a step-up SIP to catch up.

Do not stop because the market fell

A falling market is when a SIP buys more units per rupee. Stopping then means you quit buying at lower prices and often restart only after the recovery. Behaviour does more damage than the maths here; our post on the psychology of wealth covers why.

Prevent the problem first

Most pauses come from cash-flow shocks. An emergency fund of a few months' expenses is what lets a SIP survive a job gap or a medical bill. If a SIP date falls just before salary day, move it to a day after the credit so the instalment does not bounce.

If you must stop

Stop the SIP, not the investment. Units you have already bought stay invested and need not be sold. Check whether the fund has an exit load before redeeming, and see how SIP redemptions are taxed so a hurried sale does not add a tax bill.
