Setting up a Systematic Investment Plan (SIP) on Zerodha Coin or Groww is a great way to automate your wealth building. You link your bank via a UPI AutoPay or e-NACH mandate, and the money gets deducted effortlessly every month.
But what happens if your account is running low on cash and that auto-pay fails?
Does your SIP get canceled? Will you be fined? Here is the complete breakdown of the hidden costs of a failed SIP auto-pay and exactly how to fix it without breaking your investment momentum.
🚫 The Short Answer: What Happens Instantly?
If your auto-pay fails on the scheduled date, two things happen immediately:
- Your SIP order fails for that month: The platform will not buy mutual fund units for you during that cycle.
- Your SIP is NOT deleted: Missing one installment will not cancel your entire SIP. Your broker will simply try again automatically next month.
However, while Groww and Zerodha won't punish you, your bank absolutely will.
💸 The Hidden Hit: Bank ECS/NACH Bounce Charges
Neither Zerodha nor Groww charges a penalty for a failed SIP installment. They simply mark the transaction as "Failed".
The real financial penalty comes from your bank. Because an auto-pay mandate is a formal legal instruction, a failure due to insufficient funds is treated exactly like a bounced cheque.
Banks call this an ECS / NACH Bounce Charge, and it can quietly drain your account balance:
| Bank Name | Typical Failed Auto-Pay Charge (Per Failure) |
|---|---|
| SBI | ₹250 + 18% GST |
| HDFC Bank | ₹450 to ₹500 + 18% GST |
| ICICI Bank | ₹400 to ₹500 + 18% GST |
| Axis Bank | ₹500 + 18% GST |
The Flaw to Watch Out For: If you have 5 different mutual fund SIPs scheduled on the same day via the same mandate, and your account has insufficient funds, your bank might charge you 5 individual bounce fees. That can instantly wipe out up to ₹2,500 just in penalties!
🛠️ Step-by-Step Solutions: How to Fix a Failed Auto-Pay
If your auto-pay fails, don't panic. You can easily keep your investments on track using these options.
Solution 1: Make a Manual "One-Time" Payment
Both platforms give you a grace window to manually invest the missed amount so you don't lose out on the month's compounding.
- On Groww: Go to your Dashboard > Pending SIP Payments > Select the missed installment > Pay instantly via UPI or Net Banking.
- On Zerodha Coin: If the mandate fails, Coin keeps the order processing for up to 5 business days. You can manually fund your Zerodha trading account or pay via instant UPI to clear the order before it completely fails.
Solution 2: Pause or Modify the SIP Before the Due Date
If you know you are going to face a cash crunch next month, do not let the auto-pay run and bounce.
- Go to your active SIP settings on Groww or Coin at least 2 to 3 days before the scheduled date.
- Hit Pause to skip the upcoming month completely, or Modify the date to a time after your salary hits your account. There are zero charges for pausing or modifying a SIP.
🚨 The Ultimate Warning: The 3-Strike Rule
While missing one or two SIPs won't break your account, fund houses (AMCs) have a strict line in the sand.
If your auto-pay mandate fails for three consecutive months, the mutual fund company will automatically terminate your active SIP completely.
Your existing invested money will remain safe in the market, but your automated monthly investing streak will end, forcing you to set up a brand new mandate from scratch.
💡 Pro-Tip for InvestSeed Readers
To keep your bank account safe from unnecessary bounce charges, always make sure your funds are parked in your account at least 2 business days before your SIP date. Most systems check your opening account balance on the morning of the transaction, meaning adding money on the actual SIP day might still trigger a technical failure!
