The 10-10-10 SIP rule suggests investing through a SIP for at least 10 years by assuming an average annual return of 10% and increasing the SIP contribution by 10% every year. If someone starts with a ₹10,000 SIP under the 10-10-10 SIP rule, then after ten years their ₹19.12 lakh of total investments would increase to around ₹30.45 lakh.
