How long would it take for ₹5 lakh to grow into ₹1 crore with & without SIP?

If ₹5 lakh is invested as mutual fund lump sum at an assumed 12% annual return, it could take 27 years to grow to ₹1.07 crore before taxes, fees and inflation, NDTV Profit reported. However, to reach ₹1 crore sooner, one can combine a ₹5-lakh lump sum and ₹10,000 in SIPs every month at the same return for 18 years.
