Questions

Frequently asked

Is the comparison fair?

We assume lumpsum and STP invest the same total cash as the SIP, but available today. That's the honest catch: lumpsum usually wins on paper precisely because it assumes you already have the full sum, which most people don't.

How is STP modelled?

As a lump sum parked and fed into equity over about a year, approximated with a small drag versus pure lumpsum. The exact figure depends on the parking instrument; see the methodology page.
