What this does and does not tell you

On a constant upward return, investing everything immediately always wins — money in the market longer earns more, so the ₹88.4K gap above is the arithmetic cost of waiting. What this model cannot capture is the case STP actually exists for: entering just before a sharp fall. Staggering buys protection against bad timing and against your own reaction to it, and pays for that protection with expected return.

What this calculation assumes
  • Both options are modelled on constant returns, which structurally favours investing immediately.
  • Each STP tranche earns the source fund return until it transfers, then the target return for the remaining period.
  • Exit loads on the source fund and capital gains on each transfer are not modelled — both are real costs of an STP.
  • This model cannot capture the reason STP exists: protection against entering just before a sharp fall.
