Mathematical Foundation

Three layers of retirement logic.

Each calculator has a distinct purpose, and the combined planner ties them together into a more practical retirement story.

SIP accumulation

Monthly investments are compounded using a monthly growth model with support for annual step-up contributions and inflation-aware reporting.

FV = P x [((1 + r)^n - 1) / r] x (1 + r)
SWP withdrawals

The withdrawal phase models corpus growth first and payout second, which better reflects how systematic withdrawals behave over time.

New Corpus = Current Corpus x (1 + Monthly Rate) - Withdrawal
Combined lifecycle planning

The combined planner connects accumulation, retirement income, inflation, and retirement horizon into a single narrative model.

Required SIP is linked to the retirement income target and planning horizon
