## How this is calculated

A composite SIP planning tool combining a frequency- and step-up-aware maturity projection with optional inflation adjustment, FIFO per-installment post-tax capital gains, a return sensitivity grid, a volatility/Monte Carlo return range, cost of delay, and expense ratio drag.

**Formula:** `balance_y = balance_(y-1) x (1+i)^n + [P x (1+s)^(y-1)] x [((1+i)^n-1)/i] x (1+i), with n instalments/year for the chosen frequency; real value = nominal / (1+inflation)^years; each instalment k taxed on its own gain (amount x (1+i)^periodsRemaining - amount) based on its own holding period`

**Variables:**

- `P`: Instalment amount per period, in INR
- `s`: Annual step-up rate (annual step-up percentage / 100), 0 if step-up is off
- `i`: Period rate of return (annual return rate / instalments-per-year / 100)
- `n`: Instalments per year for the chosen frequency (12 monthly, 4 quarterly, 52 weekly)
- `y`: Year number (1-indexed)

Reference: Core SIP math validated against Groww and ET Money SIP/step-up-SIP calculators; capital gains rules per the FY 2025-26 equity/debt capital gains regime (post-Budget 2024 amendment).

## Assumptions

- Each instalment is invested at the start of its period (annuity-due), and step-up is applied once a year, at the start of the year, not mid-year.
- Inflation, tax, and expense-ratio figures use the rates shown in the inputs, which are editable assumptions, not guarantees.
- Equity-oriented capital gains use the current FY 2025-26 rates (20% STCG under 12 months, 12.5% LTCG at or above 12 months, Rs 1,25,000 LTCG exemption per financial year, no indexation); debt and hybrid funds are taxed entirely at the entered income tax slab rate.
- The Monte Carlo simulation draws each simulated year's return from a normal distribution around the expected return and the selected volatility spread; it is a simplified model, not a guarantee of actual market behaviour.

## Frequently asked questions

### Why is the "real, post-tax" number so much smaller than the headline nominal corpus?

Layering step-up contributions, an expense ratio drag, capital gains tax, and 30 years of 6% inflation onto the same nominal projection shows the gap between what a basic calculator promises and what you would actually be able to spend in today's terms. It is still a large number, just a more honest one.
