## 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

### How much does a Rs 10,000 SIP grow to in 15 years?

At a 12% expected annual return, a Rs 10,000 monthly SIP for 15 years grows to roughly Rs 50 lakh, of which Rs 18 lakh is what you actually invested. The rest is compounding returns, which is why starting early and staying invested matters more than the exact monthly amount.
