// FORMULA

For each month m, compound the running balance:
  Balance ← (Balance + P_m) × (1 + i)
P_m grows by (1 + step%) at the start of every year.

i = annual return / 12. Contributions are treated as start-of-month.

// EXAMPLE

// WORKED OUT

₹10,000/month, 12% return, 10% yearly step-up, 15 years:
  Total invested ≈ ₹38.13 lakh
  Final value     ≈ ₹76 lakh+

// WHAT THIS MEANS

A step-up SIP mirrors how income grows. Because each year's contribution is bigger than the last, but each rupee also has fewer years to compound, the final corpus depends on the balance between rate of return and rate of step-up. The step-up almost always beats a flat SIP if it tracks your income growth.
