How this calculation works

The initial corpus is invested today. Each month the opening balance grows, then that month’s contribution is added. Monthly growth is calculated as (1 + annual growth rate)1/12 − 1 so it matches the effective annual rate you select.

The monthly contribution increases by the step-up percentage at the start of each new contribution year. After the contribution period, no new money is added; the existing corpus continues to grow until the end of the total stay-invested period. All amounts are nominal future rupees. Tax, fees and inflation are not deducted.

This is an illustration using a constant growth rate, not an assured investment return. “Interest” represents modeled investment growth and does not imply a guaranteed interest-paying product.
