Compare two college savings targets

Model compound growth · Fictional case

The situation

A family starts with ₹4 lakh. Assume 8% annual growth for six years and no interim cash flows.

Your task

Will the balance reach ₹6.5 lakh?

Reveal step-by-step solution
  1. Set up the problem

    Apply six growth periods to the opening balance.

  2. Work through the numbers

    Future value = ₹4 lakh × 1.08⁶ ≈ ₹6.35 lakh. Required initial balance = ₹6.5 lakh ÷ 1.08⁶ ≈ ₹4.10 lakh.

  3. Interpret the result

    The forecast falls short by about ₹15,250 at year six. The growth rate is an exercise assumption.

What to remember

Count compounding periods and distinguish a year-six shortfall from a deposit needed today.
