What the result means

The future value is an estimate based on the expected return. It includes both your invested amount and the wealth gain from compounding. Actual returns depend on market performance.

How to use this calculator

  1. 1Enter your monthly investment amount.
  2. 2Enter the expected annual return rate.
  3. 3Enter the number of years you plan to invest.
  4. 4Press Calculate to see your estimated future value.

The formula

The calculation uses a standard, verifiable formula. Here it is in its simplest form.

Future Value = P × ((1 + r)ⁿ − 1) / r × (1 + r) Where: P = Monthly investment r = Monthly return rate (annual ÷ 12 ÷ 100) n = Number of months

What each variable means

SymbolNameDescription
PMonthly investmentThe amount you invest each month.
rMonthly returnExpected annual return divided by 12 and 100.
nMonthsTotal number of monthly investments.

Step-by-step example

Example: ₹5,000/month at 12% for 10 years

Monthly investment:₹5,000Expected return:12%Period:10 years
  1. 1Monthly rate = 12% / 12 = 1% = 0.01
  2. 2Months = 10 × 12 = 120
  3. 3Future value = 5,000 × ((1.01)¹²⁰ − 1) / 0.01 × 1.01
  4. 4(1.01)¹²⁰ ≈ 3.3004
  5. 5Future value ≈ 5,000 × 2.3004 / 0.01 × 1.01 ≈ ₹11,61,695
  6. 6Total invested = ₹5,000 × 120 = ₹6,00,000
  7. 7Wealth gain = ₹11,61,695 − ₹6,00,000 = ₹5,61,695

Result

Future value ≈ ₹11,61,695

What changes the result

  • Higher monthly investments increase the future value proportionally.
  • Higher expected returns significantly increase wealth gain.
  • Longer investment periods allow more time for compounding.
  • Starting early has a dramatic impact due to compound interest.

Edge cases to be aware of

Unusual situations handled correctly

  • Zero return: future value equals total invested.
  • Very long periods can produce large future values due to compounding.
  • Returns are not guaranteed - this is an estimate, not a promise.

Common mistakes

Avoid these errors

  • Using annual return directly instead of dividing by 12.
  • Confusing total invested with future value.
  • Assuming guaranteed returns - markets fluctuate.

Assumptions

  • Equal monthly investments throughout the period.
  • Constant rate of return (compounded monthly).
  • No withdrawals during the investment period.

Limitations

  • Actual returns vary with market conditions.
  • Does not account for taxes or fund expenses.
  • Past performance does not guarantee future results.
