Retirement Calculator

Estimate how much you need to retire comfortably with our easy-to-use retirement calculator.

Plan Your Future with Our Free Retirement Calculator

Proper retirement planning is essential to secure your financial future. Our free retirement calculator helps you estimate how much money you’ll need to retire comfortably. Whether you’re asking “how much do I need to retire?” or looking for a detailed retirement savings calculator that considers compound interest, monthly contributions, and more — you’re in the right place.

How Does the Retirement Calculator Work?

Our calculator uses the future value of a series formula, which considers:

  • Current savings – your starting point.
  • Monthly contributions – regular amounts you add.
  • Expected annual return – how much your investments grow each year.
  • Years to retirement – how long your money compounds.

The formula is essentially:

FV = P * (1 + r)^n + PMT * [((1 + r)^n - 1) / r]

Where:
P = current savings
PMT = monthly contribution
r = monthly return rate
n = total months

Why Use a Retirement Calculator?

This tool can help you:

  • Figure out how much you need to save for retirement.
  • See the power of compound interest on long-term investments.
  • Plan contributions to your 401(k), IRA, or other retirement accounts.
  • Adjust assumptions to see how returns impact your future.

Practical Example

Suppose you are 30 years old, have $10,000 saved, plan to contribute $500 per month, expect a 6% annual return, and aim to retire at 65. The calculator estimates you'll have approximately $762,000 by retirement. Adjust contributions or return rates to see different outcomes.
