What is Retirement Savings?

Retirement savings is the total amount of money you set aside and invest during your working years to support yourself financially after you stop working. It's a crucial part of personal finance, helping you maintain your lifestyle and cover expenses when you no longer have a regular paycheck. Most people use retirement savings to fund living costs, healthcare, travel, and more in their later years.

How is Retirement Savings Calculated? (Formula Explained)

The calculator uses the future value of a series formula, adjusted for inflation:

FV = PV × (1 + r)n + PMT × [((1 + r)n - 1) / r]
Annual Withdrawal = FV × Withdrawal Rate
  • FV: Future value of your retirement savings
  • PV: Current savings (present value)
  • PMT: Annual contribution
  • r: Real annual return (after inflation)
  • n: Years until retirement

The calculator also estimates how long your savings will last based on your withdrawal rate and investment growth after retirement.

Example: Retirement Savings Calculation Step-by-Step

Let's say Alex is 35 years old, plans to retire at 67, has $25,000 saved, contributes $6,000 per year, expects a 7% annual return, 2.5% inflation, and wants a 4% withdrawal rate:

  • Years to retirement: 32
  • Real return: (1 + 0.07) / (1 + 0.025) - 1 ≈ 4.39%
  • Future value: FV = 25,000 × (1.0439)32 + 6,000 × [((1.0439)32 - 1) / 0.0439] ≈ $627,000
  • Annual withdrawal: $627,000 × 0.04 = $25,080

Alex's estimated retirement savings is $627,000, supporting annual withdrawals of $25,080 (in today's dollars).
