Step 1: Estimate Your Retirement Income Needs
A common rule of thumb is that you'll need 70-80% of your pre-retirement income to maintain your lifestyle in retirement. This accounts for reduced work expenses and potentially lower taxes, while healthcare costs may increase.
Quick Example
If your current income is $80,000/year and you want 80% replacement:
- Desired annual income: $80,000 × 0.80 = $64,000/year
- Retirement savings needed: $64,000 × 25 = $1,600,000
- (The 25x multiplier comes from 1 ÷ 0.04, the inverse of the 4% rule)
Step 2: Account for Social Security
Social Security will likely cover a portion of your retirement income. Check your benefits at ssa.gov to get an estimate. Subtract your expected Social Security from your desired income to find the gap your savings need to fill.
Step 3: Factor in Inflation
$64,000 today won't buy the same things in 20 years. At 2.5% inflation, that $64,000 will need to be about $105,000 in 20 years to have the same purchasing power. This is why inflation-adjusted calculations are critical.
Step 4: Calculate Your Monthly Savings Need
Once you know your target amount, you can calculate how much to save monthly. Consider your:
- Current savings: This amount will grow through compound interest
- Years until retirement: More time means less monthly savings needed
- Expected return: A balanced portfolio might average 6-7% annually

Common Retirement Planning Mistakes
- Starting too late: Waiting until 40 to save means you need 3-4x more monthly than starting at 25
- Underestimating healthcare: A couple retiring at 65 may need $315,000 for healthcare in retirement (Fidelity, 2024)
- Ignoring inflation: Fixed-income retirees lose purchasing power every year
- Counting on inheritance: Don't plan your retirement around money you may or may not receive
