How Much Do You Actually Need to Retire?
This free online retirement calculator uses compound growth to project your balance, then applies the 4% withdrawal rule to estimate sustainable monthly income. Here is how to interpret the result: if the calculator shows $1,200,000 at retirement, the 4% rule suggests you can withdraw about $4,000 per month — $48,000 per year — without running out of money over a 30-year retirement.
The 4% rule comes from the 1994 Trinity Study and has held up well historically. However, if you plan to retire at 55 instead of 65, your money needs to last 40+ years, and some planners recommend using 3–3.5% instead. This free retirement calculator shows you the raw balance — you adjust the withdrawal rate based on your timeline. Calculate online as many scenarios as you need at no cost.
Quick Sanity Check
Annual spending × 25 = savings target. Spending $50k/year? Need $1.25M. Spending $80k/year? Need $2M.

Why Inflation Changes Everything
This free retirement calculator shows two numbers: your nominal balance and your inflation-adjusted balance. The difference can be jarring. At 3% inflation over 35 years, $1,000,000 in future dollars is worth only about $355,000 in today's purchasing power. That "millionaire" retirement may support a middle-class lifestyle, not a wealthy one.
This is why most retirement planners recommend investing in assets that historically outpace inflation — stock index funds, real estate, TIPS bonds — rather than holding cash or low-yield savings accounts. Keeping $200,000 in a savings account earning 0.5% while inflation runs at 3% means your real wealth shrinks by 2.5% per year.
The Social Security Administration adjusts benefits for inflation via COLA (Cost of Living Adjustments) annually. Your personal portfolio needs the same protection — and that requires the online retirement calculator input "annual return" to exceed your expected inflation rate by a meaningful margin, typically 4–5 percentage points.

4 Retirement Planning Moves That Actually Move the Needle
Always Capture the Full Employer Match
A 50% employer match on your 401(k) contributions up to 6% of salary is an instant 50% return — better than any investment you'll find. If your salary is $70,000, maxing the match means getting $2,100 free per year. That alone compounds to over $200,000 over a 30-year career at 7%.
Increase Contributions After Every Raise
Automate a 1% contribution increase each year. Going from 6% to 7% of a $65,000 salary is just $54/month extra — but over 25 years at 7%, that incremental $54 becomes $45,000 more at retirement. You never miss money you never saw in your paycheck.
Consider Delaying Social Security
Each year you delay Social Security past 62 increases your benefit by roughly 6–8% — permanently. Claiming at 70 instead of 62 can increase monthly benefits by 76%. If you can bridge the gap with savings, waiting is often the highest-return "investment" available to retirees. Run the retirement calculator to see if your savings can support a delay.
Keep Asset Allocation Aggressive Early
A 30-year-old with 35 years until retirement can hold 90% stocks — short-term volatility is irrelevant over that horizon. The common rule is "110 minus your age" in stocks. Moving to 50% stocks at age 35 out of fear is one of the most common retirement planning mistakes. Use the retirement calculator to see how a 5% vs 7% return affects your final balance.
