Example Retirement Calculation
Let's break down how we estimate a retirement for a 30-year-old planning to retire at 65.
Step 1: Years to Accumulate
Time = 65 (Retire) - 30 (Now) = 35 years.
This is the critical window where compounding does the heavy lifting.
Step 2: Adjusting for Inflation
A $60,000 lifestyle today will cost roughly $142,395 in 35 years (assuming 2.5% inflation).
You must plan for future prices, not today's prices.
With a $25,000 start and $500/month contributions at 7% return, your nest egg grows to approximately $1,100,000.
Frequently Asked Questions
How much income should I replace?
Standard financial guidance suggests aiming to replace 70% to 80% of your pre-retirement gross income. This assumes you will have lower expenses (paid-off mortgage, no commuting costs) but potentially higher healthcare costs.
What rate of return should I assume?
For pre-retirement (accumulation), a diversified portfolio of stocks and bonds typically sees 6% to 8%. For post-retirement, most experts suggest a more conservative 4% to 5% as you shift toward preservation over growth.
What is the 4% Rule?
The 4% rule suggests that you can safely withdraw 4% of your nest egg in the first year of retirement (and adjust for inflation thereafter) with a high probability of the money lasting 30 years. It is a simplified guideline for sustainability.
How does inflation affect me?
Inflation reduces the purchasing power of your money. A 2.5% inflation rate means that in 30 years, you will need roughly twice as much money to buy the same goods and services you buy today. This calculator adjusts your "Desired Income" automatically to reflect this.
What if I retire 5 years earlier?
Retiring earlier has a double negative impact: you have fewer years for your money to grow, and you have to stretch those same savings over a longer retirement period. Even a 5-year difference can require a significantly larger nest egg.
Does this account for taxes?
No, this calculator shows gross figures. Depending on whether your savings are in a traditional 401k (taxed at withdrawal) or a Roth IRA (tax-free), your actual "spendable" income may be lower than the sustainable income shown here.
