Retirement Calculator
Plan your retirement with our comprehensive calculator. Estimate savings growth, retirement income needs, and check if you are on track.
Planning for retirement is about building the financial independence to maintain your lifestyle after you stop working. The earlier you start and the more consistently you save, the greater the power of compound growth working in your favor. This calculator projects your savings trajectory through both the accumulation and withdrawal phases so you can assess whether you are on track for a secure retirement.

Key Terms
- The 4% Rule
- A retirement withdrawal guideline suggesting you can safely withdraw 4% of your portfolio in the first year of retirement, adjusting for inflation each subsequent year, with a high probability of your savings lasting 30 years.
- Sequence of Returns Risk
- The danger that poor investment returns early in retirement will deplete a portfolio faster than expected, even if long-term average returns are adequate. The order of returns matters as much as the average.
- Required Minimum Distributions (RMDs)
- Mandatory annual withdrawals from tax-deferred retirement accounts (traditional IRA, 401(k)) that must begin at age 73 (as of 2023). Failure to take RMDs results in a 25% excise tax on the amount not withdrawn.
- Tax-Deferred vs Tax-Free Accounts
- Tax-deferred accounts (traditional IRA, 401(k)) delay taxes until withdrawal. Tax-free accounts (Roth IRA, Roth 401(k)) are funded with after-tax dollars and qualified withdrawals are entirely tax-free, including all growth.
- Income Replacement Rate
- The percentage of pre-retirement income needed to maintain your standard of living in retirement. Most financial planners recommend 70-80%, as some expenses (commuting, payroll taxes, retirement savings) decrease.
- Safe Withdrawal Rate
- The maximum annual percentage of a retirement portfolio that can be withdrawn while minimizing the risk of running out of money. The 4% rule is the most commonly cited safe withdrawal rate.

Quick Tips
- •Maximize your employer match -- it is essentially free money and an immediate 100% return on that portion of your contribution.
- •Increase your savings rate by 1% each year; small incremental raises are painless but compound significantly over decades.
- •Consider a Roth conversion ladder if you plan to retire early, allowing tax-free withdrawals after a 5-year seasoning period.
- •Build a 2-3 year cash reserve before retirement to avoid selling investments during a market downturn (sequence of returns risk).
- •Review and adjust your retirement plan annually to account for salary changes, market performance, and evolving goals.

How to Use This Calculator
Enter your current age, existing retirement savings, and goals (target retirement age and desired income). Optionally adjust expected returns and inflation. Click Calculate to see whether you are on track and how long your savings may last in retirement.
Understanding the Formula
Uses annual compounding for growth and inflation adjustments. Shortfall is calculated if portfolio reaches zero before life expectancy.
Examples
Retiring at 65 with $1.2M Saved
You are 35 with $150,000 saved and contribute $1,500/month. Assuming 7% growth before retirement and 5% after, with 3% inflation, you accumulate about $1,200,000 by age 65. Withdrawing $48,000/year (4% rule), your portfolio lasts through age 92 before running out.
Early Retirement at 55 with Aggressive Savings
You are 30 with $50,000 saved, contributing $3,000/month at 8% annual growth. By 55, you accumulate roughly $2,450,000. Needing $70,000/year in today's dollars (adjusted for inflation), your portfolio sustains withdrawals through age 90, giving you 35 years of retirement income.
Late Start at 45 with Catch-Up Contributions
You are 45 with $100,000 saved, earning $95,000/year. By maxing out 401(k) contributions at $23,500/year (plus $7,500 catch-up after 50) with a 3% employer match and 7% returns, you accumulate approximately $950,000 by age 65. Combined with $2,200/month in Social Security, your portfolio can sustain withdrawals through age 88.
Frequently Asked Questions
What is the 4% rule?
It states that you can withdraw 4% of your portfolio in the first year of retirement (adjusted for inflation thereafter) with a high probability of not running out of money for 30 years.
How much should I save?
A common goal is to save 15% of your gross income, including employer matches.
What is income replacement rate?
Most retirees need 70-80% of their pre-retirement income to maintain their standard of living, as savings expenses stop and taxes may decrease.
When should I start claiming Social Security?
You can claim as early as 62 at a reduced benefit, at full retirement age (66-67) for the standard benefit, or delay until 70 for an 8% annual increase. Delaying is generally advantageous if you are healthy and have other income sources to bridge the gap.
What is sequence of returns risk?
Poor market returns in the first few years of retirement can permanently damage your portfolio, even if long-term averages are good. A 30% drop right after you retire forces you to sell more shares at low prices, leaving fewer shares to recover. This is why a cash buffer and conservative early withdrawals are important.
Should I use a traditional or Roth retirement account?
Traditional accounts give a tax deduction now but are taxed on withdrawal. Roth accounts are funded with after-tax dollars but grow and are withdrawn tax-free. If you expect to be in a higher tax bracket in retirement, Roth is often better; otherwise, traditional may save you more.
Assumptions & Limitations
- Assumes a constant annual rate of return throughout both the accumulation and withdrawal phases.
- Does not account for Social Security benefit adjustments beyond basic COLA inflation.
- Assumes a fixed inflation rate applied uniformly each year.
- Employer match is calculated as a flat percentage of salary and does not model vesting schedules.
- Pension income is assumed to remain flat (not inflation-adjusted), reflecting common private-sector plans.
