Retirement Calculator

How to Use This Retirement Calculator

This retirement calculator helps you project how much you will have saved by your target retirement age. It accounts for investment growth, monthly contributions, and the impact of inflation on your purchasing power.

Step 1: Enter your age and retirement target. Provide your current age and the age at which you plan to retire. The calculator determines the number of years your investments have to grow. Most people target age 65, but early retirement at 55 or delayed retirement at 70 are also common choices.

Step 2: Enter your savings and contributions. Input your current retirement savings across all accounts, including 401(k), IRA, and taxable investment accounts. Then set the amount you plan to contribute each month. Be realistic about what you can consistently invest over the long term.

Step 3: Adjust return and inflation assumptions. Set your expected annual investment return and inflation rate. The calculator shows both nominal projections and inflation-adjusted values, plus your estimated monthly retirement income based on the 4% withdrawal rule.

How Retirement Projections Are Calculated

Your projected retirement savings are calculated by compounding your current balance forward at the expected annual return rate while adding monthly contributions each year. The formula repeatedly applies growth and adds contributions for each year until you reach your retirement age.

The inflation-adjusted projection uses the real rate of return, which is the nominal return minus the inflation rate. This shows what your future savings will be worth in terms of today's purchasing power. It is essential for realistic retirement planning because a million dollars in 30 years will not buy as much as a million dollars today.

Monthly retirement income is estimated using the 4% rule. This guideline, based on historical market data, suggests that withdrawing 4% of your portfolio in the first year of retirement and adjusting for inflation each subsequent year provides a high probability of your savings lasting at least 30 years.

Tips for Successful Retirement Planning

1. Max out employer matching. If your employer matches 401(k) contributions, contribute at least enough to get the full match. This is an immediate 100% return on your investment and is the single most impactful step you can take to boost your retirement savings.
2. Increase contributions with every raise. When your salary increases, direct at least half of the raise toward retirement savings. This allows you to build wealth without feeling a lifestyle impact. Over time, these incremental increases compound into significantly higher retirement balances.
3. Diversify across account types. Use a mix of traditional 401(k) or IRA accounts for tax-deferred growth and Roth accounts for tax-free withdrawals in retirement. This gives you flexibility to manage your tax bracket when you start drawing income in retirement.
4. Plan for healthcare costs. Healthcare is one of the largest expenses in retirement. Consider contributing to a Health Savings Account (HSA) if eligible, as it offers triple tax benefits and can be used for medical expenses in retirement. Factor healthcare costs into your retirement budget.
5. Revisit your plan annually. Life circumstances, income, and market conditions change. Review your retirement plan at least once per year to ensure you are on track. Adjust contributions, asset allocation, and retirement age as needed to stay aligned with your financial goals.
