Disclaimer
This is an independent, fan-created retirement calculator and is not affiliated with NerdWallet. It uses general retirement planning formulas and assumptions commonly found in NerdWallet-style financial calculators for educational and illustrative purposes.
It is for educational and planning purposes only. We provides a simplified projection based on the assumptions you enter, including contribution amounts, investment returns, inflation, salary growth, retirement age, and life expectancy.
Results are not a promise, guarantee, or prediction. Actual retirement outcomes can differ materially because of market volatility, sequence-of-returns risk, taxes, penalties, employer plan rules, changes in contribution behavior, healthcare costs, Social Security timing, pension rules, and other personal or economic factors.
About This Retirement Calculator
This retirement calculator can help you estimate whether your current savings plan is on track for the future you want.
Unlike basic savings calculators, this tool separates retirement planning into two stages:
- Saving for retirement and
- Spending during retirement.
To make those estimates, the calculator factors in:
- Current retirement savings
- Monthly contributions
- Investment growth
- Inflation
- Retirement spending
- Other retirement income.
How To Use This Retirement Calculator
This calculator works best when you use realistic assumptions based on your current finances and future retirement goals.
Step 1: Enter Your Current Age
Your current age determines how many years you have left to save before retirement.
I would recommend adding a longer time horizon, as it gives your investments more time to benefit from compound growth.
Step 2: Add Your Annual Income
Enter your current yearly income before taxes.
The calculator uses this number to estimate how your retirement contributions may grow if your income increases over time.
As your income grows, you may be able to increase retirement contributions over time.
Step 3: Enter Your Current Retirement Savings
Add the total amount you’ve already saved for retirement.
This may include balances from accounts such as:
- 401(k)
- IRA
- Pension plans
- Brokerage accounts
- Employer-sponsored retirement plans
Your current balance becomes the starting point for future growth projections.
Step 4: Add Monthly Contributions
Enter how much you contribute toward retirement each month.
Regular contributions are one of the biggest drivers of long-term retirement growth.
Even small contribution increases over time can make a meaningful difference over several decades.
Step 5: Estimate Your Retirement Expenses
Enter your expected monthly spending during retirement.
This may include costs such as:
- Housing
- Food
- Transportation
- Healthcare
- Insurance
- Travel
- Entertainment
Many financial planners estimate retirees may need roughly 55% to 80% of their pre-retirement income, though actual spending varies by lifestyle and health needs.
Step 6: Add Other Retirement Income
If you expect income outside your retirement savings, enter the monthly amount here.
- Social Security
- Pension income
- Rental income
- Part-time work
- Annuities
The calculator subtracts this income from the amount you may need to withdraw from retirement savings each month.
This can help provide a more realistic estimate of how long your retirement portfolio may last.
