It can be hard to know exactly how much you’ll need to save for retirement. Factors such as your savings rate, how the stock market is performing, compounding investment returns over time, and whether you decide to take an early withdrawal, can all affect the progress of your nest egg.
If you’re working with a financial planner, their expertise will help you understand how multiple variables can affect your situation. If you’re not, the right retirement calculator can help you figure things out. Below are some details on how to find the right retirement calculator for you and how to understand the difference between some of the available options.
Where to find retirement calculators
One of the easiest places to find a retirement calculator is online. There’s no shortage of websites, typically from brokerage services, personal finance publications, and financial planners, that offer a tool for you to use. Keep in mind, many of these services offer their calculator as a sales tool, hoping to ultimately engage users as their customers.
What to look for in a retirement calculator


Retirement calculators each perform the same general function and there are features that all good versions have. They should have a place for you to input the amount you plan to spend in retirement and either your age or the date at which you’d like to stop working. You should also have a way to input any additional amounts that you plan to contribute to your savings and be able to add in the amount for benefit payments that sources such as social security will contribute.
Additionally, a good calculator should account for a conservative and compounded rate of investment returns that can be adjusted for various levels of risk and it should include a calculation for a moderate rate for inflation. Lastly, each of these settings should be able to be adjusted so you can see what things look like if you want to change your retirement date, add savings at a faster rate, etc.
