Retirement Planning Calculators
Retirement calculators can be genuinely useful tools — and they can also give you a false sense of precision. A calculator that tells you your $400,000 savings will last exactly 23 years at a 5% return is technically an answer, but it’s an answer built on assumptions that may or may not match reality.
We offer calculators as starting points, not final answers. They help you see the ballpark — how much you might need, whether your current savings rate puts you on track, what impact delaying Social Security has on your lifetime income. For more nuanced analysis, those numbers need to be tested against real-world variables.
Useful Calculations to Run
A Social Security claiming calculator is one of the most valuable tools available. Social Security estimates vary dramatically depending on when you file — from age 62 all the way to 70. The difference can exceed $500 per month permanently. Running those numbers before making your election is essential.
A withdrawal rate calculator helps you understand how long your savings might last under different spending scenarios. The traditional “4% rule” has been questioned in recent years given current market conditions and longer life expectancies — a calculator that lets you model different rates is more useful than a rule of thumb.
The Limit of Calculators
What calculators can’t account for: your actual health trajectory, major unexpected expenses (like a long-term care event), changes in tax law, or the emotional reality of managing money in a volatile market. They’re useful inputs, not complete plans.
