Quick start
- Open the Retirement Calculator.
- Enter current retirement savings and monthly contribution.
- Use the first example, "Early saver: $25,000 saved, $500/month, 7%, 25 years", if you want to see a filled-out estimate before entering your own values.
- Calculate, read the formula line, then copy the result only after the amounts, percentages, time periods, or assumptions look right.
Best uses
Start here if one of these sounds like your job. The examples below show which inputs matter most.
- Project a retirement savings balance over time.
- Compare contribution amounts and estimated returns.
- Check the gap between projected balance and a target number.
- Use a consistent planning estimate while adjusting assumptions.
What this calculator is for
The Retirement Calculator projects a future savings balance and compares it with a target. It is designed for scenario planning, not for deciding exactly how much you need.
Good fit examples: Project a retirement savings balance over time. Compare contribution amounts and estimated returns.
What to enter
Finance estimates are sensitive to small input changes. Check whether a field expects a monthly amount, annual amount, dollar value, or percent before calculating.
- Enter current retirement savings and monthly contribution.
- Use an estimated annual return, understanding that real markets vary.
- Enter years until retirement and an optional target amount.
Example walkthrough
Try the calculator example: Early saver: $25,000 saved, $500/month, 7%, 25 years. The example result is Projected retirement balance.
- $25,000 saved plus $500/month for 25 years at 7% compounds into a projected future balance.
- The calculator also shows how much came from contributions versus estimated growth.
Formula and steps
In plain language: The calculator compounds current savings and monthly contributions at an estimated annual return, then compares the future value with your target amount. If the result seems too high or too low, first check whether each field expects a monthly amount, annual amount, dollar value, or percent.
If the estimate looks surprising, check the formula and inputs before using the answer in a budget, comparison, or planning note.
How to read the answer
Start with the headline result. Then read the supporting lines to see what made the number larger or smaller, such as rates, time periods, costs, taxes, fees, discounts, or contributions.
- Ending balance is a projection based on the assumptions you entered.
- Goal gap shows how far the projection is above or below the target.
- The result is before taxes, fees, inflation, withdrawals, and market changes.
Common mistakes to avoid
Most bad finance estimates come from mixing rates, terms, monthly amounts, and annual amounts. The other common mistake is using a planning estimate as if it were a final quote.
- Do not treat one return assumption as a promise.
- Do not ignore inflation when thinking about future spending power.
- Do not use this as a substitute for personalized retirement planning.

FAQ in plain language
When should I use the Retirement Calculator?
Use it when you want to test the exact inputs on this page: Project a retirement savings balance over time. Compare contribution amounts and estimated returns. The result is a check against your assumptions, not proof that a lender, tax app, broker, platform, or provider will use the same number.
What do the main Retirement Calculator inputs mean?
Money tools are picky about labels. Dollar fields should be entered as dollar amounts, rate fields should be entered as percentages like 6.5 instead of 0.065, and term fields should match the page label such as months or years. If a field says monthly, do not enter a yearly total unless the tool specifically asks for it.
What is the Retirement Calculator doing with my numbers?
In plain language: The calculator compounds current savings and monthly contributions at an estimated annual return, then compares the future value with your target amount. If the result seems too high or too low, first check whether each field expects a monthly amount, annual amount, dollar value, or percent.
How should I read the Retirement Calculator answer?
Start with the headline number, then use the supporting lines to see why the answer moved. For finance calculators, the extra lines often explain interest, tax, fees, principal, payment timing, or totals paid over time. Those pieces matter because two results can look close at first but cost very different amounts later.
What does this estimate leave out?
This is a long-term projection, not retirement advice. It does not include taxes, account rules, contribution limits, market volatility, inflation, benefits, or withdrawal planning. Real finance decisions can also depend on fees, timing, local rules, credit details, and provider-specific terms.
What should I double-check before copying the result?
Check the rate, time period, compounding or payment frequency, and whether the value is before tax or after tax. A common mistake is mixing monthly and yearly numbers, which can make a finance answer look believable even when it is off by a lot.
Does the site save my finance inputs?
No. The calculator runs in your browser tab. Recent answers stay only on the page while you use it, and they are not sent to a server.
