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 About $548,171.30 projected, with a $451,828.70 gap to a $1,000,000 target.
- $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. For the starter example, $25,000 plus $500 each month at a 7% annual return for 25 years projects about $548,171.30. The calculator shows $175,000.00 of contributions, about $373,171.30 of estimated growth, and a $451,828.70 target gap.
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?
Current savings means the retirement money already saved before this projection starts. Monthly contribution means the amount added at the end of each month in this simple model. Estimated return means the annual growth assumption. It is not guaranteed and real markets can lose money. Years to grow means how long the projection runs before comparing the balance with the target. Target amount means the savings goal used to show whether the projection is above target or still has a gap.
How does the Retirement Calculator handle monthly contributions?
It converts the annual return assumption into monthly growth, compounds the current savings, then adds each monthly contribution at the end of the month. That timing makes the answer a planning estimate, not an account statement.
Does this include inflation or withdrawals?
No. The projection shows a future balance from savings going in. It does not reduce the result for inflation, retirement spending, withdrawals, required minimum distributions, taxes, or account fees.
What does the target gap mean?
The target gap is the target amount minus the projected balance. A gap does not mean the plan failed; it means the entered savings, contribution, return, and time assumptions do not reach that target in this simplified model.
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. For the starter example, $25,000 plus $500 each month at a 7% annual return for 25 years projects about $548,171.30. The calculator shows $175,000.00 of contributions, about $373,171.30 of estimated growth, and a $451,828.70 target gap.
How should I read the Retirement Calculator answer?
Start with projected retirement savings, then compare total contributions with estimated growth. The target gap or above-target line explains how far the projection is from the goal you entered.
