Savings Calculator
Enter current savings, monthly contributions, expected return, and a target amount to project your balance and goal progress over time.
Savings Calculator
Enter your current savings, monthly contribution, expected return, time horizon, and target amount to see a projected balance and goal progress on one screen.
- Current savings are treated as money you already have at the start, so they enter the monthly compounding right away.
- Monthly contributions are assumed to step up each year by the annual contribution growth rate you enter.
- Inflation is only used to restate the ending balance in today’s dollars. Taxes and fees are not included.
- The large number at the top is the projected ending balance after combining current savings and future contributions.
- Goal progress shows how close the current plan gets you to the target amount.
- Required monthly contribution shows what starting contribution would be needed to hit the target under the same assumptions.
- Scenario comparison helps you see how much the outcome changes when returns come in lower or higher.
Enter your assumptions and calculate to see the projected balance, goal progress, and year-by-year path together.
After you calculate, a donut chart shows how much of the ending balance comes from current savings, future contributions, and projected interest.
After you calculate, a line chart shows the year-by-year balance and principal path.
| Year | Monthly contribution | Annual contributions | Annual interest | Cumulative principal | End-of-year balance | Goal progress |
|---|---|---|---|---|---|---|

What is a Savings Calculator?
This tool combines what you already have, what you plan to contribute each month, an expected return, and a target amount to estimate how much you could build over time. Instead of focusing only on product-level maturity interest, it helps you review the full savings path from today to the target.
- It combines current savings with recurring monthly contributions.
- It shows both goal progress and the monthly contribution needed to reach the goal.
- It also includes a today’s-dollar view after inflation for planning reference.
When is it useful?
This is useful when you are building toward a target over several years, such as an emergency fund, a home down payment, education costs, or a wedding budget. It helps you see how far your current savings go, whether the monthly contribution looks realistic, and how much room is left before the deadline. If your goal is tied to home buying, the Mortgage Calculator is a natural next step.
- Emergency fund planning
- Home down payment or moving fund planning
- Education or study-abroad savings goals
- Comparing the effect of raising contributions over time
Key features
Instead of returning just one number, the tool shows the projected ending balance, total principal saved, projected interest, value in today’s dollars, and goal progress on one screen. It also compares a lower-return and higher-return scenario so you can see how sensitive the plan is to small changes.
- Projected balance and total principal summary
- Goal progress, amount still needed, and required monthly contribution
- Conservative / base / higher-return scenario comparison
- Donut chart and year-by-year growth chart
- Year-by-year table with Excel download
How to use it
Start with your current savings and planned monthly contribution, then choose a time horizon and expected return. If you also enter a target amount, you can see whether the current plan is enough or how large the starting monthly contribution may need to be.
- Enter current savings and the monthly contribution you want to plan around.
- Set the savings horizon, annual return, annual contribution growth, and inflation.
- Add a target amount if you are saving toward a specific goal.
- Choose whether each contribution is added at the start or end of the month.
- Calculate to review the projected balance, goal progress, and year-by-year changes.
How the calculation works
This calculator assumes monthly compounding. Current savings start earning right away, and each monthly contribution is added either at the start or end of the month based on your choice. If you want to compare cash saving with long-term investing, the Mutual Fund Calculator and 401k Calculator are useful follow-up tools.
- Projected savings balance: current savings + total contributions + projected interest
- Total principal saved: current savings plus all future contributions
- Projected interest: the growth produced by the return assumption
- Value in today’s dollars: the ending balance restated after inflation
- Required monthly contribution: the starting contribution needed to reach the target under the same assumptions
Frequently asked questions
How is this different from a simple savings-interest calculator?
This tool is built to review a full savings plan by combining current savings with future monthly contributions. A simple savings-interest calculator is better when you want the maturity value of a specific banking product under that product’s rules.
Does it include taxes and fees?
No. This is a general planning tool, so it does not include account-specific taxes, fees, promotional rates, or early-withdrawal terms.
Why is the inflation-adjusted value lower than the ending balance?
Inflation reflects the idea that the same amount of money tends to buy less over time. Because of that, longer plans can show a lower value in today’s dollars than the raw ending balance.
How should I use the required monthly contribution?
It shows what starting monthly contribution would be needed to reach the target under the same timing and return assumptions. If that number is much higher than what you can save now, it may be a sign to extend the timeline or adjust the goal.
Does month-start vs. month-end saving make a big difference?
It can. Saving at the start of each month gives each contribution one more month to compound, so the ending balance can come out a bit higher, especially on longer plans or with larger contributions.
