Savings Goal Calculator
This savings goal calculator shows exactly how much to save to reach a financial target. Tell it your goal, your timeline, and your interest rate, and it figures out the monthly deposit you need. It is built for anyone planning toward a house down payment, an emergency fund, a vacation, or a child's education.
Three solving modes answer three different questions: how much to save per period (Monthly Deposit), how long until you hit your goal (Time Needed), or how much you will have at the end (Future Value). Every result accounts for compound interest, so you see how your money grows on top of itself over time.
How to Use the Savings Goal Calculator
Choose a calculation mode
Pick Monthly Deposit to find how much to save per period, Time Needed to find how long until you reach your goal, or Future Value to find your total savings after a set period. The mode you choose hides the field it solves for.
Enter your details
Fill in your Savings Goal, Current Savings, Contribution, Annual Interest Rate, and Time Period using the text fields or sliders. Tap a year preset (3, 5, 10, 20, or 30 yr) for a quick timeframe.
Adjust advanced options
Set your Deposit Frequency (weekly, bi-weekly, monthly, or annually) to match your pay cycle, and your Compound Frequency (daily, monthly, quarterly, or annually) to match how interest is added.
Review your results
Results update instantly as you change inputs. Read the summary cards for the key figures, the charts for a visual of your growth, and open the Year-by-Year Breakdown for a detailed projection.
Features
Three Calculation Modes
Solve for the deposit you need, the time it takes, or the future value you will reach. Each mode hides the value it calculates so it is clear what to enter.
Compound Interest Built In
Set an annual interest rate and the calculator factors compound growth into every result, including interest earned on your existing savings.
Flexible Deposit Frequencies
Save weekly, bi-weekly, monthly, or annually. Labels and amounts adjust automatically to match the schedule you choose.
Compounding Options
Choose daily, monthly, quarterly, or annual compounding to compare how the schedule affects your total interest.
Synced Sliders & Inputs
Drag a slider or type an exact number; the two stay in sync. Year presets jump to common timeframes in one tap.
Stacked Growth Chart
A bar chart shows your balance growing year by year, with deposits and interest stacked separately so you can see each contribution.
Savings Breakdown Donut
A donut chart splits your final balance into initial savings, regular deposits, and earned interest at a glance.

Frequently Asked Questions
How much do I need to save each month to reach my goal?
Use Monthly Deposit mode. Enter your savings goal, any current savings, your interest rate, and your timeline, and the calculator shows the exact amount to deposit each period. Switch the deposit frequency to weekly, bi-weekly, or annually and the figure updates to match.
How long will it take to reach my savings goal?
Switch to Time Needed mode and enter how much you can save regularly. The calculator returns the time to reach your goal in years and months. If the goal is unreachable with your settings, it shows a dash instead.
Does this calculator account for interest on savings?
Yes. Enter your annual interest rate and the calculator applies compound interest to both your deposits and your existing balance. Set the rate to 0% to plan a no-interest savings goal where the totals come purely from your deposits.
What is the difference between deposit frequency and compound frequency?
Deposit frequency is how often you add money (weekly, bi-weekly, monthly, or annually). Compound frequency is how often interest is calculated and added to your balance (daily, monthly, quarterly, or annually). They are independent — you might deposit monthly while your account compounds daily.
What if I already have an initial deposit saved?
Enter it in the Current Savings field. The calculator counts it toward your goal and earns interest on it from day one, so the deposit you need or the time required goes down accordingly.
What interest rate should I use?
Use the annual percentage yield offered by your savings account or expected investment return. High-yield savings accounts often pay around 4-5%, while stock market index funds have historically averaged roughly 7-10% per year. For conservative planning, choose a lower rate.
How accurate are the projections?
The calculator uses standard compound interest formulas, so the math is precise for the inputs you give it. Real-world returns vary because interest rates change and investments fluctuate, so treat the results as a planning guide rather than a guarantee.
