Savings Calculator
Clear savings goals are easier to reach when you can see where a monthly deposit takes you. This savings calculator projects your balance from what you have saved so far, a monthly contribution, an annual interest rate and a number of years. Optional interest lets you see how even modest yields add up. Add a savings goal and the calculator also shows how long your current deposit takes to reach it, and the monthly deposit you would need to get there in the years you choose. Use it for emergency funds, travel budgets, down payments and any goal where consistency matters more than complexity.
Shows how long your deposit takes to reach the goal, and the deposit needed in the years above. Leave the years empty if you only want the time.
Please enter valid, non-negative values, and either the years or a savings goal.

How to Use the Savings Calculator
- Enter the amount you have saved so far (leave it empty if you are starting from nothing).
- Enter how much you will add each month and for how many years.
- Add an expected annual interest rate if the money will earn interest.
- Optionally enter a savings goal. Leave the years empty if you only want to know how long the goal takes.
- Calculate to see the final balance, your total contributions and the interest earned, plus the time to reach your goal and the monthly deposit that would reach it in the years you entered.
Savings Calculator Formula Explained
Future Value of Monthly Deposits, and the Reverse for a Goal
Each month the balance earns interest at the yearly rate divided by 12, and then your monthly contribution is added. This repeats for every month of the plan. Your deposit is added at the end of the month, so it starts earning interest the following month. With no interest, the result is simply your starting amount plus all deposits. Even a small annual rate makes a noticeable difference over several years, because each deposit also earns interest. To find the time to reach a goal, the calculator repeats the same monthly step until the balance passes the goal, and checks up to 100 years. To find the deposit needed in the years you entered, it solves the same formula for the deposit: with monthly rate r and n months, deposit = (goal − initial × (1 + r)^n) × r ÷ ((1 + r)^n − 1), or (goal − initial) ÷ n when the rate is 0%.
The result is a projection that uses one fixed rate and one fixed monthly deposit. Real accounts may credit interest daily, quarterly or yearly, change their rates, charge fees or tax the interest, so a real balance can differ. The calculator uses the yearly rate divided by 12 each month, not an effective annual yield. Treat it as an estimate for planning, not as financial advice.
Savings Calculator Example Calculation
Saving toward a €12,000 goal with €2,000 already set aside and €250 monthly deposits at a modest interest rate gets there sooner than a zero-interest path. Missing a month lowers the final balance; catching up later can recover it if cash flow allows.
Worked example: enter 2,000 as initial savings, 250 as the monthly contribution, 3% as the annual rate and 3 years. The final balance is €11,593.24: €11,000.00 contributed (2,000 + 250 × 36) plus €593.24 in interest. At 0% the same plan ends at €11,000.00, so it falls short of a €12,000 goal. Change the time to 4 years and the balance is €14,987.46. Now enter 12,000 as the savings goal with the 3 years. Your deposit reaches it after 38 months (3 years 2 months), when the balance is €12,151.91. At the end of the 3 years you are €406.76 short, and reaching €12,000 in exactly 3 years needs a monthly deposit of €260.81 instead of €250.
When to use this tool

Savings Calculator — FAQs
Should I count emergency funds in the starting balance?
Only the portion you are willing to redirect toward this specific goal. Keep true emergency reserves separate so one setback does not wipe out the goal.
What if I miss a month?
The projection assumes steady deposits. Missing months lowers the final balance; catching up with larger later deposits can recover it if your budget allows.
Is interest compounded monthly?
The calculator treats the annual rate on a monthly equivalent basis for consistency with regular deposits, which matches how many savings products credit interest.
Can I model increasing deposits over time?
Run separate periods with higher amounts, or average a stepped contribution. The core tool assumes a constant monthly deposit for clarity.
How long will it take to reach my savings goal?
Enter the goal, your starting savings, the monthly deposit and the interest rate. The calculator adds interest and your deposit month by month until the balance reaches the goal, and shows the time in years and months. If the goal is not reached within 100 years, it says so.
What monthly deposit do I need to reach a goal by a date?
Enter the goal and the number of years. The calculator shows the monthly deposit that would grow your starting savings to the goal in that time at the rate you entered. If your starting savings alone would already grow to the goal, it shows that no deposit is needed.
Do I have to enter the number of years?
Not if you enter a savings goal. Leave the years empty and the calculator shows your plan in the month the goal is reached. Without a goal, the number of years is required.
