Inputs Explained in Simple Terms
Opening Deposit
This is the amount you start with when opening your savings account. It forms the foundation of your savings growth.
Monthly Savings
This represents how much money you add to your account every month. Even modest monthly deposits can significantly boost total savings over time.
Annual Interest Rate
This is the yearly interest rate applied to your savings. Higher rates lead to greater interest earnings.
Time Period (Years)
This defines how long you plan to keep saving. Longer time frames allow compound interest to work more effectively.
Compounding Frequency
Compounding determines how often interest is added to your balance. Options include daily, monthly, quarterly, or annually. More frequent compounding generally results in higher total savings.

Using the calculator is straightforward:
- Enter your opening deposit amount
- Add your monthly savings contribution

Example Savings Calculation
Consider the following example:
- Opening Deposit: $2,000
- Monthly Savings: $250
- Annual Interest Rate: 3.75%
- Time Period: 10 years
- Compounding: Monthly
After calculation, the tool will display:
- Total Principal: Your opening deposit plus all monthly savings
- Total Interest: The amount earned from interest alone
- Total Savings: Your final account balance
- Effective APY: The true annual yield based on compounding
- Average Monthly Growth: How much your savings grow per month on average
This breakdown makes it easy to see how time, consistency, and compounding impact your savings.
Understanding Effective APY
Effective APY shows the real return you earn after accounting for compounding frequency. Even if two accounts offer the same interest rate, the one with more frequent compounding will usually have a higher effective APY.
This calculator automatically calculates the effective APY so you can better understand the true earning potential of your savings account.
Benefits of Comparing Compounding Options
One of the most powerful features of this calculator is the ability to compare compounding frequencies. By switching between daily, monthly, quarterly, and annual compounding, you can see how much difference compounding makes over time.
This insight helps you choose savings accounts more wisely and maximize returns without taking additional risk.
