Savings Calculator

With our savings growth calculator, you can set a starting balance and a contribution frequency, estimate your goal time frame and discover how much you need to save each month.

How to Calculate Your Savings Growth

  • Starting Savings Balance: This is the initial sum you've already accumulated towards your total savings goal. It serves as the foundation of your future savings.
  • Annual Percentage Yield (APY): the amount of interest your savings will earn over time, expressed as a yearly percentage.
  • Contribution Frequency & Amount: Specify how often (monthly, semi-monthly or annually) you plan to add to your savings and the designated amount for each contribution.
  • Timeframe (Year/Month): Input the number of years or months you'd like to reach your savings objective. For example, setting a goal of saving $1,000 in one year.

How Does a Certificate of Deposit Work?

With a Certificate of Deposit (CD), you deposit a set amount of money for a fixed length of time, often six months to five years. Essentially, you're entering into an agreement to leave your funds untouched for the chosen period of time.

In exchange, the bank offers you a fixed interest rate return, which typically exceeds the rate you'd get from a regular savings account. CDs can also be beneficial for other reasons, including:

  • Predictable Growth: The fixed interest rate on a CD ensures you receive a predetermined level of return on investment.
  • Higher Earning Potential: CDs often boast higher interest rates than standard savings accounts.
  • Multiple Terms: CDs offer short and long-term options, so they can be customized to fit your financial needs.

Certificates of Deposit are a valuable asset for those seeking to capitalize on higher interest rates while keeping your initial investment safe. CDs also offer automatic renewals if you'd like to continue earning interest on your money.

However, keep in mind that CDs do have early withdrawal penalties, so make sure you will not need the money before your fixed term is over.

Transferring funds from your CD to another account is also not possible, so be sure to choose an accessible bank for your investment.

How Does a Savings Account Work?

Savings accounts provide a safe space for your money. Unlike investment accounts, you can easily deposit extra money and take it out when you need it. 

You start with an initial deposit. The bank pays you an interest rate on your balance over time, typically calculated based on the average daily balance maintained in the account. As your money sits in the account, your savings passively increase.

In the unlikely event of a bank failure, the Federal Deposit Insurance Corporation (FDIC) insures you up to $250,000 per account


How to Start Growing Your Savings


Building a secure financial future starts with a solid savings plan. This can include cutting back on spending, opening a savings account or investing in a CD.

Here are some impactful savings platforms you can take advantage of.

Savings Account

Savings accounts offer a safe and accessible place to keep your extra funds. Even small, regular deposits add up significantly over time.

They're ideal for building an emergency fund since the process of building one doesn't require a large cash deposit upfront.

They are also optimum for saving for short or medium-term goals, such as a vacation or a down payment on a car.

Certificate of Deposits (CDs)

Unlike other savings methods, CDs offer a chance to potentially grow your money faster with fixed, higher interest rates for short or longer-term periods.

However, your money is locked away for the term length you choose, which can range from a few months to multiple years.

Early withdrawals can incur a penalty. Therefore, CDs are best suited for financial goals you know you won't need to reach immediately.

Money Market Accounts

Money market accounts are essentially savings accounts that pay slightly higher interest rates while allowing you to make a few transactions each month.

It bridges the gap between a traditional savings account and a checking account, offering additional interest on your balance over traditional savings accounts and access to your funds when needed.

By utilizing the Savings Growth Calculator, you can compare options and determine the best fit for your savings plan. The key is to start saving today.

How Do I Calculate Interest on a Savings Account?

Savings account interest is typically calculated based on a method known as the daily balance method. The daily balance method calculation factors are broken down as follows:

  • Tracking Your Balance: Each day, the bank tracks your account balance.
  • Calculating the Average: For each day in the interest-earning period, the bank multiplies your daily balance by the daily interest rate (in decimal format). This daily interest amount is calculated independently for each day.
  • Interest Rate Application: At the end of the interest-earning period, the bank adds up all the daily interest amounts to get the total interest earned for that period.
  • Adding Interest: Finally, the bank adds the total interest earned to your account balance. This increases your account balance and becomes part of the calculation for the next interest-earning period.

Savings account interest calculation also depends on how frequently your bank calculates interest. Interest can be calculated daily, monthly or quarterly.

The more frequently the calculation is made, the more often you will be paid interest payments. With Seacoast's Sail Into Savings account, you will receive automatic interest payments directly into your checking account.


What Type of Account is Best for My Financial Goals?

When comparing savings options, keep in mind that your best option will depend on your needs. If you're saving for short-term needs, consider a high-yield savings account or a money market account. For longer-term goals like buying a home or retirement, consider options like a certificate of deposit (CD) or an IRA for retirement.
