What is a savings calculator?
A Savings Calculator helps you plan toward a savings goal, such as an emergency fund, a down payment, a car or a wedding. Enter what you have now, what you can add each month or year and the rate your account pays, and it shows your balance at the end, how much of it is interest and a year-by-year schedule. Try different monthly amounts to find the one that reaches your goal in time.
How to use it
- Enter your initial deposit.
- Enter any annual and monthly contribution, with an optional yearly increase.
- Enter the account’s interest rate and compounding frequency.
- Enter the years to save and, if interest is taxable, your tax rate.
- Click Calculate.
How Savings Accounts Work
A savings account is a deposit account offered by banks, credit unions, and other financial institutions that allows people to store money while earning interest. Savings accounts are generally designed for money that is not needed for immediate everyday spending. They typically provide easier access to funds than long-term investments, although some accounts may have withdrawal restrictions, minimum balance requirements, or monthly fees.
Savings accounts can differ significantly in their interest rates, fees, minimum balance requirements, and other conditions. The annual percentage yield (APY) is particularly useful when comparing accounts because it reflects the effect of compounding. A higher APY can help savings grow faster when money remains deposited for a longer period.
Savings formulas
Balance with deposits: FV = P(1 + r/n)^(nt) + PMT × [((1 + r/n)^(nt) − 1) ÷ (r/n)]
Monthly saving needed for a goal: PMT = (Goal − P(1 + i)^N) × i ÷ ((1 + i)^N − 1)
Here P is your starting balance, PMT is the regular deposit, r is the annual rate, n is the number of deposits and compounding periods per year, t is the number of years, i = r ÷ 12 and N is the number of months.
Example 1: how much will I have?
Start with $5,000, add $200 a month and earn 4% compounded monthly for 10 years. The balance grows to about $36,904; you deposited $29,000, so about $7,904 is interest.
Example 2: how much do I need to save?
You want $20,000 in 5 years, already have $5,000 and earn 4%. The $5,000 grows to about $6,105, so you need to save about $209.58 a month to cover the rest.
How Much Should You Save?
There is no single savings amount that works for everyone because financial goals, income, expenses, debt, and existing savings differ from person to person. Some people may focus first on building an emergency fund, while others may prioritize a home purchase, education, retirement, or another long-term objective. A common approach is to maintain enough accessible savings to cover several months of essential expenses.
Regular contributions can make saving easier because smaller amounts accumulated consistently may grow significantly over longer periods. The important factors are the amount saved, how frequently contributions are made, the rate earned, and how long the money remains invested. Using a Savings Calculator can help you test different contribution amounts and time periods before choosing a savings target.
Tips
- Automate a transfer on payday so saving happens first.
- Keep your emergency fund in an insured savings account you can reach quickly.
- Compare accounts by APY and check for monthly fees.
- Raise your monthly amount when your income goes up; the increase field shows the effect.
Frequently Asked Questions
Use PMT = (Goal − P(1 + i)^N) × i ÷ ((1 + i)^N − 1), or try amounts in the calculator until the end balance matches your goal. For example, to reach $20,000 in 5 years from $5,000 at 4%, you need to save about $209.58 a month.
Compound interest allows previously earned interest to become part of the balance used to calculate future interest. Over longer periods, this can significantly increase the growth of savings.
A common rule of thumb is to save at least 10% to 20% of take-home pay and to build an emergency fund of three to six months of essential expenses first. The right amount depends on your goals and timeline.
APY stands for Annual Percentage Yield. It reflects the annual return on a savings account while taking the effect of compounding into consideration, making it useful for comparing savings accounts.
Yes. Regular contributions can increase the final balance because each deposit adds to the amount being saved and may also have time to earn interest.
