Savings Calculator
This savings calculator, also known as a savings account calculator, is a multifunctional tool that helps you to create a precise savings plan so that you can save up enough money to buy your dream car or holiday. It works in various ways: you can either find out how much you'll save, how much your initial saving should be, or how much you need to deposit over a chosen period if you want to reach your saving goal. You can also estimate how much time it takes to save a desired amount and what interest rate you need to arrive at a given balance.
The real strength of this tool is that you can accurately model any situation. For example, in the advanced mode you can add the average inflation rate, which allows you to learn the purchasing power of your savings. There is also a dynamic graph where you can study your results visually. The Final Balance Breakdown and the chart of your Annual Balances provide you with detailed balances, allowing you to follow the progress of your savings account easily over time.

Some practical notes on savings
As you probably already know, it is generally not a good idea to save money by putting it all under your mattress. Even if you want to put cash aside, there are multiple reasons to instead deposit it in a bank or other financial institution in the form of a bank account. A prominent reason for relying on such financial transactions is the fact that an interest rate is applied to your balance, which is usually higher than the inflation rate. In this way, your money is not only secured against possible thievery (and mice) but also protected against inflation. One of the drawbacks, however, is how accessible specific bank accounts make your money. To understand this, let's go through the most common types of bank accounts, which are the following:
 Current account or checking account
This type of account is the most liquid one, as you can access your money at any time through multiple channels (i.e., debit card, withdrawal, writing a cheque). Usually, there is no or minimal interest paid on this kind of account.
 Savings account
You receive interest, but the bank limits the usage of the funds to ATM withdrawals only.
 Time deposit or certificate of deposit (CD)
The deposited money is fixed in the account for a specific time, and the bank imposes a penalty for premature withdrawals. The longer the deposit period, typically, the higher the interest rate banks offer. However, this can vary based on specific offers and policies of different financial institutions.
 Call deposit
A deposit account that allows for the withdrawal of funds without penalty but requires a higher minimum balance to earn interest.
As you probably noticed, the degree of accessibility of your money and the interest rate offered are linked in the opposite manner (inversely proportional). In other words, the more you restrict your ability to use your money, the more interest you accumulate on your account.
The other benefit of keeping your money in a bank account is safety: your money is less exposed to market fluctuations than other investments and is also secured by regulations. For example, many countries, including the U.S.A., implemented deposit insurance to protect bank depositors, in full or in part, from losses caused by the bank's failure to pay its debts when due. Of course, if you feel more confident and fancy highrisk, highreward scenarios, you may instead choose to invest your money in a stock or bond market.
Savings calculator's specifications
Before you decide to open a savings account, you need to know how different factors affect your balance. Besides, to be able to apply this calculator properly and to understand the equations that govern it, it is essential to get familiar with these specifications:
 Initial deposit and desired savings
The opening balance is the amount that you have when you open your account, and the final balance is the amount that you would like to reach. In financial terms, they are the present value and the future value, which are linked together by the time value of money, which is one of the most fundamental concepts in finance. To learn more about how the present and future values are related in an investment, you may like to check out the IRR calculator or the time value of money calculator.
 Interest rate and APY
Interest rate is one of the most important factors when you are about to choose a savings account. It refers to the nominal interest rate, also known as simple interest (or the headline or quoted interest rate). When you look around different offers, however, you most probably see APY (Annual Percentage Yield), which is another type of rate often quoted for savings accounts. The power of APY is the fact that it incorporates the effect of compounding. Therefore, it removes one of the main drawbacks of the nominal interest rate. For your convenience, this calculator lets you choose which rate you would like to use.
 Time length
It is the time frame that you decide to give up the use of your savings and put aside some money.
 Compound frequency
Compound interest is one of the most powerful concepts in finance and is present in most financial/investment products. In this context, compound interest might be defined as a gain that is earned not merely on the annual opening balance but also on the previously earned interest. If interest is calculated on any prior interest, the more often interest calculations (compounding) occur, the more money you will earn. Eventually, this can have a significant effect on the final balance, especially in the long term. The most simple compounding frequency is yearly, which means that interest is calculated on your balance annually. In this case, the nominal interest rate is equal to the APY. In practice, however, compounding occurs more often, for example, semiannually or monthly, depending on the type of financial instrument and practice. Compounding may be applied even more frequently. Theoretically, it can reach its highest frequency, called continuous compounding, which is the mathematical limit of the procedure. For more insight into the background behind this, you can learn some interesting details in the Natural logarithm section of the log calculator.
 Annual inflation rate
Since inflation can substantially change the buying power of an amount of money, it is essential to consider its effects. When the inflation rate is high, the real inflationadjusted interest rate, or the real interest rate, on your balance is lower**. In such a case, the nominal interest rate** may not even compensate for the purchasing power loss caused by hikes in the general price level. Although you have a gain in nominal terms, in real terms, you lost on the transaction. You can include the inflation rate in the advanced mode of this savings calculator.
 Additional deposit
In this section, you may set a specific amount that you intend to add to your savings account during its term. Besides its amount (How much?), you can specify its regularity (How often?) and its timing (When?), which can be the beginning of or the end of the period. Also, you can set an annual growth rate or periodic growth rate if you expect to put aside more money each year. The option to set a growth rate for the additional deposit allows you to model an anticipated increase in the money devoted to your savings or to compensate for the purchasing power loss resulting from inflation.
How savings account calculator works
Our savings calculator has five distinct ways in which it can be used. This is done by setting the subject of your interest at the top of the tool in the field titled "I would like to know..". These functions allow you to analyze your savings plan in multiple aspects, which are the following:

What will be the final balance? — Savings balance

What should the starting amount be to reach your savings target? — Initial deposit

How much money should I put aside? — Additional deposit

How long will it take to realize my desired savings? — Time length

What should the interest rate on your savings account be to obtain a sufficient amount of money? — Interest rate
Below, we have set out two basic examples to represent the problems you may face when making a savings plan.
Firstly, let's say you are saving for your dream bike, and you would like to know how much money you need to put aside (additional deposit) to realize your dream:

Find out the price of the bike. Let's say it is
$2000
— and this is our desired savings that we want to achieve. 
Determine your initial deposit. Let's make it
$1200
. 
Find out the interest rate. We've found a savings account with a
1.93%
interest rate. 
Last but not least, decide about the time length you want to save for. Let's say we are not in a hurry and can save over
2 years
. 
Regarding the compounding frequency, you learn that the savings account you would choose is compounding
monthly
. 
Also, you set the frequency of your additional deposit to
monthly
, which occurs at theend of the period
. 
For simplicity, you don't count on inflation as you hope that the price of the bike will not change in such a short interval. You also do not choose to set an annual growth or periodic growth rate in the advanced mode for your additional deposits.

By entering this data in our calculator, you will calculate that you only have to deposit
$30.79
monthly to buy that bike in 2 years. Congratulations!
The other way to use the savings account calculator is to find out the initial deposit you need to put down (initial deposit) if you know how much we can deposit monthly:

Determine the final savings balance. Let's make it
$3000
. 
Find out monthly additional deposit. Let's say we can deposit
$120
monthly. 
Set the time length. Let's say
9 months
is the deadline. 
Finally, enter the APY. Let's use
1.95%
with amonthly
compounding frequency. 
For simplicity, we will skip the setup for the inflation rate, annual growth and periodic growth rate again.

By entering this data, you will find out that you will need to put down an initial deposit of
$1883.78
.
To see how your money will grow, you can study the monthly and yearly balances in a table at the bottom of the calculator to check what makes up your final balance. We also created a bar chart, where you can visually follow the progression of your balances.
Note that the parameters of annual inflation rate and periodic/yearly growth rate of deposit can be found in the advanced mode.
FAQ
How much money do I need to deposit to accumulate 5000 in 7 years?
Assuming that your bank pays an interest rate of 5%
per annum, you would need to deposit $3553.41 to accumulate $5000 in a 7year period. We calculate this by using the compound interest formula:
Amount = P (1 + ^{r}/_{n})^{nt}
Substitute the values:
5000 = P(1 + ^{0.05}/_{1})^{1 × 7}
Make P the subject of the formula and calculate:
P = 5000/(1 + 0.05)^{7}
P = 3553.41
How is savings account interest calculated?
The interest on savings accounts is calculated using compound interest. To calculate the interest gained on your account, follow these steps:

Get the original amount saved (P).

Get the saving period in years (t).

Get the interest rate (r).

Get the frequency with which interest is calculated in a year (n).

Apply the compound interest formula below to find the total amount of money that will be in your account at the end of the period:
Amount = P (1 + ^{r}/_{n})^{nt}

Calculate the interest earned using the following formula:
Total interest = Amount − P
What is a high yield savings account?
A highyield savings account has an interest rate of approximately 10 to 12 times higher than a traditional one. This means that the money in your account can grow significantly faster than in a conventional one.
Unlike traditional savings accounts, highyield ones may have more stringent withdrawal limits. Additionally, they may have stricter qualifying requirements.
What is my interest rate if I accumulated $7563 after 12 years?
Assuming that the amount in your account at the beginning of the period was $4500 and you made no deposits or withdrawals, the interest rate is 4.42%.
To find this answer, we used the compound interest formula:
Amount = P (1 + ^{r}/_{n})^{nt}
where:
 P — Amount of money you started with;
 n — Number of times interest is paid in a year;
 t — Number of years; and
 r — Annual interest rate.
