We believe everyone should be able to make financial decisions with confidence. Note that if you wish to calculate future projections without compound interest, we have acalculator for simple interest without compounding. Peter Carleton is a writer that covers banking and investing, breaking down what you need to know about where you put your money.
Start by entering your initial deposit or investment, or your current balance if you already have a deposit. Then enter how long you want to keep the deposit or investment, usually in years, but we also support other time periods. This variation of the formula works for calculating time (t), by using natural logarithms. You can use it to calculatehow long it might take you to reach your savings target, based upon an initial balance and interest rate. Youcan see how this formula was worked out by reading this explanation on algebra.com.
The more times the interest is compounded within the year, the higher the effective annual rate will be. The following chart demonstrates the difference that the number of compounding periods can make for a $10,000 investment with an annual 7% interest rate over a 10-year period. Note, that if you leave the initial and final balances unchanged, a higher the compounding frequency will require a lower interest rate.

Compound interest takes into account both interest on the principal balance and interest on previously-earned interest. Simple interest refers only to interest earned on the principal balance; interest earned on interest is not taken into account. To see how compound interest differs from simple interest, use our simple lease accounting for escalating rent payments or rent holidays interest vs compound interest calculator. Just enter your beginning balance, the regular deposit amount at any specified interval, the interest rate, compounding interval, and the number of years you expect to allow your investment to grow. Where I is the effective interest rate and the rest of the notation is as above.

Assuming that the interest rate is equal to 4% and it is compounded yearly. Find the number of years after which the initial balance will double. Generally, compound interest is defined as interest that is earned not solely on the initial amount invested but also on any further interest. In other words, compound interest is the interest on both the initial principal and the interest which has been accumulated on this principle so far. Therefore, the fundamental characteristic of compound interest is that interest itself earns interest. This concept of adding a carrying charge makes a deposit or loan grow at a faster rate.

- We’ll say you have $10,000 in a savings account earning5% interest per year, with annual compounding.
As you can see this time, the formula is not very simple and requires a lot of calculations. That’s why it’s worth testing our compound interest calculator, which solves the same equations in an instant, saving you time and effort. In this example you earned $1,000 out of the initial investment of $2,000 within the six years, meaning that your annual rate was equal to 6.9913%.
Then, raise that figure to the power of the number of days you want to compound for. Subtract the starting balance from your total if you want just the interest figure. If you want to roughly calculate compound interest on a savings figure, without using a calculator, you can use a formula calledthe rule of 72.
It also allows you to answer some other questions, such as how long it will take to double your investment. If your initial investment is $5,000 with a 0.5% daily interest rate, your interest after the first day will be $25. If you choose an 80% daily reinvestment rate, $20 will be added to your investment balance,giving you a total of $5020 at the end of day one. The compound interest calculator is designed to discover the potential growth of your savings or investments over time. Compound interest occurs when interest is added to the original deposit – or principal – which results in interest earning interest. Financial institutions often offer compound interest on deposits, compounding on a regular basis – usually monthly or annually.
By using the Compound Interest Calculator, you can compare two completely different investments. However, it is important to understand the effects of changing just one variable.

When it comes to retirement planning, there are only 4 paths you can choose.
Compound Interest Formula (with regular deposits)
Let’s go back to the savings account example above and use the daily compound interest calculator to see the impact of regular contributions. We started with $10,000 and ended up with $4,918 in interest after 10 years in an account with a 4% annual yield. But by depositing an additional $100 each month into your savings account, you’d end up with $29,648 after 10 years, when compounded daily. In general, for savings accounts, interest can be compounded at either the start or the end of the compounding period (this is usually every month or every year). If additional contributions are included in your calculation, the compound interest calculator will assume that these contributions are made at the start of each period.
Note that in the case where you make a deposit into a bank (e.g., put money in your savings account), you have, from a financial perspective, lent money to the bank. For example, $100 with a fixed rate of return of 8% will take approximately nine (72 / 8) years to grow to $200. Bear in mind that “8” denotes 8%, and users should avoid converting it to decimal form. The Compound Interest Calculator below can be used to compare or convert the interest rates of different compounding periods. Please use our Interest Calculator to do actual calculations on compound interest.
The amount you invest in a savings account earns interest, which is rolled into the total investment. The total investment continues earning interest – only this time, on a bigger balance than before. Here’s how different compounding period intervals are affecting the total amount generated and interest earned.
Using the compound interest calculator
Or,you may be considering retirement and wondering how long your money might last with regular withdrawals. You can include regular withdrawals within your compound interest calculation as either a monetary withdrawal or as a percentage of interest/earnings. We’ll use a longer investment compounding period (20 years) at 10% per year, to keep the sumsimple. FV – The FV function calculates the future value of an annuity investment based on constant-amount periodic payments and a constant interest rate. If you invested $10,000 which compounded annually at 7%, it would be worth over $76,122.55 after 30 years, accruing over $66,122.55 in compounded interest. More so if you look at the graph below, the benefits of compound interest outweigh standard interest by $45,122.55.
When Peter’s not thinking about cutting-edge banking apps and robo-advisors, he runs a creative agency and spends his spare time cooking or reading. That amount will then grow by 10% the following year, bringing your balance to $1,210. After 5 years, your original balance would have grown to $1,610 due simply to compounding interest. The results of this calculator are shown in future value of the money. If you turn on the “Inflation (%)” option, then you can also see the adjusted for inflation value as well. You can how over the chart bars to see individual metrics for any of the calculated yearly time series.

Note that the values from the column Present worth factor are used to compute the present value of the investment when you know its future value. Have you ever wondered how many years it will take for your investment to double its value? Besides its other capabilities, our calculator can help you to answer this question. To understand how it does it, let’s take a look at the following example.
