How to Use the Future Value Calculator
Knowledge of compound growth of money is one of the most valuable concepts in personal finance and investments. The Future Value Calculator is a tool that assists a person in finding out how much their money could be worth in the future if it is allowed to compound on a regular basis. This calculator is made to be clear, realistic, and versatile. Whether the intention is to save money in order to retire, to create an emergency stash of money, to plan long-term investments, or to compare strategies of saving money, the calculator gives an honest presentation of the role of interest in the process of saving. While a basic calculator will display a single answer after calculation, this calculator breaks down the growth over each period in a manner that shows you how different components work together. The calculator is equally useful for simulating a single initial investment as it is for simulating periodic investments, and you have the flexibility of choosing whether you make your investments at the end of the period or the beginning. The projections of growth made visible in charts and a busy schedule help bring intangible concepts of finances to life.
How to Use
1. Enter the Number of Periods
First, you need to enter the total number of periods for which your money will grow. The time period generally stands for one year, though it can also state months or any specific interval of time depending upon your interpretation of your inputs. This is the value that determines the time period of your investment. The longer the time period, the more significant the effect of compounding. A smaller interest rate may lead to a substantial amount if it is applied for a longer number of periods.
2. Enter the Starting Amount (Present Value)
The initial amount is the money you are currently invested. This is represented by any savings you have in a bank account or an initial investment in any fund you are starting with. This value grows with the power of compounding over the entire period. This makes it one of the most influential inputs in the calculator. It is generally a good idea to invest earlier with a lower value.
3. Set the Interest Rate
Enter the expected interest rate or rate of return per period. This rate is the measure of how fast your money is expected to grow. The assumptions that the calculator makes, specifically regarding the rate that's assumed to be constant, work well for long-term projections. Although in real life, there will be variations in investment return, average return assumptions will serve as good yardsticks.
4. Add Periodic Deposits (Optional)
If you anticipate making contributions to your policy by putting money in it periodically, then you can specify how much money you contribute at a desired periodic interval in the table by filling in column C as "5000/period". The table calculates all values for column C as per Periodic payments may have more effect on the final outcome than the initial principal amount. Encouraged saving habits and fast growth are achieved through periodic payments.
5. Choose Deposit Timing (Beginning or End)
Set whether your deposits are made as of the beginning or the end of the periods. This influences the number of periods the money in the starting balance earns interest as it contributes to the balance in the succeeding periods. Such considerations are very important for retirement planning calculations and systematic investments. The calculator makes it clear that timing makes all the difference in results.
6. Calculate and Review Results
After all the variables have been entered, execute the calculation and watch the results appear. Your calculator will show the final value for the future, as well as graphs and an exhaustive growth table. These outputs allow you to determine not only where you finish, but how you get there, period by period.
Key Formulas Used
Where: PV = starting amount r = interest rate per period n = number of periods This formula calculates how a single amount grows when interest is compounded over time.
This formula adds the effect of regular deposits made at the end of each period, showing how systematic investing accelerates growth.
When deposits are made at the beginning of each period, they earn interest for an additional cycle, increasing the final value.

Related Calculators
What is this?
Future Value (FV) shows what your starting amount and regular deposits grow to with compounding. Includes deposit timing (beginning/end) and a full schedule.
How it works
FV = PV × (1 + r)^N + PMT × ((1 + r)^N − 1)/r × [1 + r if deposits at beginning]. The schedule shows Start balance, Deposit, Interest, End balance each period.
Pro Tips
- Choosing 'beginning' compounds deposits sooner and increases growth.
- Even small increases in rate or deposits compound significantly over time.
- Use the schedule to audit calculations period-by-period.
Frequently Asked Questions
What is future value?
Future value (FV) represents how much a starting amount of money will grow over time when interest is compounded and deposits are added periodically.
What is the difference between present value and future value?
Present value calculates what future money is worth today, while future value calculates how today’s money grows into the future.
What does PMT mean in this calculator?
PMT refers to the periodic deposit amount added each period, such as a monthly or yearly contribution.
What is the difference between deposits at the beginning vs end?
Deposits made at the beginning of a period earn interest for the entire period, resulting in higher future value compared to deposits made at the end.
How does compound interest affect future value?
Compound interest allows interest to earn interest over time, significantly increasing growth compared to simple interest.
Why does increasing the rate or periods increase FV so much?
Compounding accelerates growth over longer time horizons, so even small increases in rate or duration can produce large differences.
When should I use a future value calculator?
Use it to plan investments, savings goals, retirement contributions, or any scenario involving growth over time.
