Future Value Calculator

Future Value Calculator: See What Your Money Will Be Worth

This future value calculator will show you how much your money today will grow into by a future date, or it will work backward to tell you what a future sum is worth in today’s dollars. Switch between FV and PV modes, add your amount, rate, time period and optional recurring contribution and get your answer immediately.

Most online future value calculator provide future value and present value in two separate calculators. Indeed, they are the same formula backward; hence, this FV calculator calculates both in one place, with the math fully explained so you can understand exactly how each figure was arrived at.

The Time Value of Money: Why $1,000 Today Beats $1,000 Later

All of the figures on this page are based on the assumption that $1,000 today is worth more than a promise of $1,000 five years from now. Not just because of inflation (though that’s a part of it), but because money today may be invested.

Put your $1,000 to work now with a good rate of return and watch it grow. If you let it sit for five years it could be worth $1,300, or $1,400, or more, depending on the rate. Then when you get the $1,000 you missed all that progress. This is termed finance, the time value of money, and the theory driving every time value of future value calculator whether the inquiry is “What will this be worth later?” or “What is that future amount worth right now?” 

Money has a time dimension, not just a dollar amount, therefore future worth and present value are no longer separate topics. They are the same question in reverse directions.

The Future Value Formula (Single Sum)

A future value calculator is an answer to the question: What will it become at a future date if I make a fixed investment today?

FV = PV × (1 + r)^n

• PPV = present value, the amount you start with 
• r = your interest rate or expected return each period
• n = number of periods (normally years)

Worked Example: You invest $5,000 in an account today at 6% per annum for 10 years.

FV = $5,000 × (1.06)^10 = $5,000 × 1.790847 = $8,954.24

At 6% you will have just under $8,954 in 10 years’ time without putting another dime on top of the $5,000. That’s the power of compounding your earnings earning earnings, year after year.

Future Value With Regular Contributions

Most people don’t just invest a flat sum and then walk away. They keep on adding to it. This is the equation to determine the future value with the help of a future value calculator of money when you are investing on a set schedule:

FV = C × [((1 + r)^n − 1) ÷ r]

• C = periodic contribution (e.g. monthly contribution)

• r = interest rate per period (annual rate / 12 if monthly)

• n = number of periods in total

Worked example: You contribute $200 a month earning a 6% annual return (0.5% a month) for 10 years (120 months).

FV = $200 × (1.005)^120 – 1 ) / 0.005 = $200 × 163.88 = $32,776

If you put in $200 a month for 10 years, you will have around $32,776. That’s a lot more than the $24,000 you contributed ($200 x 120 months). That’s the power of compounding on every dollar you put in over time.

The Present Value Formula (Working Backwards)

Present value turns the question around. If I am guaranteed some amount in the future how much is it worth to me today?

PV = FV ÷ (1 + r)^n

That is the same as the above future value calculation flipped upside down. You are discounting a future sum back to the present. You are not compounding money forward in time.

Worked example: Using the same figures as in the future value calculator example, what is $8,954.24 in 10 years worth today at a 6% rate?

PV = $8,954.24 / (1.06)10 = $8,954.24 / 1.790847 = $5,000.00

This brings us right back to the $5,000 we started with in the future value of money calculator example. This is not a coincidence this is evidence that the future value and the present value are just two ways of looking at the same calculation. If you grow $5,000 forward 10 years you get to $8,954.24. $8,954.24 discounted ten years ago will equal $5,000.

Present Value of Future Payments (Recurring)

Sometimes, however, you’re not looking at a single future lump amount, but a series of future payments, such as a settlement handed out monthly or a pension. So here is the formula for the present value calculator as such:

PV = C × [(1 − (1 + r)^−n) ÷ r]

Worked example: What is a promise of $200 a month for 10 years worth today assuming a 6% annual rate (0.5% monthly)?

PV = $200 * [ (1 – (1.005) ^ -120 ) / 0.005 ] = $200 * 90.07 = $18,015

Thus a commitment to receive $200 a month for the next 10 years is worth about $18,015 in today’s dollars, not the full $24,000 you might get if you tallied up all the payments. That disparity is the time value money calculator of money in action: A payment years down the road is worth less today than a payment coming sooner.

Real-Life Uses: Future Value and Present Value in Action

These formulas show up in everyday decisions more often than people realize:

• • Settlement offer comparison. Say you are offered $50,000 immediately or $60,000 over 5 years. A present value calculation informs you which is actually worth more today , provided you put in a sensible discount rate.
  • Options Lottery or Lump Sum Payment. Often lottery winners are asked to pick between a smaller amount paid now and a greater amount paid over 20 to 30 years. That’s the appropriate way to do the comparison with present-value math.
  • Create a savings goal. Future value calculator math (worked backward) informs you how much to invest today or donate monthly to accomplish that aim. If you desire $50,000 for a down payment in 5 years.
  • Investment assessment – the fundamentals of business. Small business entrepreneurs utilize present value to determine if the future return on an investment is truly worth the initial investment after considering time and an acceptable rate.

Anywhere money moves through time instead of changing hands instantly, this value-of-money calculator logic applies.

What Discount/Interest Rate Should You Use?

The rate you choose changes your answer significantly, so pick it deliberately rather than guessing.

• If you want to be conservative, consider a savings account or bond rate because they are safe and low risk and give you a return.
• Use an expected investment return from your actual portfolio or asset mix for growth projections.
• The higher your estimated rate the less you value money today in the future. The lower your rate the more you value it. If you are considering a settlement offer or payout decision, then a relatively minor change in the rate you assume can tip the decision to the “better” one therefore it’s worth trying a couple of fair rates rather than just one number.

Frequently Asked Questions

Q1. What is the future value formula?

FV = PV × (1 + r)^n, where PV is your starting amount, r is the interest rate each period and n is the number of periods. In our example, $5,000 invested now at 6% for 10 years would grow to $8,954.24.

Q2. What is the present value formula?

PV = FV / (1 + r) ^ n. It’s the exact counterpart of the future value formula, discounting a future sum back to what it’s worth now. Using the same calculations as our FV example, $8,954.24 received in 10 years discounted at 6% is worth exactly $5,000 now.

Q3. Why is money today worth more than the same amount in the future?

Because money now can be invested and increase. A dollar you have now can start earning a return instantly, while a dollar promised later hasn’t had that chance yet. This disparity is called the time value of money, and it’s the explanation behind every future value and present value calculation. 

Q4. How do I calculate future value with monthly contributions?

FV = C x [((1 + r)^n – 1) / r] where C is your contribution each period. In our example, $200/month for 10 years at 6%, compounded annually, will amount to something like $32,776.

Q5. What interest rate should I use in a present value calculation?

Use a bond or savings rate for a conservative forecast or an expected return on investment for a growth-oriented projection. Remember that a higher rate makes future money less valuable today, so the rate you choose may significantly affect your result.

Q6. Is present value the same as future value discounted?

Yes. Present value is just the future value calculator value backward, taking a future quantity and discounting it back to today’s values at the same rate and time period. The two formulas are mirror reflections of each other. This is illustrated in the worked examples above.

Conclusion

Future value calculator and present value are not two different things to learn they are the same time-value-of-money notion seen from opposite directions. Once you understand that generating money ahead and discounting it backward are actually the exact same math, both methods become much easier to believe and use. Use the calculator above to run your own numbers, whether you’re estimating a savings goal, considering a payment offer or just curious what today’s cash will be worth years down the line.

Not financial advice. All formulas and worked examples above are computed independently and verified against the calculator’s own output, with the present value example confirmed to correctly invert the future value example. Last updated: August 2026.
