How to Use the Present Value Formula
The present value formula is a financial tool that can be used to assess the current value of an investment.
This formula takes into account the time value of money, which is the idea that money today is worth more than money in the future.
In other words, the present value formula can be used to determine how much an investment today is worth given a certain interest rate and time period.
Present Value Formula
The present value formula is relatively simple and is as follows:
PV = FV / (1 + r)^t
Where PV is the present value, FV is the future value, r is the interest rate, and t is the number of periods until the future value is reached.
For example, let’s say you have $100 that you want to invest for 5 years at a 10% annual interest rate.
Using the present value formula, we can calculate that the current value of your investment is $62.50.
Future Value Formula
Now let’s say you want to know how much your investment will be worth in 5 years. We can use the same formula to calculate this, but we would simply rearrange it to solve for FV:
FV = PV * (1 + r)^t
Plugging in our values from before, we would get that the future value of your investment will be $161.
Present Value and Discounted Cash Flow (DCF) Analysis
Discounted cash flow (DCF) analysis is a method of valuing a project, company, or asset using the concepts of the time value of money.
All future cash flows are estimated and discounted back to the present value (PV), using a discount rate that reflects the riskiness of those future cash flows.
A DCF valuation can be done on an individual project or asset level, or it can be done on an entire company.
The two most common methods of discounting cash flows are the net present value (NPV) method and the internal rate of return (IRR) method.
Both methods use the present value formula to discount future cash flows back to the present.
The NPV method discounts cash flows at the weighted average cost of capital (WACC), while the IRR method discounts cash flows at a rate that makes the NPV equal to zero.
The main difference between the two methods is that the IRR method takes into account the reinvestment of cash flows at the IRR, while the NPV method assumes reinvestment at the cost of capital.
The main advantage of DCF analysis is that it explicitly takes into account the time value of money. All future cash flows are discounted back to the present, using a discount rate that reflects the riskiness of those future cash flows.
This makes DCF analysis a good tool for valuing projects, companies, and assets. However, there are also some disadvantages to using this method.
DCF disadvantages
One disadvantage is that DCF analysis requires meticulous forecasting of future cash flows, which can be difficult to do accurately.
Another disadvantage is that the discount rate used in DCF analysis is subjective and can be open to interpretation.
Despite these disadvantages, DCF analysis is still a widely used method of valuation and is an important tool for financial professionals to use as part of their arsenal.
Time Value of Money – Present Value vs Future Value
What Is the Discount Rate for Finding Present Value?
A discount rate for finding the present value is a desired rate of return.
For example, if you were given the financial information about a business – e.g., its revenue, expenses, assets, liabilities, growth rate – and were asked to find out how much you’d be willing to pay for the business, that would depend on your expected rate of return going forward.
If you need only a 5% CAGR going forward, your discount rate would be lower and, accordingly, the price you’d be willing to pay is higher.
If you need 10%, you’d have a higher discount rate and a lower valuation.
Present Value Formula and IRR
The present value formula can also be used to calculate the internal rate of return (IRR) of an investment.
The IRR is the discount rate that makes the present value of an investment equal to its initial cost. In other words, it’s the annualized return you would earn if you held the investment until it reached its maturity date.
To calculate the IRR using the present value formula, we simply set PV = 0 and solve for r.
This gives us the following equation:
r = (FV / PV)^(1/t) – 1
For example, let’s say you want to know the IRR of an investment that will have a future value of $1,000 in 5 years if you invest $621 today.
Plugging our values into the equation above, we would get that the IRR of this investment is 10%. This means that if you held the investment for 5 years, your annualized return would be 10%.

Real or Nominal?
Present value is often calculated using nominal returns and not real returns.
This is an important distinction because if you plug in nominal variables in one part of your model and have real variables in others parts, the results will be thrown off.
So, if you’re looking at revenue growth in nominal terms in your model, you should also use nominal variables in other parts of your model (e.g., nominal risk-free rate, nominal expected rate of return, etc.)
Real or nominal when inflation is higher
Real or nominal is also an important distinction when inflation rates are running high, such that real and nominal diverge from each other.
For example, if inflation is at 10% and nominal interest rates are also at 10%, then real interest rates are actually 0%.
This is an important distinction to make in your models because real and nominal variables often have different implications.
For example, nominal GDP growth might be 5%, but real GDP growth might only be 1%. This could have completely different implications for your business or investment.
Nominal returns are just the dollar value. They don’t convey what was actually bought or the buying power of the dollar amount.
Real returns are what you get. For example, it conveys what you actually got for your spending or how much buying power you’re getting on your investment.
The amount of wealth is not the same as the amount of money you have. It’s about the buying power of the money.
So even though nominal returns are what are most commonly used or referenced in the real world, they are not what’s most important.
Most people pay a lot of attention to what their stocks and other assets are doing in nominal terms, but don’t pay a lot of attention to what the buying power of those numbers mean.
For example, homeowners may spend a lot of time looking at the nominal value of the price of their home, but they don’t pay much attention to what that number means after taking into account inflation and factoring in the overall net economic costs of ownership.
Future Value vs. Present Value
The future value (FV) of an investment is the amount that the investment will be worth at a future date.
The present value (PV) of an investment is the current value of the investment.
Both future value and present value are important concepts in finance because they can be used to assess the current worth of an investment.
Future value is important because it can be used to assess how much an investment will be worth in the future. Present value is important because it can be used to assess how much an investment is worth today.
The time value of money is the idea that money today is worth more than money in the future. This is because money today can be invested and earn interest, while money in the future cannot.
The time value of money is the reason why future value is greater than present value.
The future value formula is: FV = PV (1+r)^n
where:
- FV = future value
- PV = present value
- r = interest rate
- n = number of periods
The present value formula is: PV = FV / (1+r)^n
where:
- PV = present value
- FV = future value
- r = interest rate
- n = number of periods
Criticism of Present Value
The present value approach has been criticized by some because it relies on a number of assumptions that may not be realistic.
For example, the present value approach assumes that the interest rate is known and remains constant over time. This may not be realistic in the real world, where interest rates can fluctuate.
The present value approach also assumes that cash flows are reinvested at the same interest rate. This may not be realistic if the investment is made in different assets with different interest rates.
Finally, the present value approach may give too much weight to short-term cash flows and not enough weight to long-term cash flows.
This is because future cash flows are discounted at a higher rate, which makes them worth less than current cash flows.
This may not be realistic if the investment is expected to generate long-term benefits that are not captured by the present value approach.
In the end, present value calculations are based on projections, which may not be accurate.
Despite these criticisms, the present value approach is still widely used because it is a simple and effective way to assess the current worth of an investment.
The bottom line is that you should be aware of the limitations of the present value approach and use it in conjunction with other valuation methods to get a complete picture of an investment.

Conclusion – Present Value Formula
The present value formula is a simple yet powerful tool that can be used to assess investment values. This formula takes into account the time value of money, which states that money today is worth more than money in the future.
The present value formula can be used to determine how much an investment today is worth given a certain interest rate and time period. Financial professionals can use this formula to make sound investment decisions.
Both formulas are used to assess the current worth of an investment. The future value formula is used to assess the future worth of an investment, while the present value formula is used to assess the current worth of an investment.
The time value of money is the reason why future value is greater than present value. This is because money today can be invested and earn interest.
The time value of money is an important concept in finance because it affects the decisions that people and businesses make about investments.
People and businesses are more likely to invest money if they believe that the investment will be worth more in the future.
In other words, present value takes into account the opportunity cost of investing money today.
The opportunity cost is the potential return that is given up by not investing money today.
For example, if someone has $100 and can either invest it or spend it, the opportunity cost of investing the money is the potential return that could be earned on the investment.
The bottom line is that the time value of money is an important concept in finance because it affects investment decisions. The present value formula takes into account the time value of money and can be used to assess the current worth of an investment.
Financial professionals should be aware of the limitations of this formula and use it in conjunction with other methods to get a complete picture of an investment.
