Net Present Value
Calculating NPV helps determine the value of all future cash flows for the life of an investment discounted to the present day.
Net present value, or NPV, represents the value of all future positive and negative cash flows over the lifespan of an investment.
Net present value calculations are comprehensive. They account for virtually all revenues, expenses, and capital costs. The metric takes the time value of each cash flow into account as well, discounting to the present time. This can significantly impact the present value of an investment.
An NPV calculations is very important because it plays a large role in comprehensively assessing the value of an investment — or any series of cash flows.
How to Calculate Net Present Value
To find the net present value of an investment, use the formulas below. Note that the complexity of the calculation will grow if your asset has more than one cash flow.
Your first step is to calculate the negative and positive cash flows — costs and income — for each period of an investment's lifespan. Once you have your cash flow for each period, discount its future value using a periodic rate of return to find your present value, or PV.
The rate of return used in the calculation is dictated by the market. The sum of all of the discounted future cash flows is the net present value of an investment.
The Net Present Value Formula
In simplest terms, the formula for NPV can be described as the current value of expected cash flows less the current value of the cash invested, or:
Net Present Value = Current Value of Expected Cash Flows - Current Value of Cash Invested
The actual formulas used to determine net present value are a bit more complex. The core principles remain the same no matter how the formula is presented, though. NPV can be calculated for a single cash flow or for an asset with multiple cash flows using the appropriate formula below.
To calculate the net present value of an asset with a single cash flow, the formula is as follows:

Where:
“i” represents the discount rate

To calculate the NPV of an asset with multiple cash flows, the formula is:
Where:
“Rt” represents the net cash inflow-outflows during a period of time
“i” represents the discount rate
“t” represents the number of time periods
Negative vs. Positive Net Present Value
In short, a positive net present value is far better than a negative one. A negative NPV does not mean the investment will not turn any profit, though it does indicate a loss in value. A positive NPV is ideal — it shows that earnings will exceed anticipated costs over time.
Net Present Value and Internal Rate of Return
The internal rate of return (IRR) is another common metric used in financial analysis. In its simplest terms, the IRR is the discount rate that would result in an NPV of zero. The IRR represents the compound annual return expected over the life of an investment. In finance, NPV and IRR metrics both factor into any major investment decision.
Related Questions
What is the definition of net present value?
Net Present Value, often shortened to NPV, is a metric that represents the value of all future cash flows (both positive and negative) over the entire lifespan of an investment, discounted to the present time. The determination of the NPV metric is used extensively across finance and accounting as a form of intrinsic valuation for determining the value of an investment, capital project, business, cost reduction program, and other entities and practices that involve cash flow.
Net present value analysis is used in the determination of how much an investment, project, or really any series of cash flows is worth. NPV as a metric is all-encompassing, since its calculation accounts for all revenues, expenses, and capital costs associated with an investment in its Free Cash Flow (FCF). Additionally, the NPV metric also takes into account the time value of each cash flow. Cash flow timing can largely impact the present value of an investment.
How is net present value used in commercial real estate?
Net present value is used in commercial real estate to help investors determine whether they're getting a certain return or 'target yield' given the amount of their initial investment. The NPV equation takes a building's current net cash flows and the investor's required rate of return to determine a building's value to the investor right now. Investors can calculate NPV using the formula NPV = C1/(1+r)^1 + C2/(1+r)^2 + ... + CN/(1+r)^N, where "C" represents the sum of cash flows, "n" represents each period, "N" represents the holding period, and "r" represents the desired target yield, or required rate rate of return.
What are the advantages of using net present value in small business financing?
Net present value (NPV) is a useful tool for small business owners to evaluate the profitability of a potential investment or project. NPV takes into account the time value of money, risk, and other factors to determine the profitability of an investment. The advantages of using NPV in small business financing include:
- NPV takes into account the time value of money, which is important for small business owners to consider when evaluating the profitability of an investment.
- NPV also takes into account the risk associated with an investment, which is important for small business owners to consider when evaluating the profitability of an investment.
- NPV can be used to compare different investment opportunities and determine which one is the most profitable.
- NPV can be used to determine the optimal financing structure for a small business.

What are the disadvantages of using net present value in commercial real estate?
The main disadvantage of using net present value (NPV) in commercial real estate is that it does not compensate for uneven cash flows. For example, if a building generates $0 in years 1-4 and $500,000 in cash in year 5, the NPV for that period would be the same. Additionally, NPV does not compensate for the size of a transaction; the NPV on a $1,000 investment that returned $4,000 would be the same as the NPV for a $10 million investment that returned $30 million. However, most investors would likely be far more interested in the second deal.
How is net present value calculated in small business financing?
Net present value (NPV) is a useful and easy to calculate metric to determine the profitability of a given project or investment. The net present value of an investment is found by calculating the negative cash flows (costs) and positive cash flows (income) for each period during the lifespan of an investment. Once the cashflow for each period is determined, the present value (PV) of each period can be calculated by discounting its future value at a periodic rate of return. The rate of return used in this calculation is dictated by the market. The net present value is the sum of all of the discounted future cash flows.
In small business financing, the net present value is calculated using the formula below. "C" represents the sum of cash flows, "n" represents each period, "N" represents the holding period, and "r" represents the desired target yield, or required rate rate of return.
What are the best practices for using net present value in commercial real estate?
The best practices for using net present value in commercial real estate include:
- Calculating the NPV of a potential investment to determine if it is worth pursuing.
- Comparing the NPV of different investments to determine which one is the most profitable.
- Using the NPV equation to determine the value of a building to an investor.
- Considering the time value of money when calculating the NPV.
