In general, future cash flows get discounted to the present day using this formula: C/(1+r)^n. The “C” is the future cash flow, either positive (a benefit) or negative (a cost). The “r” is the discount rate per period (usually a year). The “n” is the number of periods between now and the time the cash flow occurs.

## How are benefits cost calculated?

The benefit-cost ratio formula is the discounted value of the project’s benefits divided by the discounted value of the project’s costs: BCR = Discounted value of benefits/ discounted value of costs.

## What is the formula for benefit?

The formula for benefit-cost ratio is: Benefit-Cost Ratio = ∑ Present Value of Future Benefits / ∑ Present Value of Future Costs.

## How do you calculate discount rate for NPV?

Formula for the Discount Factor

NPV = F / [ (1 + r)^n ] where, PV = Present Value, F = Future payment (cash flow), r = Discount rate, n = the number of periods in the future).

SDR = WAM = (a)SOC + (1-a)SRTP; where; a = proportion of government project cost funded from current private investment and 1-a = proportion of project cost funded from current consumption. If a > 0, WAM will lie between SOC and SRTP [ SOC > WAM > SRTP].

## How do you calculate net benefit?

Net Benefit is determined by summing all benefits and subtracting the sum of all costs of a project. This output provides an absolute measure of benefits (total dollars), rather than the relative measures provided by B/C ratio.

## How do I calculate benefit cost in Excel?

Benefit-Cost Ratio = PV of Expected Benefits / PV of Expected Costs

- Benefit-Cost Ratio = $10,938.34 / $10,000.

## What is the discount rate formula?

How to calculate discount rate. There are two primary discount rate formulas – the weighted average cost of capital (WACC) and adjusted present value (APV). The WACC discount formula is: WACC = E/V x Ce + D/V x Cd x (1-T), and the APV discount formula is: APV = NPV + PV of the impact of financing.

## How do you calculate discount rate for NPV in Excel?

How to Use the NPV Formula in Excel

- =NPV(discount rate, series of cash flow)
- Step 1: Set a discount rate in a cell.
- Step 2: Establish a series of cash flows (must be in consecutive cells).
- Step 3: Type “=NPV(“ and select the discount rate “,” then select the cash flow cells and “)”.
