The quoted market rate for traded instruments quoted at a discount.  


The number less than one which we multiply a single future cash flow by, to work out its present value as:
The market discount rate is quoted based on a percentage of the ''maturity amount''.


PV = DF x future cashflow.

The periodic discount factor is calculated from the periodic [[yield]] as:
The maturity amount for an investment is £10m.


DF = (1 + periodic yield)<SUP>-n</SUP>
The gain for the single period from the start to the final maturity is £2m.


The periodic discount rate (d) is:


Commonly abbreviated as DF(n,r) ''or'' DF<SUB>n,r</SUB>
(d) = Gain / End amount


Where:
= 2 / 10


n = number of periods.

r = periodic yield (or periodic cost of capital).


In the US the market discount rate is sometimes known as the ''discount yield''.


This is different from a [[yield]] or interest rate, which is conventionally quoted based on a percentage of the ''starting amount''.

Number of periods in the total time under review (n) = 1.  
The starting amount for an investment is £8m.


The gain for the single period from the start to the final maturity is £2m.


Discount factor = (1 + r)<sup>-n</sup>
The periodic yield (r) is:

(r) = Gain / Start amount

The greater the time delay, the smaller the Discount Factor.


Notice that the discount rate and the yield calculated above both relate to exactly the same deal.

£8m is invested now, and £10m is repaid at the end of one period.


Periodic yield or cost of capital = 6%.  
The discount rate of 20% and the yield of 25% both summarise the same deal, using different conventional bases.

The rate used to discount future liabilities of a Defined benefit pension scheme in order to calculate the present value of the liabilities, often for the purpose of comparing them with the market value of the scheme’s assets.


The yield or cost of capital used for the purpose of calculating Discount Factors, as defined above.
Historically it was common to use the blended rate of investment return expected on the actual assets in the scheme, but typically now a market rate is used, such as the government bond or AA corporate bond yield for a fixed income security with a similar duration to that of the underlying liabilities.


For example the 6% rate applied in definition 1. above.

In the US, the interest rate that member banks pay the Federal Reserve when the banks use securities as collateral.  The discount rate acts as a benchmark for interest rates issued.
 
Other central banks also have similar discount rates.

1.

The quoted market rate for traded instruments quoted at a discount.

The market discount rate is quoted based on a percentage of the maturity amount.


Example 1: Discount rate calculation

The maturity amount for an investment is £10m.

The gain for the single period from the start to the final maturity is £2m.

The periodic discount rate (d) is:

(d) = Gain / End amount

= 2 / 10

= 20%


In the US the market discount rate is sometimes known as the discount yield.

This is different from a yield or interest rate, which is conventionally quoted based on a percentage of the starting amount.


Example 2: Yield calculation

The starting amount for an investment is £8m.

The gain for the single period from the start to the final maturity is £2m.

The periodic yield (r) is:

(r) = Gain / Start amount

= 2 / 8

= 25%


Notice that the discount rate and the yield calculated above both relate to exactly the same deal.

£8m is invested now, and £10m is repaid at the end of one period.

The discount rate of 20% and the yield of 25% both summarise the same deal, using different conventional bases.


2.

Cost of capital.

The yield used to calculate discount factors and present values.


3.

The rate used to discount future liabilities of a Defined benefit pension scheme in order to calculate the present value of the liabilities, often for the purpose of comparing them with the market value of the scheme’s assets.

Historically it was common to use the blended rate of investment return expected on the actual assets in the scheme, but typically now a market rate is used, such as the government bond or AA corporate bond yield for a fixed income security with a similar duration to that of the underlying liabilities.


4.

In the US, the interest rate that member banks pay the Federal Reserve when the banks use securities as collateral. The discount rate acts as a benchmark for interest rates issued.

Other central banks also have similar discount rates.
