[2] [6] The "discount rate" is the rate at which the "discount" must grow as the delay in payment is extended. [7] This fact is directly tied into the time value of money and its calculations.

Hyperbolic discounting is mathematically described as = + where g(D) is the discount factor that multiplies the value of the reward, D is the delay in the reward, and k is a parameter governing the degree of discounting (for example, the interest rate).
Discount rates and traditional economic problems both inform and are influenced by each other. For example, the interest rate plays an important role in individual discount rates. If one can accumulate interest at a certain rate, say 5% per year, one should not have a discount rate below this. Say you are offered $100 today or $105 in one year.
In economics, discounted utility is the utility (desirability) of some future event, such as consuming a certain amount of a good, as perceived at the present time as opposed to at the time of its occurrence. [1]
The discount rate is assumed to be constant over the life of an investment; however, discount rates can change over time. For example, discount rates can change as the cost of capital changes. [ 16 ] [ 10 ] There are other drawbacks to the NPV method, such as the fact that it displays a lack of consideration for a project’s size and the cost ...
The present value of $1,000, 100 years into the future. Curves represent constant discount rates of 2%, 3%, 5%, and 7%. The time value of money refers to the fact that there is normally a greater benefit to receiving a sum of money now rather than an identical sum later.
Discount rate may refer to: Social discount rate (of consumption), the rate at which the weight given to future consumption decreases in economic models;
The subject of a social discount rate, always a source of fierce debate between economists, has become highly controversial since the publication of the Stern Review on the Economics of Climate Change. The publication exploded on the global warming scene in 2006 with its dire warning that global gross domestic product (GDP) was at future risk ...
