**Compound Interest: **

**Compound Interest:**

A user can calculate the future value of the investment using the below formula in excel

Formula:P*(1+r)^n

** Argument: **P: is the principal amount invested

r: is the interest which can be annually, bi-annually, quarterly or monthly

n: is the period of investment is the number of periods over which the investment is made

** Example:** John invested $200 for 2 years at an annual interest rate of 5%, the future value of this investment can be calculated by typing the following formula into any Excel cell

**which gives the result**

**=200*(1+5%)^2****.**

**220.5****Depreciation of Asset:**

**Depreciation of Asset:**

** **In Excel user can calculate the depreciation of an asset in the given time period. There are 5 different methods in excel to calculate the depreciation of the asset:

**Straight Line Depreciation (SLN): **

**Straight Line Depreciation (SLN):**

This is the most basic method to calculate the depreciation. This method depreciates the asset value by a fixed amount over the period of time.

** Definition:** SLN function in Excel can be used to calculate straight-line depreciation in excel

FormulaSLN(cost, salvage, life)

__ Example: __John’s asset cost is $5,000 and has a residual value of $100 after 10 years, we can calculate the annual straight-line depreciation of the asset as

**=SLN(5000, 100, 10 ) = $490**

**Decline Balance Depreciation (DB): **

**Decline Balance Depreciation (DB):**

This is a compounded depreciation method. In this method, the value of the asset is reduced by a fixed percentage over the period of time.

** Definition: **DB function in excel can be used to calculate decline balance depreciation.

Formula:DB(cost, salvage, life, period, [month])

__ Example: __John’s asset cost is $5,000 and has a residual value of $100 after 10 years, we can calculate the declining balance depreciation of the asset during year 1 as follow

**=DB(5000, 100, 10, 1) = $1620**

**Double Decline Balance Depreciation (DDB): **

**Double Decline Balance Depreciation (DDB):**

In this method, the cost of an asset is being charged at the double rate of straight line depreciation. Therefore, in this method the depreciation is the highest in the first period and less in successive periods.

__Definition:__ DDB function in Excel can be used to calculate decline balance depreciation.

Formula:DDB(cost, salvage, life, period, [factor])

__ Example: __John’s asset cost is $5,000 and has a residual value of $100 after 10 years, we can calculate the declining balance depreciation of the asset during year 1 as follow

**=DB(5000, 100, 10, 1) = $1000**

**Variable Declining Balance (VDB):**

**Variable Declining Balance (VDB):**

** **__ Definition:__ This function returns the depreciation of an asset for any period specified by the user, including partial periods, using the double-declining balance method or some other method.

Formula:VDB(cost, salvage, life, start_period, end_period, [factor], [no_switch)

** Example: **John’s asset cost is $5,000 and has a residual value of $100 after 10 years, we can calculate the declining balance depreciation of the asset during year 1 as follow

**=VDB(5000, 100, 10, 1, 3) = $1440**

**Sum-of-Years’ Digits Depreciation(SYD): **

**Sum-of-Years’ Digits Depreciation(SYD):**

This is also an accelerated depreciation method. Using this method annual depreciation is being determined by multiplying the depreciable cost by a schedule of fractions.

** Definition:** SYD function in Excel can be used to calculate Sum-of-Years’ Digits Depreciation

Formula:SYD(cost, salvage, life, per)

__ Example: __John’s asset cost is $5,000 and has a residual value of $100 after 10 years, we can calculate the declining balance depreciation of the asset during year 1 as follow

**=SYD(5000, 100, 10, 1) = $892**

**XNPV:**

**XNPV:**

** **Using XNPV functions a user can calculate the net present value for a schedule of cash flows that is not necessarily periodic.

Formula:XNPV(discount_rate,cash_flows, dates)

** Definition: **discount_rate: is the rate to apply on cash flow

cash_flows: is series of cash flows that corresponds to a schedule of payments in dates

dates: are the schedule payment dates related to cash flow payments.

**XIRR: **

**XIRR:**

It returns the internal rate of return for a schedule of cash flows that is not necessarily periodic.

Formula:XNPV(cash_flows, dates,[guess])

** Definition:** cash_flows: is series of cash flows that corresponds to a schedule of payments in dates.

dates: are the schedule payment dates related to cash flow payments.

guess: It is an optional parameter. It is a number that user guess is close to the result of XIRR.

**IRR:**

**IRR:**

** **It returns the internal rate of return for a schedule of cash flows which are periodic.

Formula:XNPV(cash_flows, [guess])

__Argument:__ cash_flows: is series of cash flows that corresponds to a schedule of payments in periodic dates

guess: It is an optional parameter. It is a number that user guess is close to the result of IRR.

**MIRR:**

**MIRR:**

** **The user can also use the MIRR function in case of periodic cash flows. It returns the modified internal rate of return for a series of periodic cash flows. MIRR considers both the cost of the investment and the interest received on reinvestment of cash.

Formula:MIRR(cash_flows, finance_rate, reinvest_rate)

** Definition:** cash_flows: is series of cash flows that corresponds to a schedule of payments in dates

finance_rate: the rate of borrowing money

reinvest_rate: interest rate received on the cash flows after reinvesting it
