10. LOGICAL FUNCTIONS Is value A equal to value B (A=B) Is A greater than B (A>B) Is A less than B (A<B) Is A greater than or equal to B (A>=B) Is A less than or equal to B (A<=B) Is A not equal to B (A<>B) These are called Logical or Boolean operators because there can only be two possible answers in any given case - TRUE or FALSE.

11. LOGICAL ‘IF’ FUNCTIONS Most common logical function is the IF function. The function returns one value when a condition is met (TRUE) or returns another value when condition is not met (FALSE). =IF(Logical_Test, Value 1, Value 2)

12. LOGICAL ‘IF’ FUNCTIONS

13. The RANK function returns the rank of a number in a list of numbers. Return value is a number that indicates rank. = RANK (number, range, [order]) – number - The number to rank. – Range – Group of cells that contains the numbers to rank against. – Order - [optional] Whether to rank in ascending or descending order. RANK FUNCTION

15. The Excel PMT (payment) Function is a really simple to use but highly useful Financial Function used to calculate the repayment amount on a loan. Suppose you purchased a car and the details – Total Cost: 30,000 $ – Initial Down payment: 4,000 $ – Rate of Interest (Annual): 6% – No: of years: 5 FINANCIAL FUNCTIONS - THE PMT

16. Need to know how much I need to pay per month…? =PMT (rate, nper, pv, [fv]. [type]) – Rate (Annual): 6 % and No: of years: 5 – But the rate and nper is per month in the syntax So Rate = 6% divided by 12 = 0.5% per month No: of years (in months) = 5 x 12 = 60 months. FINANCIAL FUNCTIONS - THE PMT
