How do I split my week van rental bill fairly if 6 people used for 7 days and 1 person used for 5 days?

Question

My van rental is $532.69 for 7 days. 6 of us are paying for 7 days use and 1 is paying for 5 days use since he came later on our trip. I can split the cost evenly between the 7 people but I don't want to over charge my friend who wasn't there for the first two days. Is there a formula I can use? I just want to be fair. Thanks for your help everyone.

Answer 1

Think of it in man-days. For two days, you had 6 people and for 5 days you had 7. That is 12 + 35 man days = 47. Each person pays a 47th share for each of the days he used the van.

I make that a little over $11.33 per person per day.

Answer 2

divide the total by the numer of days each person used van, Divide that number into the total amount
multiply the number of days by that per diem/person cost.

thus:

7days x six people is 42 people days, plus 5 days for your odd friend, 47 peopledays total.

each person pays 1/47 of he bill for each day used.

$532.69 divided by 47 equals 11.34 per day per person

6 of you should pay $79.38 each ($476.28 total)

The five day rider should pay $56.65.

Note, numbers are rounded up for convenience, so will be a little on the high side.

Also, if one person drove every day, their cost should be defrayed by the others, as driving is a pain in the butt, and the driver may have had to bear all the insurance and rental liability as well.

Answer 3

the vehicle was used by
1) 6 people * 7 days = 42 person days
2) 1 person * 5 days = 5 person days

total 47 person days.

for each person days, the cost of usage is -
$532.69/47 = $11.3338.

So each person who used for 7 days would pay
$11.3338 * 7 = $79.34

one who used for 5 days would pay-
$11.3338 * 5 = $56.66

Answer 4

total man days = 6x7 + 1x5 = 42 + 5 = 47
charge late friend 5/47 of total
charge everyone else 7/47 of total

Answer 5

6 people paying for 7 days of use = 532.69/7 =charge per day

charge per day + 7 for 6 of your friends and charge per day + 5 for your other friend

Answer 6

total mandays=6*7+1*5=47
total bill=532.69
so per manday=11.33
so the bill for theman who use for 5 days=$11.33*5=$56.65
for each one of the 6 people used for 7 days=11.33*7=$79.34
