Dividing bill cost in relation to incomes formula

[povertypimp]

Hi i wasn't sure where to post this does any body know of a online calculator or a formula to calculate how household bills should be paid in relation to two peoples incomes

Say person 1 has a weekly wage of £90 and person 2 has a weekly wage of £300

In pre potion to there incomes how would a weekly rent bill of £80 be split?

Does anybody know the formula for this? please help

Re: Dividing bill cost in relation to incomes formula

well ... £90 is just under 1/3 of £300, so (personally) I would say the split should be 2 to 1. It would roughly work out at £54 and £26 :tinysmile_twink_t2:

Ok
If you put the total bill into the calculator and divide it by 3, that will give you the lower amount (or what the lower income earner should be paying). Multiply this by 2 to get the higher earners figure.

As £300 (high earner) is just over 3x £90 (low earner) I have rounded down to get the lower amount and up to get the higher.
eg: £80 / 3 = 26.6666666667 this is rounded down to £26 for the low earner
26.6666666667 x 2 = 53.3333333333 this is rounded up to £54 for the high earner

Re: Dividing bill cost in relation to incomes formula

so if i was to work out another bill of £45

Using this formula the lower earner would pay £15

And the high earner £30

Is this correct?

(discreet cough) I'm going to take the unusual step of disagreeing with Kati - feel free to:caked:!

100% of available income = 90 + 300 = 390


90/390 = 3/13 or (approx) 23.077% (call it 23)
300/390 = 10/13 or 76.9% (call it 77)

so for every 100 the person earning 90 pays 23 and the person earning 300 pays 77

for ease of calculation the split is more 1/4 to 3/4

In the case of 45, 23% of 45 is 10.35
77% of 45 is 34.65

do feel free to correct if wrong:nerd:!
