A couple's five numbers

If you don't know how much the other one makes, you're not really a couple: you're roommates. And no, you don't have to show everything. You need five numbers. Blue's and Orange's are filled in; swap in yours.

// first number

What each of you takes home

What lands in your account each month, after taxes.

Between the two of you: $3,500 a month

// second number

The fixed household costs

Rent or mortgage, electricity, water, internet, groceries… what the home costs each month.

Each of you puts in the same share of what you take home: whoever earns more puts in more.

// blue
$900

60% of the home

// orange
$600

40% of the home

// third number · the one nobody mentions

The payments each of you already had

A car loan, another loan, support payments… What each of you was already paying before you were a couple. It goes on its own: it doesn't change how the home is split.

// fourth number

What each of you has left free

What you take home, minus your share of the home, minus what you already had.

// blue
$1,200

$2,100 − $900 for the home

// orange
$600

$1,400 − $600 for the home − $200 existing

Not $800: $600

// fifth number

A savings goal with a date

How much you want to put together and how soon. With a date, the goal turns into a number per month.

// how to talk about it without fighting
  1. Once a month. Twenty minutes, not one more.
  2. One sheet of paper with these five boxes: what each of you takes home, the household costs, existing payments, what's left free and the savings.
  3. Compare it with last month. Nothing more.

Roommates split bills. A couple shares the five numbers.
