Why couples use these
Most couples don't merge everything. Some share a joint account for the household and keep their own money apart; some split each bill; some earn very different amounts. These calculators show what each way means for each of you, without saying which one is right.
What you type stays with you
The calculations run in your browser. Incomes and expenses aren't sent to our server, saved, or put in the page's address.
