<prompt> Human: Hi Reddit,So I am looking for a little bit of advice on the best ways to split finances in a new relationship. My boyfriend and I have been dating for around 4 months but have known each other for almost 4 years. His lease is up next month and we have both been talking about moving in together. I am basically wondering what is a good price to ask for rent. To be honest, I dont NEED the money. I currently think I am saving pretty well and I have a good chunk of money saved up too. Also, in my career I have been moving up fairly quickly since I graduated college and I am expecting another promotion within the next couple months. Anyways, I was thinking about charging around 150month since that would cover the added expenses of him living there groceries, electricity increase, etc.. I was discussing this with my parents and they were saying I should charge him what I would a roommate 400-500 a month. If it matters, he makes about the same amount of money as me, but he does currently have more expenses than I do, due to the fact that hes been trying to get his business up and running the past couple months. I would say he only has around 500 in expendable income each month. Currently here is what my budget looks like:Take Home Pay: 2,700mo. after 5 match into 401KMortgage: 700 15 Year TermElectric:100Cable:050Internet:050Gasoline: 150Home Insurance: 60Car Insurance: 100Gas: 100Groceries: 175Entertainment: 50Personal: 25Clothing: 200Roth IRA: 300Vacation Fund: 100Misc. Spending: 40Savings: 500My Property Taxes Come to Around 1,100YearI also do taxes during tax season, but that income is pretty variable, I would say on average that increases my saving by about 2,500year, I use that to max out my Roth contributions and put the rest into a regular savings account. I also get a bonus of around 2.5 a year which also goes into my regular savings account.Any advice would be great! Also, any advice on my budget would be great as well! Thanks everyone!!Oh, one last thing to include. We usually go out once a week or so which costs around 20-25 a time and he does pay almost always I offer he just refuses to let me pay.  <response>: My advice is not to merge finances with someone until you both are willing to commit to each other for the rest of your lives and have reasonable assurance that such a commitment is likely to be successful. Divorce tends to be messy and destructive. Breakups with merged finances can go even worse, as without divorce you lack the sort of protections divorce can provide to ensure that the dissolution of shared finances ends up equitable.So, I would split all shared expenses 5050 and pay fully for any individual expenses. If you break up then there is no harm no foul. You both will have carried your fair share.
