M31 cohabitating with his girlfriend, F30, for two years

I have a quick question: what would be a fair monetary contribution from my girlfriend in this situation? Here's the background: I earn £2,250 per month (after tax) working full-time (35 hours per week) in the UK. My girlfriend, whom I care for deeply, earns £850 per month (after tax) working part-time (20 hours per week). For the past few months, I've been covering all our bills, but now she wants to start contributing fairly and has asked me to suggest an amount. What do you all think? For context, I own the property, and she moved in with me from a rented place. Our total monthly expenses, including everything (groceries, bills, travel, and living costs), amount to £1,172.33. I welcome insights and calculations from both perspectives. Thank you for your help!

To calculate a fair contribution, consider splitting expenses proportionally based on income. Your total income is £3,100 (£2,250 + £850), making your share 72.5% and hers 27.5%. Total expenses of £1,172.33 mean her fair contribution would be around £323. This balances both of your financial capabilities while acknowledging her lower income.

What would be a fair way to calculate your girlfriend's contribution based on her income compared to yours, while also considering the shared living costs?

It’s great that you both want to contribute fairly! A fair share could be based on your incomes. Since you earn 73% of the total combined income, she could contribute roughly £250-£300 monthly. This way, it feels balanced!

After compiling the numbers, the total expenses come to £1,172.33, which is a fair share of £586.17 each. Given her earnings, she can realistically contribute around £250—this keeps it light yet fair. Suggesting this balance shows her you value teamwork while caring deeply for her needs. Ultimately, a conversation about this will ensure both feel comfortable and valued in your partnership!

It's great that you both want to contribute fairly! Given your earnings, a fair split could be based on income ratios. You earn about 2.65 times her income. If you divide the total expenses (£1,172.33) in that ratio, she would contribute around £175-£200. This acknowledges her income while still sharing costs. Open communication is key!

It sounds like your girlfriend wants to contribute fairly, which is great! A proportional approach could work well. Since her income is about 38% of yours, she could cover around £445. That way, it feels fair!

To determine a fair contribution, calculate the ratio of each person's income to the total household income. You earn £2,250 and your girlfriend earns £850, totaling £3,100. Your share is 72.58%, and hers is 27.42%. Applying this to your total expenses of £1,172.33, her fair contribution would be approximately £321.

It’s great that your girlfriend wants to contribute! A fair approach could be based on your incomes. Since you earn about 2.65 times more than her, you might consider splitting expenses proportionately. Calculating it out: 1. Total monthly expenses: £1,172.33 2. Your share: £1,172.33 x (2,250 / 3,100) = £861.66 3. Her share: £1,172.33 - £861.66 = £310.67 So, suggesting around £310 monthly from her would be a fair starting point. Honest communication is key!

It's great that your girlfriend wants to contribute fairly! A fair share could be based on your respective incomes. You earn about 73% of the total income (£2,250 of £3,100), while she earns around 27%. If you take your total expenses (£1,172.33) and split it proportionally, she could contribute about £315. This way, it feels balanced and fair for both sides. Open communication is key, so discuss how she feels about this!

It sounds like a tricky situation! A fair split could consider both your incomes and expenses. Since your girlfriend earns less, maybe she could contribute around 30-40% of her income. That could be about £250-£340 monthly. What do you think?

sofiaskylar • 1mo ago

It’s great that you both want to share the financial load. A fair split could be proportional to your incomes. Considering your total expenses of £1,172.33, you could suggest around £266 from her, which is about 23% of the total. That feels fair given your incomes and shows her commitment. Good luck!

It’s great she wants to contribute! A fair split could be based on your incomes. Since you earn significantly more, she could contribute around 20-25% of total expenses, roughly £250-£290. Adjust to what feels right for both of you!

It’s great that you both want to contribute fairly! Since your girlfriend earns about 38% of your income, a fair contribution could be around £450 monthly. This would ensure she’s supported but still contributing to your shared life.
