1. Combine Your Paychecks Into One Shared Plan

You know that feeling when you both get paid and somehow still end up broke by Friday?

That’s because without a shared plan, two paychecks turn into double the chaos.

You can avoid that by treating both paydays like one team effort.

Here’s what it looks like when done right:

• Create one joint budget that covers shared bills like rent, groceries, and utilities.
  
• Keep transparency by using one shared spreadsheet or app that both of you can see.
  
• Plan for big goals like vacations or saving for a home. Together.
  

👉 Here's How You'll Do It: Sit down once a month, write down every shared bill, and agree on how much each of you contributes to the pot.

Make It Easy: Consider using a large budget planner notebook to track both incomes and shared goals together.

2. Split Expenses Fairly Based on Income

Splitting 50/50 sounds fair. Until one of you makes half the income.

If one partner earns less, that “equal split” can cause resentment fast.

Instead, split based on percentages so it’s fair and stress-free.

Here’s how to make it simple:

• Calculate what each earns, then split shared costs based on that ratio.
  
• Adjust every few months as income changes or new bills pop up.
  
• Be transparent. Money secrets create tension faster than dirty dishes.
  

👉 Here's How You'll Do It: Add both incomes, divide each by the total, and pay that percentage toward shared bills.

Make It Easy: Use a simple desktop calculator or budgeting spreadsheet to keep the math easy and visual.

3. Keep Separate Fun Money Accounts

You can love your partner and still not want them questioning your Starbucks run.

That’s where separate “fun money” accounts save both your budget and your sanity.

Each person gets their own small allowance. No judgment attached.

Here’s what it helps with:

• Freedom to spend on personal things guilt-free.
  
• Fewer arguments over “you bought what?” moments.
  
• More harmony when both have equal financial breathing room.
  

👉 Here's How You'll Do It: Decide on a monthly amount you both can freely spend and transfer it to separate debit cards.

4. Save Automatically From Both Incomes

Saving manually is basically asking to forget.

When you automate it, you save money without even thinking about it.

The goal is to make saving happen before spending does.

Here’s how you can set it up:

• Set automatic transfers from both paychecks to a joint savings account.
  
• Pick a realistic amount that doesn’t leave you struggling mid-month.
  
• Watch your savings grow without a single “we forgot to save” moment.
  

👉 Here's How You'll Do It: Set up recurring transfers every payday into one shared high-yield savings account.

Make It Easy: Open a Betterment Cash Reserve Account to automate savings and earn interest on every dollar.

5. Set Shared Financial Goals and Review Monthly

You can’t reach a goal you never talk about.

That’s why monthly money meetings matter more than date nights (okay, almost).

When you review goals together, you stay aligned and motivated.

Here’s how to make it a fun routine:

• Set small, realistic goals like saving $100 a week or paying off one card.
  
• Celebrate wins, even small ones, with something simple like takeout or a movie night.
  
• Adjust as needed because life (and expenses) change fast.
  

👉 Here's How You'll Do It: Schedule a 30-minute “money check-in” on the same date every month and go over everything together.

Make It Easy: Use a monthly dry-erase board to track goals where you both can see it.
