There is no single number that every couple should save each month. The right amount depends on what you earn together, what your fixed costs are and what you are saving for. A useful starting point is a percentage of combined take-home pay, adjusted up or down until it feels sustainable for both of you. Many couples begin with around 10 to 20 percent of take-home income as a rule of thumb, then refine it once they see their real numbers.

This guide walks through a simple way to find your own figure, split it fairly, and keep it going month after month.

Why a percentage beats a copied number

Online lists of "average" savings amounts are rarely useful, because they mix very different incomes, cities and life stages. A percentage of take-home pay scales with your situation. If your income rises, the amount rises with it; if a month is tight, you can scale it down without feeling you have failed.

Think of the number as a decision the two of you make, not a verdict on your finances. A smaller amount you actually save every month beats an ambitious target you abandon in week three.

Step 1: Find your combined take-home pay

Add what you each receive after tax and deductions. Use take-home pay, not salary, because that is the money you can really assign. If either income varies, use a conservative figure such as your lowest recent month. If your paydays fall on different dates, our guide to a couples budget with different paydays shows how to line up the cash flow.

Step 2: Cover fixed costs and a buffer first

List the bills that must be paid regardless: rent or mortgage, utilities, insurance, transport, minimum debt payments and groceries. If you have not worked out how to share these, see how to split bills fairly when you earn different amounts. What is left after fixed costs and a modest allowance for everyday spending is the pool your savings come from.

If your fixed costs already take most of your income, do not be discouraged. Start with a small, regular amount and build the habit while you look for ways to reduce costs.

Step 3: Choose a savings rate

Here is how different rates look on an example household with a combined take-home pay of 4,000 per month. These figures are illustrative, not benchmarks:

Savings rateMonthly amountPer yearBest when
5%2002,400Costs are tight and you are building the habit
10%4004,800A comfortable starting point for most budgets
15%6007,200You have a clear goal such as a deposit
20%8009,600Fixed costs are low or you have a deadline

Pick the row you can keep up in a bad month, not just a good one. You can always raise it later.

Step 4: Split the target by goal

Savings are easier to keep when each pound or dollar has a purpose. Divide your monthly amount across a few goals, for example:

A common order is a starter emergency cushion first, then sinking funds, then larger goals, while keeping any high-interest debt in view. If debt is weighing on you, paying off debt as a couple explains how to balance repayment and saving.

Step 5: Decide who contributes what

A fair split does not have to be equal. If one partner earns more, contributing the same percentage of income, rather than the same amount, usually feels fairer. Here is a worked example using the 10 percent rate on a 4,000 household:

Partner APartner BTotal
Take-home pay2,8001,2004,000
Share of income70%30%100%
Savings contribution280120400

Both partners save 10 percent of their own pay, so the burden is proportional. The same logic works for shared bills, as explained in should couples split bills 50/50?.

Save first, spend second. Schedule the transfer for the day after payday so the money moves before it can be spent.

Step 6: Make it visible and review it

Saving feels more real when you can see progress. Pick one place where both of you can check balances and goals, and look at it during a monthly check-in. The couples money date gives you a 60-minute agenda for this.

Our app, Mutual, is built for this kind of routine. It lets you track shared expenses, split costs by income, set savings goals, plan a monthly budget, get bill reminders and view reports. It is available on the App Store for iPhone.

When to adjust your savings rate

Review the number whenever your situation changes. Common triggers include:

  • A raise, a new job or a drop in income
  • A new fixed cost such as rent, childcare or a car payment
  • Reaching a goal and starting a new one
  • A month where you consistently miss the target, which may mean it was set too high

Adjusting is part of the process, not a failure. Treat the target as a living number.

Common mistakes to avoid

Couples most often stumble in the same places. Setting a target based on someone else's numbers is the first. Saving whatever is left over at month end is the second, because there is rarely anything left. Not agreeing on what counts as an emergency leads to arguments about withdrawals. And forgetting to review means a number that was right a year ago quietly stops fitting your life.

FAQ

How much should a couple save each month?

There is no universal amount. A practical starting point is a percentage of combined take-home pay, often somewhere between 10 and 20 percent, adjusted to your fixed costs and goals. Choose a rate you can keep in a tight month.

Should we save equal amounts or equal percentages?

If your incomes are similar, equal amounts are simple. If they differ, equal percentages of each partner's pay are usually fairer because the effort is proportional.

What should we save for first?

Most couples build a small emergency cushion first, then set aside money for irregular bills, then work toward larger goals such as a home deposit or a wedding.

What if we cannot save much right now?

Start with a small, regular amount, even a modest percentage. The habit matters more than the size. Review your fixed costs and raise the amount when you can.

Should savings be in a joint account?

It depends on how you handle money. Some couples use a joint account for shared goals and keep personal accounts for themselves. Our guide to joint, separate or hybrid accounts compares the options.
