Budgeting for couples, with room for both of you

The real problem

Money is one of the things couples argue about most, and the arguments are rarely about arithmetic. They’re about surprises: a charge one person didn’t know about, a bill both thought the other had paid, a savings goal that only one of you was counting on.

Most couples also don’t fit neatly into “everything joint” or “everything separate”. A common arrangement is a shared pot for the household, plus some money each person can spend without explaining it. That’s sensible. It’s just awkward to track with one shared login, or with two separate apps that never meet.

A practical approach: yours, mine and ours

A simple structure that works for many couples:

• One joint account for shared costs: housing, groceries, utilities, insurance, the car.
• Each person keeps a personal account for their own spending, no questions asked.
• Contributions are agreed in advance, either equal or in proportion to income.

Here’s a worked example with round numbers. Alex takes home $4,000 a month and Sam takes home $2,000. Shared costs come to $3,600. If they split in proportion to income, Alex earns two thirds of the total, so Alex puts in $2,400 and Sam $1,200. Each is left with a third of their pay ($1,600 and $800) for their own spending and saving.

An equal split ($1,800 each) would leave Sam with only $200, which is why many couples with different incomes prefer the proportional version. Neither is right for everyone; splitting bills on different incomes walks through the trade-offs.

Whatever you choose, two habits help more than any app: a short monthly money conversation, and a shared view of what’s coming up, so bills and big purchases aren’t surprises.

How Kemback helps

Kemback is built around a household, so a couple works from the same budget without sharing a password.

• Your own sign-ins. Invite your partner by email. Each of you signs in separately, with passkeys or two-step sign-in if you want them.
• Shared and private accounts. Mark the joint account and joint cards as shared. Keep a personal account private: its transactions are visible only to its owner, and its spending counts only in that person’s view of the budget.
• One budget, two styles. Use category budgets (a monthly plan per category) or envelope budgets (give every dollar in the joint account a job). You can switch at any time without losing anything, which is handy if one of you likes envelopes and the other doesn’t.
• No surprises on bills. The bills calendar shows what’s due and when, and Kemback warns you when a bill or subscription goes up. Alerts for bills due, low balance and large purchases arrive by email, in the app or on iPhone.
• Safe to spend. See what’s left in the shared account after upcoming bills, and a 90-day projected balance.
• Goals you both can see. Fund a holiday or a house deposit from an account or an envelope, with the monthly amount needed to get there.
• A record of who changed what. The household’s activity log is tamper-evident, so a changed category or deleted transaction isn’t a mystery.

The Free plan includes a household of two, with no time limit.

What it doesn’t do

Kemback doesn’t link to your banks automatically yet; you import files you download from your bank (OFX, QFX, QIF or CSV). Automatic bank sync through Plaid is planned for the Plus plan, which isn’t on sale yet. There’s no bill pay and no way to move money between you; Kemback tracks money, it doesn’t hold it.

It also won’t settle the conversation for you. If you’re combining finances after a marriage, or untangling them, a fee-only financial planner can help with the bigger decisions. For the first steps, read combining finances after marriage and joint, separate or both.

Questions

Can my partner and I use Kemback for free?

Yes. The Free plan includes a household of two, with no time limit. Each of you signs in with your own account and sees the same household budget.

Can I keep an account private from my partner?

Yes. Any account can be private to its owner. Its transactions stay out of your partner's view, and its spending counts only in your own view of the budget, so the shared budget stays about shared money.

Do we have to share a password?

No. Each person has their own sign-in, with passkeys and two-step sign-in available. You invite your partner by email and choose their role.

Can one of us only look, not edit?

Yes. Roles are owner, editor, viewer and advisor. A viewer can see the shared budget and accounts but can't change them.

Does Kemback connect to our banks automatically?

Not yet. Today you import OFX, QFX, QIF or CSV files from any bank. Automatic bank sync through Plaid is planned for the Plus plan, which isn't on sale yet.
