Couples Household Cost Splitter | Shared Bills & Expenses Excel Spreadsheet UK

Know what each of you should contribute, what each of you actually paid, and where you stand at the end of the month.

The MoneySavvyUK Couples Household Cost Splitter is a simple Excel workbook for couples and partners who share household costs but don't necessarily split everything in exactly the same way.

Choose how you want to split each cost

✓ Equal split — 50/50

✓ Income-proportional split — based on the monthly take-home figures you enter

✓ Custom split — such as 60/40, 70/30 or another percentage you choose

Different bills can use different methods. For example, you could split one household bill equally while using a custom percentage for another.

Keep track of shared household costs

Use the workbook to organise things such as:

✓ Rent or mortgage contributions

✓ Council Tax / Rates

✓ Gas and electricity

✓ Water

✓ Broadband

✓ Household subscriptions

✓ Groceries

✓ Household purchases

✓ Other shared expenses

See who actually paid

Splitting an expense and paying for it are two different things.

The workbook records both:

What each partner's calculated share is

and

What each partner actually paid

The Monthly Settlement then shows the difference so you can see whether one person is ahead or behind.

If the entered payments don't reconcile with the expense total, the workbook displays CHECK INPUTS instead of silently producing a misleading settlement figure.

Plan regular household bills

The Joint Account Planner shows each partner's planned contribution towards the active recurring bills you've entered.

You don't need a joint bank account to use it — it is simply a planning tool.

Please note

Designed for Microsoft Excel (.xlsx).

This workbook is for household organisation and estimation only. It does not decide what is fair, create or change legal ownership, determine liability for rent, mortgage, Council Tax/Rates, debts or other bills, calculate benefits or tax, or create a legal agreement.

A 50/50, income-proportional or custom split is simply a planning choice entered by the users. Legal responsibility depends on the relevant accounts, contracts and individual circumstances.
