Household Bills & Budget Calculator

Monthly Bills & Expenses

Bills that arrive quarterly or yearly — water, insurance, council tax — divide down to a monthly figure first.

How the totals are calculated

The arithmetic is deliberately plain. Every category you fill in is added up for a monthly total, that total is multiplied by twelve for the yearly figure, and divided by the number of people in the household for the cost per person. Fourteen categories are offered — rent or mortgage, electric, gas, water and sewer, internet, phone, groceries, transport, insurance, subscriptions, household supplies, childcare, maintenance and one free slot — and a blank one contributes nothing rather than a default. Bills that arrive quarterly or yearly have to be divided down to a month before you enter them; the calculator cannot tell a quarterly water bill from a monthly one.

The pie and the bar chart are the same numbers twice: each slice is one category over the total, each bar is one category over the largest category, and both are drawn in CSS rather than by a charting library.

The comparison column is the part to read carefully. The benchmark figures — 1,500 for rent, 130 electric, 80 gas, 70 water, 75 internet, 100 phone, 600 groceries, 800 transport, 400 insurance, 60 subscriptions, 75 supplies, 500 childcare, 150 maintenance — are round monthly numbers we chose to sit in the region of typical United States household spending. They are not a lookup from a published table, they are not adjusted for your region or your household size, and a category flagged as above average means only that it is above our figure. Use them to spot which bill is the outlier in your own budget, which is a question they answer well, and not as evidence about anybody else's.

What a household budget is actually for

The average American household spent $78,535 in 2024, according to the Bureau of Labor Statistics' Consumer Expenditure Survey. Rent and groceries are obvious, but the hundreds of small recurring expenses (subscriptions, supplies, maintenance) add up quickly.

A clear household budget isn't about restriction — it's about awareness. When everyone in the household can see the full picture, decisions become collaborative rather than contentious. Should we upgrade our internet plan? Can we afford a cleaning service? These questions have clearer answers when the numbers are visible.

This calculator organizes your expenses by category and sets each one beside a round reference figure of ours, so the bill that stands out is easy to spot.

A total on its own does not tell you whether it is too much. The 50/30/20 budget calculator holds it against your take-home pay: needs — the bills above plus groceries, transport and minimum debt payments — should take no more than half, wants 30%, and savings the last 20%.

Bills are only half of what a household runs on. Once the numbers are settled, the same argument tends to move to the work: our guide to the best household chores app covers splitting that fairly, a shared grocery list app keeps the biggest variable bill under control, and our guide to tracking a shared household budget covers the monthly review itself.

Frequently Asked Questions

How do I calculate my monthly household bills?
Add every recurring cost the home itself generates, then total it: rent or mortgage, electric, gas or heating, water and sewer, internet, phone plans, insurance, and any council tax or service charge. Enter each one above and the calculator gives you the monthly total, the yearly figure, and the share per person. Bills that arrive quarterly or yearly should be divided down to a monthly number first.

What counts as a household expense?
Anything the household pays for as a household rather than as one person: housing, utilities, groceries, insurance, transport, household supplies, childcare, maintenance and shared subscriptions. Personal spending — one person's clothes, hobbies or lunches — sits outside it. Keeping that line clear is what makes calculating household expenses useful rather than depressing.

What expense categories are included?
Categories include Rent/Mortgage, Utilities (electric, gas, water, internet), Phone, Groceries, Transportation, Insurance, Subscriptions, Household Supplies, Childcare, Maintenance, and an Other line for anything else.

How much should household bills cost per month?
There is no single right figure: rent and energy swing hard by region and home size. The calculator sets each of your bills beside a round reference figure of ours — $1,500 for rent, about $355 across electric, gas, water and internet — and marks the ones above it, so you can see which bill is the outlier.

Where do the average figures come from?
They are round monthly numbers we chose to sit in the region of typical United States household spending — 1,500 for rent, 130 for electric, 600 for groceries, and so on. They are not a lookup from a published table, they carry no adjustment for your region or your household size, and a category flagged as above average means only that it is above our figure. They are good for spotting which of your own bills is the outlier, and they are not evidence about anybody else's household.

Can I split expenses between roommates?
Partly. Enter the number of household members and the calculator divides the monthly total evenly between them. It cannot mark a bill as one person's, so leave personal costs out, or use the expense split calculator for a split by income.
