## The short version

- Start from real data for the last three months, not from estimates.
- Split spending into fixed, variable and yearly, and set a monthly saving before variable spending.
- Pick a joint-account model that suits both of you and that you can talk about calmly.
- Half an hour a month is worth more than a perfect budget abandoned after two weeks.
- You can download a CSV template and make tracking automatic with a read-only connection.

Most families do not fail at budgeting for lack of willpower, but because the budget does not match life: it rests on guesses, demands tedious routine work, or is built by one partner without the other. This guide is built to survive a busy week: a simple seven-step method, a downloadable template, three models for running a joint account, and a way to make tracking automatic.

## Seven steps to a budget that lasts

1. **Set one goal** — A budget without a goal is a list of limits. Pick something concrete: an emergency fund, a holiday, paying down a debt or a large purchase. The goal gives every cut a purpose.
2. **Gather three months of data** — Export transactions from your account and cards for the last three months. Real data beats memory, because people underestimate variable spending.
3. **Split into three groups** — Fixed (rent, property tax, insurance, loans), variable (groceries, transport, leisure) and yearly (car insurance, holidays, a trip). Divide the yearly ones by 12 and set the amount aside every month.
4. **Work out true net income** — Count only what lands in the account, after deductions. Irregular income is counted at a conservative average of recent months.
5. **Pay yourself first** — Set a regular monthly saving and transfer it on payday, before variable spending. What is left is the budget for day-to-day costs.
6. **Set a cap for each variable category** — One cap for each large variable category (groceries, leisure, transport). Five categories are enough, not twenty.
7. **Review once a month** — Set a fixed half hour, for example at month end, and compare plan with actual. Adjust the budget to your life, not your life to the budget.

## A downloadable template

We made a simple CSV template: ready categories, columns for plan and actual, and a calculated difference. You can open it in Excel, Google Sheets or any spreadsheet program. The template is empty, and every number in it is yours.

**Family budget template** A CSV file in English with fixed, variable, saving and yearly categories, and a calculated difference. [Download the template (CSV)](https://www.shavve.io/downloads/family-budget-template-en.csv)

> **Tip — How to use it**
> Fill in net income at the bottom, then a monthly plan for each category. At month end fill the “Actual” column and check the difference. If the planned total is higher than income, cut variable categories, not saving.

## How to run a joint account: three models

Deciding how to split money between partners is sometimes the hardest part of a budget. There is no single right model. What matters is that the model is agreed, transparent and changeable.

| Model | How it works | Advantage | Drawback |
| --- | --- | --- | --- |
| Everything joint | All income goes into one account and everything is paid from it | Simple and transparent, one picture | Less personal autonomy, and friction over personal spending |
| Joint plus personal | A joint account for household costs, and each keeps a fixed amount for themselves | A balance between transparency and freedom | You must agree on the amounts and on what counts as “joint” |
| Proportional to income | Each contributes to joint costs in proportion to their share of income | Fair when incomes differ a lot | Needs calculation and updating when incomes change |

*Split income into needs, wants and saving (on the website: an interactive calculator)*

If you want a starting point, the [50/30/20 method, Israeli edition](https://www.shavve.io/en/articles/budget-method-50-30-20) suggests an initial split, and you can try it in the [50/30/20 calculator](https://www.shavve.io/en/tools/budget-50-30-20-calculator). It is a starting point, not an iron rule: a family with high rent will adapt it.

## Yearly expenses and an emergency fund

Two categories sink many budgets: a yearly expense that arrives suddenly, and an unexpected failure. The first is handled by a fixed monthly set-aside: add up the yearly costs (car insurance, holidays, classes, a trip), divide by 12 and set that aside. The second is handled by an [emergency fund](https://www.shavve.io/en/articles/emergency-fund-guide): money that is available and does not come from what you planned to spend. You can size the fund in the [emergency fund calculator](https://www.shavve.io/en/tools/emergency-fund-calculator), and the pace to a savings target in the [savings goal calculator](https://www.shavve.io/en/tools/savings-goal-calculator).

## The half-hour monthly review

**What to check at the end of each month**

- [ ] Did net income match the plan?
- [ ] Which categories did we overshoot, and why: a one-off or an unrealistic estimate?
- [ ] Was the monthly saving transferred?
- [ ] Is there a recurring charge or subscription we can cancel?
- [ ] What is the next yearly expense, and is the set-aside enough?
- [ ] What do we change next month?

## How to make tracking automatic

The hard part of a budget is not the plan but the tracking: typing each expense or exporting transactions every month. You can reduce the work in three levels.

| Level | What you do | How much work |
| --- | --- | --- |
| Manual | Export transactions from the bank and the card once a month and paste them into the template | Half an hour to an hour a month |
| Semi-automatic | The bank or card company sends alerts and the monthly summary, and you update the template | About 15 minutes a month |
| Automatic | A read-only connection pulls transactions, categorises spending and shows budget against actual | A short check, no typing |

In an automatic open-banking connection you let a licensed app read data, without handing over your bank password, and you can revoke at any time. What matters in choosing is covered in [How to choose a money management app](https://www.shavve.io/en/articles/best-money-management-apps-israel) and [Which apps are licensed](https://www.shavve.io/en/articles/open-banking-licensed-apps-israel). The Shavve app includes a household: partners see a shared picture, each approves what to share, and duplicate transactions in joint accounts are neutralised.

## An illustration: what a split can look like

The example below is an imaginary family, and its numbers are made up purely to show the arithmetic. They are not data about families in Israel and not a recommendation of any particular percentages. Suppose a net income of ₪20,000 a month.

*A made-up example, for illustration only*

| Group | Planned per month (₪) | Share of income |
| --- | --- | --- |
| Fixed expenses | 10,000 | 50% |
| Variable expenses | 6,000 | 30% |
| Set-aside for yearly expenses | 1,000 | 5% |
| Monthly saving | 3,000 | 15% |
| Total | 20,000 | 100% |

If variable spending turns out to be ₪6,800 at month end, the overshoot is ₪800, and it should be covered from another category or next month, not from saving. The percentages in the table are an example: a family with high rent will show a larger share of fixed costs.

## How to start the money conversation as a couple

- Set a time in advance, not in the middle of an argument about one charge.
- Start from the shared goal and not from the other person's spending.
- Show the data for the last three months, so the talk is about facts.
- Agree on a personal amount that can be spent without reporting.
- Set a date to review, and agree that the model can change.

## A budget when income is irregular

If one of you is self-employed or earns commission, planning around a good month will leave a deficit in a weak one. Instead, base the budget on the reasonably low income of the last year, and set the surplus of good months aside in a separate account that tops up weak months. That way fixed costs are always covered and swings in income do not sink the plan.

## What to do when the budget does not add up

1. **Check fixed costs first** — That is where the biggest saving is, and one change repeats every month: insurance, communication plans, subscriptions and loans.
2. **Then variable ones** — Cut one category at a time, not all at once, so the change lasts.
3. **Check income** — See whether any income is unused, such as benefits, tax refunds or more working hours.
4. **Protect the saving** — Even a small fixed amount beats cancelling saving altogether, because the habit matters more than the sum at first.

## What goes in which category

One thing that confuses people at the start is classification. A simple rule: if an expense is roughly the same every month and is collected automatically, it is fixed. If it depends on your behaviour this month, it is variable. If it arrives once every few months, it is yearly.

| Type | Examples | How to plan |
| --- | --- | --- |
| Fixed | Rent or mortgage, property tax, monthly insurance, a communication plan, subscriptions, a loan repayment | A known amount, and check whether it can be lowered |
| Variable | Groceries, fuel, eating out, clothing, leisure, small gifts | A monthly cap based on the average of three months |
| Yearly | Annual car insurance, holidays, classes and camps, a trip, a large repair | Divide by 12 and set aside every month |
| Saving | A regular monthly saving, an emergency fund | Transferred on payday, before variable spending |

## Children and the budget

Children and teenagers learn at home. You can involve them in age-appropriate decisions, such as a budget for a family trip, and give them a fixed allowance they manage themselves, including deciding what to do when the money runs out. There is no need to show them the whole family financial picture, but to teach principles: set aside before spending, compare before buying and wait before a large purchase.

## Common family-budget mistakes

- Building the budget from memory instead of three months of data.
- Defining many categories and tiring of it after two weeks.
- Forgetting yearly expenses, which then sink the month they arrive.
- Leaving saving out of the plan and making it whatever is left.
- One partner builds the budget alone and the other has no ownership of it.
- Chasing a perfect budget instead of one you can keep.

## What to do with a surplus or a deficit at month end

Every month ends in one of two ways. Decide in advance what you do in each, so the budget does not stay just a spreadsheet.

- A surplus: move it the same day to a fixed goal, in the order you set: emergency fund first, then expensive debt, then long-term saving. Money left in the current account tends to disappear.
- A small deficit: do not cover it with credit. Find the category that went over, and lower its ceiling next month or trim another category to match.
- A deficit three months in a row: this is no longer an exception but a budget that does not fit the income. Review the fixed costs, and talk to the bank or a professional before the debt grows.

**How do you build a family budget?**
Collect three months of real data, split spending into fixed, variable and yearly, work out net income, set a regular monthly saving, cap the variable categories and review once a month.

**How many categories does a budget need?**
A few large ones are enough: fixed costs, groceries, transport, leisure and saving. Many categories are tedious and usually lead people to abandon the budget.

**How do couples split expenses?**
There are three common models: everything joint, joint with a personal amount for each, or a split in proportion to income. The choice should be agreed and transparent.

**Can I download a budget template?**
Yes. The page has a CSV template in Hebrew and English with ready categories and a calculated difference column. It opens in Excel and Google Sheets.

**How do I automate budget tracking?**
With a read-only connection to your bank account and credit cards through an app that holds a financial-information-service licence. Check the licence in the official list and make sure you can revoke at any time.
