What the defaults give
A $7,000 monthly income against $5,100 of listed expenses leaves $1,900.
That is a 27.1% saving rate, with housing taking $2,000, or 28.6% of income.
The formula
Total expenses = housing + food + transport + utilities + childcare + other
Balance = income − total expenses
Saving rate = balance ÷ income × 100
Six lines, one month. Every entry is a monthly amount in the same currency, so the six can be added without any conversion. The balance is what is left before deliberate saving, investing or debt overpayment, so it is a cash surplus rather than money already put aside.
Worked examples
Defaults → 2,000 + 800 + 500 + 300 + 1,000 + 500 = 5,100; 7,000 − 5,100 = 1,900 (27.1%)
Same costs, income 5,500 → balance 400 (7.3%)
Childcare 1,500 instead of 1,000, income 7,000 → expenses 5,600, balance 1,400 (20.0%)
Income 4,800 with the same costs → balance −300, a deficit
Housing 2,500, everything else unchanged → expenses 5,600, balance 1,400
Reading the ratios
Housing at 28.6% of income is just under the common 30% affordability guide. Childcare at 14.3% is the second-largest line and the one most likely to swing a family budget, because it ends abruptly when a child starts school and can jump with a second child.
A 27% saving rate is strong for a household with childcare costs. If the surplus is not moved out of the current account, though, it tends to be absorbed by irregular spending — the budget shows capacity, not behaviour.
What the six lines leave out
Income tax and social contributions are assumed to be already deducted. Debt repayments, insurance, school fees, subscriptions, holidays, car maintenance and irregular home repairs are not separate lines, so a budget that balances here can still run short in a month with a boiler failure.
Use gross or net income consistently. Mixing a gross salary with net expenses overstates the surplus by the tax bill, which is the most common way this kind of budget flatters a household.
Frequently Asked Questions
How much is left from a $7,000 income with $5,100 of expenses?
$1,900, which is a 27.1% saving rate. Housing accounts for $2,000, or 28.6% of income.
Should I enter gross or net income?
Net income, after tax and social contributions, because the expense lines are amounts you actually pay. A $7,000 gross salary with $1,000 of tax and contributions leaves $6,000 to budget, not $7,000.
Why is my balance negative?
The six listed expenses exceed income. The calculator reports the deficit as a negative balance and a negative saving rate rather than hiding it.
Does this include debt payments?
No. Loan, card and mortgage principal payments are not one of the six lines, so add them to "other" or treat the balance as money available for debt reduction.
What is a good saving rate?
There is no universal number, but 15–20% of net income is a common target. A household with high childcare costs may run lower for a few years and catch up later.
