50/30/20 budget calculator
What this tool tells you
This tool splits monthly take-home income into three boxes, needs, wants and saving, and shows how many shekels fall into each. The default is the 50/30/20 rule, but you can pick another split or move the percentages yourself.

How it is calculated
The calculation is simple percentages: the amount in each box is your take-home income times the percentage chosen for it. The saving percentage is always what remains after needs and wants, so the three boxes always add up to 100%.
amount = income × percent / 100
saving % = 100 − needs % − wants %
income is the monthly take-home income you entered and percent is the share chosen for that box.
Assumptions
- Income means monthly take-home pay, after deductions.
- The ready-made splits in the tool are 50/30/20, 60/20/20 and 70/20/10, and you can fine-tune the percentages by hand.
- The tool does not classify your spending for you. What counts as a need and what counts as a want is your decision.
- The wants percentage cannot exceed what is left after the needs percentage.
How to read the result
- Compare the amount in the needs box with your actual fixed costs: rent or mortgage, bills, food, transport and insurance.
- If your needs are already above the split, that is not a failure but a common situation. Try 60/20/20 or 70/20/10, or start with a small saving and raise it gradually.
- The third box is saving. Pension and study-fund deposits taken from your payslip are saving too, so pick one basis, net or gross, to avoid counting them twice.
Limits of this tool
50/30/20 is a rule of thumb, not a law, and every household is different. The tool shows a target split, not a check of what actually happened last month.
This is an illustration based on the numbers you entered, not personal advice or a recommendation. Check current rules and amounts at gov.il or on the Capital Market, Insurance and Savings Authority website.
Frequently asked questions
What is the 50/30/20 rule?
Half of your take-home income goes to needs, thirty percent to wants and twenty percent to saving and to paying down debt beyond the minimum. It is a starting point you adapt to your situation, not a law.
What counts as a need and what counts as a want?
Rent or mortgage, bills, basic food, insurance and transport to work are usually needs. Restaurants, going out, subscriptions and holidays are usually wants. The edge cases are your call, and it helps to decide them in advance.
What if my needs go over 50%?
You can choose another split, such as 60/20/20, and separately look for where fixed costs can come down. Even a small saving made regularly is a good start.
Should I use net or gross income?
Net income, after deductions. If your income varies, use the average of the last three months.
