What is the 50/30/20 budget rule?

It is a commonly cited split where half of take-home pay covers needs like rent, bills, food and transport, about a third covers wants, and the last fifth goes to savings and debt. The arithmetic only holds while essentials fit inside half the income.

What if my rent is more than half my income?

Then the arithmetic of 50/30/20 no longer works, because it assumes essentials fit inside half your income. A 70/20/10 split fits essentials of 50 to 70 percent, and 80/20 fits up to about 80 percent. Above that, no common split fits and everything sits in a single budget. This calculator reports which of those splits your figures fall inside; it does not tell you what to do about it.

Which budget rule is best?

There is no single best rule, and this page does not pick one for you. Each split assumes a different share of income goes to essentials, so the arithmetic only works while your fixed costs fit inside that share. The calculator shows which splits your entered figures fall inside and what each one comes to in money.
