The 30 Percent Rule: The Line Between Healthy and Trapping Debt

How to calculate it

Add up every monthly debt payment: mortgage, car, credit cards, buy-now-pay-later, personal loans, and money owed to family. Divide by monthly net income and multiply by a hundred. That is your ratio.

Why 30 percent

It is not a magic number. It emerged because below it, most households still have enough room to absorb an unexpected cost without borrowing again. Above 40 percent, one car repair or one medical bill is enough to force a new loan, and that is where the cycle starts.

The usual miscalculations

Three mistakes dominate: using gross instead of net income, ignoring paylater because "the amounts are small", and leaving out family loans because they carry no interest. All three make the ratio look healthier than it is.

If your number is already past the line

The order matters: stop new borrowing, list every debt with its interest rate, pay the minimum on all of them, then send every spare unit of currency to the single highest-rate loan. Above 45 percent, add one more step - formally request restructuring. It is a routine procedure, and lenders prefer small steady payments to none at all.

Why cutting spending alone rarely closes the gap

At a high ratio, frugality can recover a modest amount while the problem is several times larger. Raising income almost always moves more - and lasts longer - than trimming an already thin budget.
