The repayment period of the zero rate loan and the amount of the monthly payments are calculated through three metrics. A family coefficient will influence the amount of income taken into account to determine a slice. The detection of this tranche will give the terms of repayment.

## Family coefficient of the zero-interest loan

The family coefficient will be used on the amount of “resources” taken into account.

As a reminder, there are two ways to estimate this amount:

- The accumulation of reference tax revenues for year N-2 of the borrower (s) and the persons who will occupy the dwelling. For example, if the acquisition is made in 2014, the reference tax revenues to be taken into account will be those of the 2012 tax notice.

Or

- The total cost of the transaction divided by 10 (“floor income”)

The highest amount of the two calculations is the one selected. We must apply the family coefficient that divides this number. We obtain a result that will make it possible to find the slice in which the borrower is located.

## The zero rate loan tranches

After dividing the income by the family coefficient, it is necessary to refer to the following table to find the slice in which the borrower is located.

The borrower can finally calculate the monthly payments of his zero rate loan by referring the tranche obtained in the table of conditions of repayment of the loan at zero rate.

## Zero rate loan refund conditions

Depending on the unit, the household will reimburse their PTZ over a period of between 12 and 25 years. It may also benefit from a total deferral of depreciation if it belongs to one of the first three installments, which means that the household will not start repaying their loan until after this deferral period.

Example:

- With deferred amortization: A single borrower can claim a zero-rate loan over € 39,000 in Zone A, the highest income calculation method is that based on his N-2 tax bill to 21,300 €. The family coefficient for a single person is 1. It therefore divides 21 300 € / 1 = 21 300 €. By consulting the table determining the tranches this borrower falls in the second tranche (less than 22 000 €). The terms of repayment of his loan will begin with a period with a total grace period of the loan of 7 years, then a period of 18 years of repayments.

The monthly payments of his + 39,000 ptz will be as follows: 0 € for 84 months (= 7 years), then he will pay for 216 months (18 years) a monthly payment of 180,56 € (= 39,000 € / 216 months ). - Without the grace period: A two-person household can claim a zero-interest loan of more than € 39,000 in zone B1, the highest income calculation method is that based on the total cost of the split operation by 10. The amount withheld is 33 450 €. The family coefficient for two individuals is 1.4. He therefore divides € 33,450 / 1.4 = € 23,893. By consulting the chart determining the tranches this borrower falls in the fifth tranche (less than 26 000 €). The repayment terms will be for 12 years without grace period.

The monthly payments of their zero rate loan 39 000 € will therefore be as follows: 270,83 € for 144 months or 12 years (= 39,000 € / 144)
