Life Annuity (Viager) Calculator
Calculate the down payment (bouquet) and monthly annuity for a viager real estate purchase based on seller age and property value.
What is a viager sale?
A viager is a uniquely French real estate transaction where the buyer pays a down payment (bouquet) plus a monthly annuity (rente) to the seller for life. In an occupied viager (viager occupe), the seller continues living in the property, which reduces the purchase price by the value of the occupancy right (DUH).
Down Payment (Bouquet)
A lump sum paid at signing, typically 20-30% of the property's occupied value. This amount is freely negotiated between buyer and seller.
Monthly Annuity (Rente)
A monthly payment made to the seller for life, calculated based on the remaining value after the bouquet, divided by life expectancy.
Occupancy Discount (DUH)
When the seller continues to live in the property, a discount is applied based on age and life expectancy, typically reducing the price by 40-60%.
How the annuity is calculated
The annuity is based on the property value minus the occupancy discount (DUH) and the down payment. This remaining amount is converted into a life annuity using INSEE mortality tables and an expected return rate. The older the seller, the higher the monthly annuity (shorter expected payment period).
Risks and considerations
The viager is inherently uncertain: if the seller lives longer than expected, the buyer pays more than the property's value. Conversely, early death benefits the buyer. The famous case of Jeanne Calment, who outlived her buyer, illustrates this risk perfectly.
