What is the Downsizing vs Passing Home to Children Calculator?
The Downsizing vs Passing Home to Children Calculator helps UK homeowners compare whether it is financially better to downsize and gift equity to their children during life, or keep the family home and pass it on later through inheritance. It focuses on when money is most useful to children, typically in their mid-30s to early 40s, versus receiving it much later in life.
How the Calculator Works?
This calculator compares two clear strategies side by side.
In the Downsize and Gift Now scenario, you sell your current home, buy a smaller property and gift the released equity to your children today. The model assumes children may use part of the gift for a house deposit and invest the remainder. It applies UK inheritance tax rules, including the seven-year taper relief, and tracks how the investment grows until your death. The downsized home is also inherited later.
In the Keep Home and Inherit Later scenario, you remain in your current property for life. The home grows in value over time and is inherited by your children when you die. The calculator applies inheritance tax to the full value of the home and shows what your children receive net of tax, but only later in life.
All calculations are UK-specific and shown in real-world terms, allowing you to compare not just how much your children receive, but when they receive it.
Step One: Enter Your Property and Life Details
Add your current home value, expected house price growth, your age when making the decision and assumed life expectancy.
Step Two: Set Downsizing and Gifting Assumptions
Enter the value of the downsized property, transaction costs, number of children, their current ages, expected investment returns and how much of the gift is used for house deposits.
Step Three: Compare Outcomes for Your Children
Review how much your children receive under each strategy, both in total and per child. The results highlight the financial difference and the timing of when money becomes available.

What is the Downsizing vs Passing Home to Children Calculator??
It is a UK-specific planning tool that compares downsizing and gifting equity during life versus passing the family home on later, highlighting both financial outcomes and the timing of benefits for children.
What question does this calculator help answer?
It helps answer whether money is more valuable to your children now, when they are making major life decisions, or later in life when they inherit your home.
Does the calculator include UK inheritance tax rules?
Yes. It applies current UK inheritance tax allowances, rates and seven-year taper relief for lifetime gifts.
Why does timing matter so much?
Money received in a child’s mid-30s or early 40s can help with house deposits, career choices and family stability. The same money received decades later may have far less practical impact.
Does it account for investment growth on gifted money?
Yes. Any portion of the gift not used for a deposit is assumed to be invested and grown until your death, then passed on to your children.
Do children still inherit a property if I downsize?
Yes. In the downsizing scenario, children inherit the downsized property in addition to benefiting from the earlier gift.
How are results shown per child?
The calculator breaks down how much each child receives, including deposit support, invested growth and their share of the inherited property.
Is this calculator about reducing inheritance tax?
Partly, but the main focus is usefulness, not just tax efficiency. The tool highlights both tax effects and real-life outcomes.
Does the calculator include home maintenance and upkeep costs?
No. The calculator focuses on property values, gifting, investment growth and inheritance tax to keep the comparison clear. However, in reality, larger homes often come with significantly higher maintenance, repair and running costs over time. Roofs, heating systems, gardens and general upkeep can become more expensive and more burdensome as you get older.
For many people, downsizing reduces not just financial complexity but also stress, time and ongoing responsibility. While these costs aren’t explicitly modelled here, they can have a meaningful impact on both quality of life and long-term finances and are worth factoring into your decision.
How accurate are the projections?
They are based on the assumptions you enter. The calculator is best used to compare scenarios rather than predict exact outcomes.
