Why use our downsizing calculator?
Downsizing involves more than just selling one home and buying another. Estate agent fees, property taxes, legal costs, and moving expenses can all affect the final outcome. This calculator brings those details together and gives you an estimate of the overall financial impact, so you can see more than just the difference in house prices.
It shows you the costs of selling, including estate agent fees and mortgage exit charges, alongside the full buying costs for your new property. Regional property taxes are applied automatically, and the results also reflect whether you are buying an additional property. By combining all of these elements, the calculator estimates your net cash from the move and highlights the overall financial effect of downsizing.
The results update instantly as you adjust the figures, so you can test different home values, fees, and purchase costs before making decisions. This makes it easier to explore “what if” scenarios and understand how various factors may change the outcome.
The benefit is transparency. Instead of working through separate costs in isolation, the calculator provides a single view of selling, buying, and moving expenses, helping you see the estimated net position of your downsizing move in one place.

What is Downsizing, and how does it work?
Downsizing refers to selling your current home and purchasing a smaller, less expensive property.
This is typically done to access capital from your current home, reduce ongoing housing costs, or simplify your living situation, especially as life circumstances change, such as when children leave home or you approach retirement.
This arrangement enables you to tailor your living space to suit your current needs better, potentially freeing up capital while remaining a homeowner.
How it works
Downsizing involves several key features:
Eligibility and money released
Anyone who owns a home can choose to downsize. The amount of money you can release depends on the difference between the sale price of your current home (minus selling costs and any outstanding mortgage) and the purchase price of your new, smaller home (plus buying costs).
The amount of money you release is influenced by the value of your current home, the price of the new home, and the associated costs of both selling and buying.
Selling your current home
To downsize, you first sell your existing property on the open market. This involves typical selling processes, including valuing your home, engaging an estate agent, and incurring associated fees such as estate agent commissions and legal costs. You will also need to repay any outstanding mortgage on the property from the sale proceeds.
Buying a new, smaller home
Simultaneously or shortly after selling, you purchase a new, smaller property that has fewer rooms or is in a less expensive location. This new home will typically have a lower purchase price, allowing you to benefit from the equity released from your larger property.
Ongoing costs and financial impact
A key motivation for downsizing is often to reduce ongoing housing expenses. A smaller, less expensive home typically means lower monthly mortgage payments (or no mortgage at all if enough equity is released), reduced council tax, and lower utility and maintenance costs.
Released capital and financial planning
The capital released from downsizing can be used for various purposes, such as boosting retirement funds, paying off existing debts, helping family members, or covering other living expenses. This process can significantly improve your financial flexibility.
When the process ends
The downsizing process concludes once your original property is sold, and you have successfully purchased and moved into your new home. Any remaining capital after all selling and buying costs are covered and new mortgages are arranged becomes available to you.
Examples of how downsizing could work
Here are two examples to illustrate how downsizing might function in different situations:
Sarah downsizes to raise funds
Sarah, aged 68, owns a house valued at £450,000 with £50,000 remaining on her mortgage. Her children have moved out, and she wants to reduce her living expenses and free up funds for retirement. She decides to sell her current home and buy a smaller flat for £250,000.
Sarah’s downsizing scenario
Sarah sells her current home for £450,000. After typical selling costs, including a 1.5% estate agent fee (£6,750), legal fees (£1,500), and repaying her £50,000 mortgage, she has £391,750 in net cash from the sale. She then purchases her new flat for £250,000.
This involves various buying costs such as Stamp Duty of £2,500 (based on current England rates), legal fees (£2,000), a survey (£500), and moving costs (£1,000), totalling £6,000. The overall cash she needs for this purchase is £256,000.
After both transactions are complete, Sarah successfully releases £135,750 in tax-free capital (£391,750 net cash from sale minus £256,000 cash needed for purchase).
This significantly boosts her retirement funds, and her new flat also comes with lower ongoing expenses, such as council tax and utility bills.
David and Maria downsize to reduce outgoings
David and Maria, both 62, own a house worth £300,000 with a £100,000 interest-only mortgage. They are looking to eliminate their mortgage payments and significantly reduce their monthly outgoings before fully retiring.
They decide to sell their current home and purchase a smaller bungalow for £200,000, aiming to buy it mortgage-free.
David and Maria’s downsizing scenario
They sell their home for £300,000. After accounting for selling costs like a 1.5% estate agent fee (£4,500), legal fees (£1,200), and repaying their £100,000 mortgage, they are left with £194,300 in net cash from the sale.
Their new bungalow costs £200,000. The buying costs include Stamp Duty of £1,500, legal fees (£1,800), a survey (£400), and moving costs (£800), adding up to £4,500. This means the total cash needed to purchase the new home is £204,500.
While the net cash from their sale (£194,300) doesn’t quite cover the full cash needed for the new purchase (£204,500), they use £10,200 from existing savings to cover the shortfall.
This allows them to buy the new home outright, eliminating their £100,000 mortgage and achieving their goal of a retirement free from mortgage payments and with significantly reduced monthly bills.
Important considerations
Downsizing is a significant financial and lifestyle decision with several implications.
Understanding the following points is very important:
Reduced space. Moving to a smaller home naturally means less physical space. This may require decluttering and parting with possessions, which can be an emotionally challenging process.
Moving costs. While the goal is to release capital, there are upfront costs involved in moving, including legal fees, property taxes (like Stamp Duty Land Tax), surveyor fees, and removal expenses. These costs need to be factored into your budget.
Impact on social life/community. Moving to a new area might mean leaving an established community, which can impact social connections and access to familiar amenities.
Property market fluctuations. The amount of equity you release can be affected by the property market. If the market is slow, selling your current home might take longer or achieve a lower price than expected.
Professional advice is essential. It is highly advisable to seek independent financial advice to understand the full financial implications of downsizing, including how it might affect your savings, investments, and any benefits you receive. Legal advice is also crucial to navigate the conveyancing process for both the sale and purchase.
