Your net proceeds from selling a house = Sale Price – Outstanding Mortgage – Estate Agent Fees – Solicitor Fees – EPC – Mortgage Exit Fees – Early Repayment Charges. On a £300,000 sale with a £150,000 mortgage, you’d typically walk away with £140,000–£145,000.

Net Proceeds = Sale Price – Mortgage Balance – Agent Fees – Solicitor Fees – EPC – Mortgage Exit Fee – ERC – Other Costs

The question every seller really wants answered is: ‘How much will I actually walk away with?’ The sale price of your house is not what you’ll receive – estate agent fees, solicitor costs, mortgage repayment and various other charges are deducted before the remaining funds reach your bank account.

Our sale my house calculator works backwards from the sale price, deducting every cost to show you the exact net proceeds you can expect. This is the money you’ll have available for a deposit on your next property, or to put in the bank.

What This Means

Your net proceeds represent the money you’ll actually receive in your bank account after your solicitor has deducted all costs from the sale proceeds. This typically arrives on the day of completion, usually by late afternoon. If you’re buying another property simultaneously, the net proceeds are applied towards your new purchase, with any shortfall made up from your savings or new mortgage.

Net Proceeds Worked Example

Here’s a detailed example showing how net proceeds are calculated on a £300,000 sale with a £150,000 outstanding mortgage:

ItemAmountRunning Total
Sale Price£300,000£300,000
Less: Outstanding Mortgage–£150,000£150,000
Less: Estate Agent Fee (1.4% + VAT)–£5,040£144,960
Less: Solicitor Fees (inc. VAT & disbursements)–£1,100£143,860
Less: EPC Certificate–£80£143,780
Less: Mortgage Exit Fee–£150£143,630
Less: Early Repayment Charge (if applicable)–£0£143,630
Net Proceeds£143,630

In this example, the seller walks away with £143,630 from a £300,000 sale – approximately 47.9% of the sale price. The equity (sale price minus mortgage) is £150,000, but selling costs reduce this by £6,370 (4.2% of the equity).

Estimated Net Proceeds by Sale Price

Here are estimated net proceeds at different sale prices, assuming a 50% loan-to-value mortgage and a high street estate agent at 1.4% + VAT:

Sale PriceMortgage (50% LTV)Agent FeeSolicitor + OtherNet Proceeds% of Sale Price

Your actual net proceeds will differ based on your specific mortgage balance, choice of estate agent and any early repayment charges. Use our calculator above for a personalised estimate.

How to Maximise Your Net Proceeds

Every pound saved on selling costs is a pound more in your pocket. Here are the most impactful strategies:

  1. Reduce estate agent fees: Negotiate with high street agents (most will reduce from their asking rate), use an online agent (£699–£1,999 vs £3,000–£6,000+), or consider selling privately. This single decision can save £2,000–£5,000.
  2. Get competitive conveyancing quotes: Online conveyancers may charge 20–40% less than high street firms. Get at least 3 quotes and compare total costs including disbursements.
  3. Time your sale to avoid ERCs: If your fixed-rate mortgage ends within a few months, waiting could save 1–5% of your outstanding balance (£1,000–£10,000+).
  4. Maximise the sale price: Simple improvements like fresh paint, decluttering, professional photography and good staging can increase your sale price by 3–5% (£9,000–£15,000 on a £300,000 property) for a relatively small investment.
  5. Negotiate with your buyer: Don’t accept the first offer. Counter-offering and skillful negotiation by your agent can add thousands to the final sale price.

What Happens to Your Sale Proceeds

On completion day, your solicitor handles all financial transactions. Here’s how the money flows:

  • Step 1: The buyer’s solicitor transfers the full purchase price to your solicitor.
  • Step 2: Your solicitor redeems (pays off) your mortgage directly to the lender.
  • Step 3: Your solicitor pays the estate agent’s commission.
  • Step 4: Your solicitor deducts their own fees.
  • Step 5: If you’re buying the same day, the remaining funds are transferred to your purchase solicitor as part of the new purchase price.
  • Step 6: If you’re not buying immediately, the net proceeds are transferred to your bank account, typically arriving the same day (by late afternoon) or the following business day.

Your solicitor will prepare a detailed completion statement showing every deduction. Review this carefully before completion to ensure there are no surprises.

Understanding Your Equity Position

Your equity is the difference between your property’s value and your outstanding mortgage. It’s the starting point for calculating net proceeds:

Years of OwnershipTypical Equity (based on £300k purchase, 90% LTV)Equity Source
Purchase (Year 0)£30,000 (10% deposit)Deposit only
After 5 years£70,000–£100,000Mortgage repayments + house price growth
After 10 years£120,000–£180,000Mortgage repayments + house price growth
After 15 years£170,000–£260,000Mortgage repayments + house price growth
After 20 years£220,000–£350,000Mortgage repayments + house price growth

These estimates assume typical UK house price growth of 3–5% per annum and a standard repayment mortgage at typical interest rates. Your actual equity will depend on your specific mortgage type, interest rate, any overpayments made, and local house price movements.

To check your current mortgage balance, contact your lender or check your online mortgage account. To estimate your property’s current value, check comparable sales on the Land Registry, or use valuation tools on Zoopla or Rightmove.

Frequently Asked Questions

How much will I make from selling my house?
Your net proceeds from selling a house = Sale Price minus Outstanding Mortgage minus Estate Agent Fees minus Solicitor Fees minus Other Costs. On a typical £300,000 sale with a £150,000 mortgage, you’d receive approximately £140,000–£145,000 after all deductions. Use our calculator for a personalised estimate.
How do I calculate my equity in my house?
Equity = Current Property Value minus Outstanding Mortgage Balance. To find your property’s current value, check recent comparable sales on the Land Registry or get a free estate agent valuation. Your mortgage balance is available from your lender or online mortgage account. This equity, minus selling costs, is your net proceeds.
What percentage of the sale price do I lose to fees?
Selling fees (excluding mortgage repayment) typically total 2–3% of the sale price with a high street agent, or 1–2% with an online agent. On a £300,000 sale, that’s £6,000–£9,000 with a high street agent or £2,700–£4,000 with an online agent.
When do I receive the money from selling my house?
You receive the net proceeds on completion day. Your solicitor transfers the funds to your bank account after deducting the mortgage, agent fees and their own costs. The money typically arrives by late afternoon on the day of completion, though it can sometimes be the next business day.
Do I have to pay tax on the profit from selling my house?
If the property is your main residence and you’ve lived in it throughout ownership, you’re exempt from Capital Gains Tax under Private Residence Relief. If the property was rented out, used for business, or is a second home, CGT may apply at 18% (basic rate) or 24% (higher rate) on the gain above the annual exempt amount.
Can I sell my house for less than I owe on the mortgage?
This is called negative equity. You can technically sell, but you’ll need to find funds to repay the shortfall to your lender, or negotiate a ‘short sale’ where the lender agrees to accept less than the full balance. This is rare in the UK and affects your credit score. Speak to your lender and seek independent advice.
