Stamp Duty & Closing Costs Calculator

This calculator works out the tax you pay when you buy a home. In the UK that is stamp duty: Stamp Duty Land Tax (SDLT) in England & Northern Ireland, Land and Buildings Transaction Tax (LBTT) in Scotland, and Land Transaction Tax (LTT) in Wales. In the United States there is no national purchase tax; instead buyers pay closing costs (typically 2–5% of the price) plus, in many states, a transfer tax.

This is an estimate for guidance only, not tax or financial advice. The tax you actually owe depends on your circumstances, the reliefs you qualify for, and local levies. Confirm with a solicitor, conveyancer, or the relevant tax authority before you budget.

How to Use

1. Region: choose England & NI, Scotland, Wales, or United States. The currency and the tax model change to match.
2. Property Price: enter the purchase price.
3. Buyer Type (UK only): pick First-time, Moving, or Additional (a second home or buy-to-let). This changes which rate table applies.
4. State (US only): pick a state to estimate its transfer tax, or Other / typical for a national-typical figure.
5. Read the result: the headline tax (UK) or typical closing costs (US) appears in the bottom bar. The Results tab shows the slice-by-slice band breakdown (UK) or component ranges (US).

How Slice (Banded) Taxation Works

UK stamp duty is a slice (or progressive) tax. This is the single most misunderstood thing about it. Each portion of the price that falls inside a band is taxed only at that band's rate, not the whole price at the top rate.

Worked example, England & NI standard rates, price £295,000:

Only the £45,000 above £250,000 is taxed at 5%, not the entire £295,000. The effective rate here is £4,750 ÷ £295,000 ≈ 1.61%, far below the 5% top-band rate. This is exactly the worked example published by gov.uk.

The Three UK Regimes Side by Side

Each UK nation runs its own tax with its own bands and effective dates. Current standard residential bands:

Rates effective from: England & NI, 1 April 2025, Scotland, 5 December 2024 (ADS change; standard bands unchanged since April 2021), Wales, 10 October 2022. The calculator shows the effective date for whichever regime you select.

First-Time Buyer Relief

First-time buyers can pay less, but the rules differ sharply by nation, and England has a hard cliff.

• England & NI: relief raises the nil-rate band to £300,000, with a reduced 5% band up to £500,000. But it applies only if the price is £500,000 or less. Buy for £500,001 and you lose the relief entirely: you pay standard rates on the whole price. A £600,000 first-time purchase therefore costs £20,000 (standard), not the £15,000 you might expect by extrapolating the relief table. This £500,000 cliff is intentional.
• Scotland: relief raises the nil-rate band from £145,000 to £175,000, with no upper price cap; it simply takes the first £175,000 tax-free on any purchase.
• Wales: there is no first-time-buyer relief at all. First-time buyers pay the standard LTT rates.

Additional Properties (Second Homes & Buy-to-Let)

Buying a property that isn't replacing your only or main home triggers a higher charge:

• England & NI: standard rates + 5 percentage points on the whole price.
• Scotland: the Additional Dwelling Supplement (ADS), 8% of the whole price, on top of standard LBTT.
• Wales: a separate, full higher-rate band table (not a flat surcharge); e.g. a £260,000 additional purchase is £15,950.

US Closing Costs

The US has no federal stamp duty. Instead, a buyer pays closing costs at settlement. The Consumer Financial Protection Bureau (CFPB) puts these at 2% to 5% of the purchase price (excluding the down payment). This calculator headlines the midpoint (3.5%) and shows the full range.

Typical components (illustrative; the CFPB enumerates these categories but does not publish fixed percentages):

• Lender / origination fees: the cost of arranging the mortgage.
• Title insurance & lender's title: protects against defects in the property's ownership history.
• Escrow / settlement & appraisal: the closing agent and valuation.
• Prepaids: property tax, homeowner's insurance, and prepaid interest held in escrow.

On top of these, many states levy a transfer (or recording / excise) tax. These vary enormously: Texas and Arizona have none at the state level; Florida charges 0.70%; Pennsylvania 1% (plus local add-ons). Sixteen states levy no state-level transfer tax. The calculator's state figure is the state rate only; county and city taxes frequently add on top, and who pays (buyer or seller) varies by state and negotiation.

Formula & How It's Calculated

For a progressive band table with bands defined by an upper bound u and rate r, and a purchase price P:

$$\text{tax}=\sum _k\left(\min (P,u_k)-u_{k-1}\right)\cdot r_k$$

summed over each band the price reaches (with u_0 = 0). The effective rate is:

$$\text{effective rate}=\frac{\text{tax}}{P}\times 100\%$$

For US closing costs, with low/high bounds l and h (0.02 and 0.05):

$$\text{typical}=P\times \frac{l+h}{2},\text{transfer tax}=P\times r_{\text{state}}$$

The calculator does this band arithmetic in 64-digit decimal precision so the penny totals are exact.

A Note on Budgets and Rate Changes

UK governments adjust stamp duty thresholds at Budgets and fiscal events, sometimes temporarily. The England & NI nil-rate band reverted to £125,000 and the first-time-buyer cap to £500,000 on 1 April 2025, for example. Always check the effective date shown on the calculator and confirm against the official source before committing, especially near a known change date.

Frequently Asked Questions

Is stamp duty paid on the whole price at one rate? No. It is a slice tax: each band's rate applies only to the portion of the price within that band.

Do first-time buyers always pay less? Not in Wales (no relief), and not in England above £500,000 (relief is lost entirely above the cap).

Who pays transfer tax in the US? It varies by state and is negotiable; in much of the US the seller customarily pays, but local custom differs.

Are local US taxes included? No. The calculator shows the state transfer-tax rate only. County and city taxes often add a significant amount on top.

Is this the exact amount I'll pay? Treat it as a close estimate. Reliefs, leasehold/freehold differences, mixed-use property, non-resident surcharges, and local levies can all change the figure.
