Our tools provide a complete set of property KPIs. In the Transformation Calculator, among others: ROI, ROE, profit, profit margin, break-even price, LTV (initial and, where applicable, at exit), cash required, sale price and costs per sq ft, cost of delay, total costs and revenue, IRR, and payback period. In the Buy-to-Let Calculator, among others: gross yield, net yield, NOI, cap rate, DSCR, ICR, monthly and annual cash flow, cash-on-cash return, break-even occupancy, value per sq ft, effective rent per year, project IRR, equity IRR, and equity multiple.

Yes. For every KPI you can view the underlying formula and assumptions. This way you always know exactly how results are generated and can easily verify or adjust them.

Absolutely. You can enter all key parameters yourself, such as purchase price, refurbishment costs, financing terms and running costs. The tool updates the calculations instantly based on your input.

Yes. You can easily create, save, and reopen multiple projects. This helps you keep an overview of different investments or development plans.

Yes. With Before & After you can put a transformation project side by side before and after the refurbishment and instantly see the difference in costs, value and return. You open it from a saved transformation project under 'My projects'. The scenario comparison is being expanded further.

Yes. The Buy-to-Let Calculator calculates both monthly and annual cash flow, including interest, capital repayment and rent indexation. This gives you a realistic multi year return overview.

Yes. The tools are flexible and suitable for both. You can use them for flats, houses, offices, retail or mixed-use schemes.

Yes. For England and Northern Ireland the tool runs SDLT through its bands and stacks the surcharges that apply: +5% on an additional property and +2% for a non-UK resident. Scotland and Wales are covered too, each on its own levy: LBTT with the 8% ADS surcharge in Scotland, LTT on its own higher-rates table in Wales. Pick 'non-residential' as the buyer type and it switches to the non-residential bands. Markets that use a flat rate or your own thresholds are supported too: enter the bands and the tool works out the amounts.

Yes. The Transformation Calculator focuses on buying and refurbishing with a sale as the end goal, while the Buy-to-Let Calculator focuses on letting and long-term operation. Together they cover the full property lifecycle.

Yes. The tool supports twelve markets: the United Kingdom in three parts (England & NI with SDLT, Scotland with LBTT, Wales with LTT), the Netherlands, the United States, Spain, Dubai, Switzerland, Australia (New South Wales), Aruba, Curaçao and Bonaire (Caribbean Netherlands). For each country BRIX Calc applies the correct transfer tax and acquisition costs, in the matching currency, and the field labels and address fields adapt to the country you pick. For Switzerland and Spain it additionally shows the property gains tax on sale as a separate layer.

Yes, and that difference can be large. In Spain your tax flips from ITP (resale) to 10% VAT + AJD (new-build). In Dubai you pay no agent commission on off-plan (the developer covers it), while the DLD fee is 4% either way. BRIX Calc adjusts the right line items automatically once you pick the type.

For England & Northern Ireland, yes: if you buy as a non-UK resident, the tool automatically stacks the +2% non-resident surcharge across your whole purchase price, on top of the SDLT bands and any +5% for an additional property. Scotland and Wales do not have a non-resident surcharge, so the tool neither asks for it nor applies it there. The same now applies to Australia: tick “foreign person” and the tool adds the NSW +9% purchaser duty surcharge, plus the +5% annual land tax surcharge on the land value.

The core KPIs (return, IRR and cash flow) are before income tax and corporation tax, so deals and countries stay cleanly comparable. For Switzerland (Grundstückgewinnsteuer) and Spain (plusvalía municipal), BRIX Calc additionally shows a separate layer: your net profit after the property gains tax on sale. You set that rate yourself, so you can work with your own cantonal or municipal figures.

In the currency of the market: pound for the UK, euro for the Netherlands and Spain, dollar for the US, dirham for Dubai, Swiss franc for Switzerland and Australian dollar for Australia. As soon as you pick a country, the amounts, rates and labels switch with it, so you never confuse a pound with a euro.

Yes. All data is securely stored and accessible only to you. We use encryption and comply with GDPR regulations.

Yes. You export any calculation with one click as a polished PDF, with your key figures, charts and assumptions, so you can share your plans professionally with an investor, a broker or your lender. This works in both the Transformation and the Buy-to-Let Calculator. Sharing via a direct link is still on the roadmap.

Yes. The tools support financing with multiple parts, such as a development facility, a BTL mortgage and a personal loan. Each part can have its own interest rate, LTV, payment frequency, repayment schedule, fixed-rate period, interest type and term.
