Property Calculators

In this first episode, we're not talking calculators yet. We're talking about why this platform exists in the first place.
It started with a development deal that looked solid on paper. Twelve flats, good location, experienced developer. But hidden inside a spreadsheet they'd used for fifteen years were errors that turned a projected £320,000 profit into a £90,000 loss. They'd never spotted them. Nobody had.

That moment crystallised something we'd seen repeatedly in development finance: smart, experienced property professionals making expensive mistakes not because they couldn't do the maths, but because they forgot to include something, used the wrong formula, or made optimistic assumptions without realising it.

This episode explains the thinking behind PropertyCalculators.ai. Why we believe better analysis leads to better decisions. Why we built tools that force you to confront the questions you might otherwise skip. Why we've created over 70 specialist calculators covering development finance, buy-to-let, HMOs, leasehold, bridging, and more – all built specifically for how UK property investment actually works.
Whether you're a seasoned developer or analysing your first buy-to-let, this episode sets the foundation for everything that follows.
The best deal you ever do might be the one you walked away from because the numbers didn't work.

What is Property Calculators?

The Property Calculator Podcast is your weekly deep-dive into the numbers that make or break property deals.
Every successful property investor, developer, and landlord knows that gut instinct isn't enough. The difference between a profitable acquisition and an expensive mistake often comes down to running the right calculations before you commit.
Each episode, we take one property calculator and break it down completely. Not just how to use it, but why it matters, when you need it, and the real-world scenarios where getting this number wrong costs investors thousands.
Whether you're analysing your first buy-to-let, structuring development finance for a ground-up project, or navigating the complexities of leasehold ownership, this podcast gives you the mathematical confidence to move forward – or the clarity to walk away.
What we cover:
Development finance essentials – GDV, build costs, residual land value, profit on cost, CIL, and mezzanine structures.
Buy-to-let fundamentals – yield analysis, stress testing, Section 24 tax impacts, and the BRRR strategy.
HMO deep-dives – viability calculations, fire safety costs, licensing fees, and Article 4 implications.
Leasehold mechanics – lease extensions, marriage value, ground rent capitalisation, and service charges.
Bridging and specialty finance – auction bridges, refurbishment funding, retained vs rolled interest.
Commercial property – yields, ERV, and capitalisation rates.
Serviced accommodation – occupancy break-evens, profit modelling, and holiday let taxation.
Value-add strategies – title splitting, planning gain, airspace development, and refurbishment returns.
Hosted by property finance professionals who've seen what happens when investors skip the maths, The Property Calculator Podcast turns complex calculations into practical knowledge you can apply to your next deal.
