PropertyCalculators.ai exists because we got tired of watching good investors make bad decisions.
After years in development finance, we'd seen it too many times. Experienced property professionals losing money not because they lacked skill, but because they forgot to model CIL payments, miscalculated rolled-up interest, or used optimistic assumptions without realising it. One spreadsheet error can turn a £300,000 profit into a £90,000 loss. We've seen it happen.
So we built something better.
PropertyCalculators.ai is the UK's most comprehensive suite of property investment calculators. Over 70 specialist tools covering development finance, buy-to-let, HMO, leasehold, bridging, commercial property, serviced accommodation, and value-add strategies. Built by property finance professionals who understand how deals actually work.
Every calculator forces you to confront the assumptions that matter. No hidden formulas. No optimistic defaults. Just clear inputs, accurate outputs, and the confidence to make informed decisions.
Whether you're a developer appraising your next site, a landlord expanding your portfolio, or an investor evaluating your first acquisition, we give you the analytical tools to get it right.
The Property Calculator Podcast takes this further. Each episode breaks down one calculator in detail – what it does, when you need it, and the mistakes we see investors make. Practical knowledge you can apply to your next deal.
Stop guessing. Start calculating.
