About Dev Finance Calcs
Working calculators and plain-English editorial for people actually running the numbers on UK property development schemes.
What this is
A small set of high-quality calculators covering the mechanics that matter when you're raising UK development finance, bridging, or exit facilities. No registration walls, no call-back-required forms, no "your number will appear on screen after you hand over your email". The numbers calculate in your browser.
Who writes this
Calculators and explainers by Alex Hargrave, development finance writer. Alex spent eight years underwriting UK residential development loans before moving into independent commentary. Writes pragmatic explainers aimed at first- and second-time developers.
Editorial independence
This site is not a broker or lender. We don't hand your details to anyone. If you want live indicative terms on an actual deal, the fastest route is a broker with a current lender panel — which is why we occasionally point readers at Construction Capital . They have no editorial input here.
Corrections
Notice something wrong? Rates move, lender appetite shifts, calculator defaults drift. Let us know and we'll fix it.
