Work out the real numbers before you commit

Rates verified 15 Oct 2026

Six calculators, all on one page. Change any number and the answer updates as you type. Nothing is sent anywhere and nothing is saved β€” the figures stay in your browser unless you choose to message them to me.

Want me to sanity-check these numbers against a real project? Send me what you worked out and I'll tell you what I'd expect in practice.

How to read these: every result here is an estimate built from the numbers you typed. None of it is a quotation, a valuation, a tax computation or an offer of financing, and nothing here means a bank will approve a loan or that a property will rent or appreciate. Rates set by law are sourced and dated above; everything else is an assumption you can change. Disbursements, insurance, renovation, furnishing and agency fees are not included unless a calculator says otherwise. Check anything you plan to act on with your banker, your lawyer and your tax adviser.
