How it works
What this calculadora actually does
Every Loan-to-Value (LTV) calculadora on this page runs the same loan to value calculadora logic a chartered accountant or coursework tutor would scribble on the back of an envelope — just faster, and reproducible.
Loan-to-Value (LTV) calculadora is built to give you a clean, explainable answer without the usual wall of ads — type the numbers, read the result, keep moving.
Small rate differences stack up over years — always run the maths before signing. Pull last month’s statement open on another tab — then run the sums and the rest of this page explains what the answer means.
Work out the LTV ratio on a UK mortgage from property value and deposit, with standard LTV bands and indicative rate impact.
On this page you will see Loan to value ratio, LTV and Deposit treated as first-class terms — each one is linked to the calculators and references that use it, so you can follow the thread without retyping queries into a search bar.
If it helps, jump straight to the Finance hub or compare with the Mortgage Repayment Calculator and the House Deposit calculadora — those two calcs are the ones readers usually open right after this page.

The quickest way to sanity-check any formula is to try it on figures you recognise. Try these:

Moments this tool earns its keep
Loan-to-Value (LTV) calculadora is aimed at people arriving with questions like these:
- "What is LTV"
- "LTV mortgage"
- "90 LTV"
- "What is loan to value"
- "How to calculate loan to value"
- "Loan to value formula"
Where the number stops being useful
Every tool has an edge where it stops being the right answer. Loan-to-Value (LTV) calculadora is no exception:
- For legally binding tax or medical decisions — cross-check with HMRC, NHS or a qualified professional.
- For very large or very small extremes the rounding error outgrows the useful precision.
- When the underlying rate or threshold has changed since the page was last reviewed — always verify with the primary source.
- When the input you have is already a derived figure (net of something) — feeding it in as "gross" will double-subtract.
Mistakes we see over and over
Every time you run the sums for a new scenario, one of these creeps in — it's worth knowing them ahead of time.
- Misreading the unit in the label — 'per year', 'per month' and 'per day' versions of the same figure differ by 12× or 365×.
- Taking a ratio and multiplying it by the wrong side of the inputs — always write the ratio as A/B with labels before running.
- Trusting a screenshot of someone else’s calculation — rerun it yourself with the same inputs, numbers drift.
- Assuming percentages add up. 10% off then 10% more is not the original price — it is 99% of it.
- Not refreshing the page when thresholds are date-sensitive. If the page was cached yesterday, bank rates may already be yesterday’s.
The sources behind the numbers
Where the maths needs an external authority, we cross-check against:
- Bank of England
- FCA
- MoneyHelper
