LTV is the single most-quoted ratio in mortgage lending. Below 60% unlocks the cheapest rates. 75-80% is the common middle tier. Above 90% is expensive and often requires insurance. A 240,000 balance on a 300,000 property is 80% LTV — typical first-time buyer territory.
Quick example
With mortgage balance of 240,000 and property value of 300,000, the result is 80.00%. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Mortgage Balance and Property Value. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.
What's happening under the hood
Standard LTV definition: outstanding loan divided by current property value. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
Why this matters before you sign
A mortgage is usually the biggest single financial commitment a person makes. The difference between a well-chosen product and a hasty one can run into tens of thousands over the life of the loan. Running the numbers here before committing is the cheapest form of due diligence available.
What this doesn't capture
The figure excludes arrangement fees, valuation costs, legal fees, insurance, and any early-repayment charges — those can add several thousand to the headline cost. Rate changes at renewal for fixed-term deals will shift the picture further. Use this for the core interest/principal math and add the other costs on top.
Where to go next
This calculation rarely sits alone in a planning exercise. If you're running these numbers, you'll probably also want the mortgage calculator, the home equity calculator, and the combined ltv calculator — each one answers a different question in the same territory. Treating them as a set rather than in isolation usually produces a more honest picture.
LTV produces a percentage based on the inputs provided.
