When to use this calculator
- When you need a fast estimate before making a bigger decision.
- When you want to compare a few scenarios using the same assumptions.
- When you need a clearer starting point before using a detailed quote or formal document.
- When you want to sanity-check a figure you have seen elsewhere before you rely on it.
- When you are preparing for a conversation with an adviser, supplier, or lender and want to arrive with realistic numbers.
A realistic Ireland planning example
Use these sample inputs as a quick scenario test, then change one variable at a time to compare outcomes.
Loan Amount (€)
€280,000
Property Value (€)
€350,000
After entering these figures, review ltv and equity together rather than in isolation — each metric tells a different part of the story. Then rerun the tool with one input adjusted to see which variable has the biggest effect on all three outputs before you settle on a plan.
How to read your results
LTV
Loan-to-value helps you compare product eligibility and understand how much lender risk you are carrying at this deposit level. Crossing key LTV thresholds — typically 90%, 85%, or 75% — can unlock materially better interest rates.
Equity
Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.
Method & assumptionsAuthoritative sources
This calculator divides your outstanding mortgage or proposed loan amount by the property's current or purchase value, then expresses the result as a percentage. The figure it produces is your loan-to-value ratio. It assumes a straightforward first-charge residential mortgage and does not account for second charges, shared ownership arrangements, or Help to Buy equity loan balances, which can affect the effective LTV seen by a lender. The tool uses the figures you enter directly — it does not apply any valuation adjustment or index property prices. For remortgage purposes, you should use a current market valuation rather than your original purchase price. This calculator is for illustrative purposes and does not constitute mortgage advice.
Common mistakes
- !Using an assumption that is not supported by a current local quote, bill, statement or official source.
- !Treating a generic estimate as a lender, provider, payroll or tax authority decision.
- !Mixing monthly and annual inputs without converting them consistently.
- !Forgetting location-specific taxes, fees, eligibility rules or payroll deductions where they apply.
- !Testing only one scenario instead of checking how a cautious assumption changes the result.
What to do next
- Run a second scenario with a cautious assumption so you can see the downside clearly.
- Compare the result with the related calculators below before making a decision.
- Check current local rules, eligibility and provider terms before applying or committing money.
- Keep a record of the assumptions so you can update the estimate when a quote, bill or pay figure changes.
- Use the result to prepare better questions for a lender, provider, adviser or employer rather than treating it as a final answer.
