When to use this calculator
- Before comparing mortgage products, brokers or repayment types.
- When you want to test how a different deposit, rate or term changes the payment.
- When you need a quick estimate before using a formal illustration or agreement in principle.
- When you are stress-testing your budget against a higher rate.
A realistic Ireland planning example
Use these sample inputs as a quick scenario test, then change one variable at a time to compare outcomes.
| Input | Value |
|---|---|
| Annual Gross Income — Applicant 1 (€) | €45,000 |
| Annual Gross Income — Applicant 2 (€) | €45,000 |
| Buyer Type | First-time buyer (FTB) |
| Property Value (€) | €350,000 |
After entering these figures, review maximum mortgage, lti limit ({symbol}) and ltv limit ({symbol}) together rather than in isolation. Then rerun the tool with one input adjusted.
How to read your results
Maximum Mortgage
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
LTI Limit ({symbol})
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
LTV Limit ({symbol})
Loan-to-value is the mortgage as a percentage of the property value. Crossing common LTV bands can change product eligibility and pricing.
Est. Monthly Repayment
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
Mortgage LTV
Loan-to-value is the mortgage as a percentage of the property value. Crossing common LTV bands can change product eligibility and pricing.
Loan-to-Income
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
Method & assumptionsAuthoritative sources
This calculator applies the Central Bank of Ireland's mortgage rules updated in 2023. First-time buyers face a Loan-to-Income limit of 4.0 times gross income and a Loan-to-Value cap of 90%. Second and subsequent buyers are limited to 3.5x LTI and 80% LTV. The maximum mortgage displayed is the lower of the two limits — exactly how Irish lenders determine each borrower's ceiling. The estimated monthly repayment uses a standard capital-and-interest amortisation formula on the maximum loan at the rate and term you input.
This tool does not model lender allowances above the standard limits, Help to Buy contributions, First Home Scheme equity stakes, or cashback offers. Income should reflect basic gross salary; commission, bonuses, and rental income are assessed differently by each lender. LTI and LTV figures for your requested loan help you gauge your position before approaching a bank or broker.
Common mistakes
- !Mixing up loan amount and property value, which distorts affordability and LTV.
- !Using a headline rate but forgetting fees, insurance or repayment type.
- !Testing only one term length instead of comparing payment and total cost together.
- !Treating the result as a lender decision rather than a planning estimate.
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.
