How this mortgage affordability estimate is calculated
This calculator estimates borrowing power from gross income, deposit, buyer type, Central Bank LTI/LTV rules, and a standard repayment mortgage formula.
- Gross annual income is combined for single or joint applicants.
- The calculator applies the relevant Central Bank loan-to-income rule: 4× income for first-time buyers or 3.5× income for second/subsequent buyers. Buy-to-let uses LTV only in this version.
- The relevant loan-to-value limit is applied: 90% for principal home mortgages and 70% for buy-to-let properties.
- Deposit, income limit, and LTV are compared to estimate the maximum mortgage, property budget, minimum deposit, and monthly repayment.
Source note: Central Bank of Ireland mortgage measures. Lenders can apply stricter criteria and limited allowances may apply. This is an estimate only and not financial advice.

Central Bank Mortgage Rules in Ireland
Irish mortgage lending is guided by loan-to-income and loan-to-value limits. These rules are designed to reduce the risk of borrowers taking on unsustainable loans.
Loan-to-income (LTI) limits the mortgage amount compared with gross annual income. First-time buyers are generally capped at 4 times income, while second/subsequent buyers are generally capped at 3.5 times income.
Loan-to-value (LTV) controls the deposit needed. Principal home buyers generally need at least 10% deposit, while buy-to-let buyers generally need 30% deposit.
Lenders may apply stricter rules and may have limited flexibility allowances. This calculator uses the standard rules as a planning guide.
Deposit and LTV Explained
Your deposit can be just as important as income. Even if your income supports a certain mortgage amount, a low deposit can limit the property price you can target.
For a principal home at 90% LTV, a buyer normally needs at least 10% deposit. For example, a €300,000 property requires about €30,000 deposit before additional buying costs.
If your deposit is the limiting factor, saving more can increase your maximum property budget. If income is the limiting factor, adding deposit may help with the purchase price but may not increase the mortgage amount itself.

Mortgage Affordability vs Mortgage Repayment
A mortgage affordability calculator and a mortgage repayment calculator answer different questions.
Mortgage affordability asks: how much might I be able to borrow based on income, deposit, and lending rules?
Mortgage repayment asks: what would my monthly payment be on a specific mortgage amount, interest rate, and term?
Use this page first to estimate borrowing power. Then use the Mortgage Repayment Calculator to test monthly payments on the property price or mortgage amount you are considering.
