Ireland version
How it works
Separate a regulatory ceiling from lender affordability. Irish principal-residence LTI/LTV rules are sourced; Canadian affordability here uses explicitly entered lender limits rather than claiming a national income multiple.
This is the Ireland planning view, with monetary inputs and outputs in EUR. A currency label does not establish that a tax rate, construction price, coverage rule or legal limit has been verified locally. The inputs and limitations below describe the actual scope.

Formula
Cap = min(income × multiple, property value × LTV, positive entered lender cap).
Calculations retain numeric precision internally. Displayed values are rounded for readability. Quantities that must be purchased as whole units are rounded up only where the formula explicitly requires it.
Read the inputs before calculating
- Annual gross household income: Enter the quantity described by the label.
- Property price: Enter the quantity described by the label.

Reproducible worked example
The following is a fictional arithmetic example, not a local quote, a verified claimant or a market forecast. Its values are included so the formula can be checked. The form does not automatically confirm any verification checkbox.
| Input | Example value |
|---|---|
| Annual gross household income | 80,000 |
| Property price | 350,000 |
| Cash deposit | 70,000 |
| Irish borrower category | first |
| Other verified lender income multiple | 3.5 |
| Other verified lender maximum LTV | 80 |
| Separately underwritten affordability cap (zero means not assessed) | 0 |
| Output | Calculated result |
|---|---|
| Requested loan | EUR 280,000 |
| Modeled rule-based loan cap | EUR 315,000 |
| Deposit shortfall against modeled cap | EUR 0 |
Interpreting a changed assumption
Start with one complete scenario and change only one input when diagnosing a difference. Recheck units, the period of every rate, whether an amount is recurring or one-off, and whether a cost is already included elsewhere. A larger calculated benefit is not evidence that an assumption is more likely to occur.
Limitations
- Planning calculation, not a tax return, benefit decision, credit approval or legal opinion. No eligibility is inferred from a numeric result.
- Only the stated tax year and expressly supported rule components are included. Entered amounts require independent verification.
- Ireland: principal-residence first-time buyers 4× income, subsequent buyers 3.5×; LTV 90%. Buy-to-let LTV 70%, no regulatory LTI modelled. Lender exception allocations are not an individual entitlement.
- A numeric ceiling is not approval. Credit, expenses, insurance, valuation and underwriting remain separate.
Frequently asked questions
What does this Mortgage Capacity Planning result represent?
Separate a regulatory ceiling from lender affordability. Irish principal-residence LTI/LTV rules are sourced; Canadian affordability here uses explicitly entered lender limits rather than claiming a national income multiple. It applies the displayed formula to your inputs; it does not infer omitted facts.
Are the starting amounts verified Ireland prices or legal rules?
No. Numeric defaults are illustrative unless an input or dated reference explicitly identifies a researched component. Currency is EUR; local quotes, eligibility and unsupported rules must be entered and verified separately.
What must I check before relying on the result?
Planning calculation, not a tax return, benefit decision, credit approval or legal opinion. No eligibility is inferred from a numeric result. Only the stated tax year and expressly supported rule components are included. Entered amounts require independent verification.
Can I compare or share different assumptions?
Change one assumption at a time and use the browser-local project or share controls. A shared URL contains the encoded input values; do not include information you do not wish to disclose.
