Mortgage Calculator by Country
Residential mortgage payment, total interest, and transaction costs — with country-specific LTV limits, stamp-duty / transfer-tax rules, and three rate structures: fixed for the whole term, fixed period then revert (UK standard), or variable with built-in stress test.
- Fix-then-revert is the default UK structure: 2-yr or 5-yr fixed initial period, then the loan reverts to the lender's Standard Variable Rate (SVR) for the rest of the term. Use the 'Fix + revert' option above and expect a payment shock at the end of the fix.
- Buy-to-let max LTV typically 75% (some lenders 80%). Non-resident BTL often capped at 70%.
- Stamp Duty Land Tax (SDLT) is progressive. Additional residential property carries a 5% surcharge across all bands.
- Lenders apply rental stress tests (typically 125–145% of mortgage interest at SVR + 1pt). Use the 'Variable' option above to model the stressed rate.
- Max term 35–40 years on residential, 25–30 on BTL. Max borrower age at maturity usually 75.
- Solicitor + survey + lender fees average ~1.5% of price for a buy-to-let purchase.

Is this an investment property?
A mortgage calculator tells you the payment. AssetCentral tells you whether the property actually makes money — yield, cash flow and a plain-English verdict.
How to interpret your results
- Monthly payment is the headline number. Compare it to your rental income (for a buy-to-let) or your monthly budget (for a primary residence). If it eats more than 35% of net income, banks in most of Europe won't approve.
- Fix-then-revert (UK default): the loan amortises over the full term, but at the end of the fix period the lender re-amortises the remaining principal at the reversion rate. A payment jump of more than 25% is flagged — plan to remortgage 3–6 months before the fix ends.
- Variable + stress test: lenders in most regulated markets approve loans against a stressed rate, not the headline rate. The stress add (default +2 pts) shows what your monthly payment would be if rates moved against you.
- Effective LTV must stay within the country's typical maximum, especially for non-residents. If the calculator warns you, expect either a larger deposit requirement or a specialist (more expensive) lender.
- Cash needed at completion is the total upfront cost — deposit + transfer tax / stamp duty + notary / legal / agent fees. In most European countries, transaction costs add 7–15% on top of the deposit.
What this doesn’t include
Lender-specific stress test thresholds, early-redemption charges, mortgage life insurance, currency-conversion costs, recurring property taxes (council tax, ENFIA, IBI, IMI, taxe foncière, etc.), and first-time-buyer schemes. The reversion-rate calculation uses a flat rate for years 3+; in practice you would typically remortgage before then to avoid the SVR. Country rules are simplifications — confirm with a local broker or notary before committing.
