If you’re buying a home in Ireland, you’ve probably noticed that mortgage repayment calculators pop up everywhere—from your bank’s website to independent brokers. They’re not all the same, though. Some pull live rates; others give ballpark figures that can miss by a couple hundred euro a month. Getting a handle on the right tool—and what inputs actually matter—can save you from unpleasant surprises once you draw down.

Free house repayment calculator

Several Irish websites let you calculate mortgage repayments without creating an account or handing over personal details. The best ones pull in real lender data rather than generic averages.

Top free tools

Mortgages.ie compares rates across Ireland’s leading lenders, advertising long-term fixed rates of 3.4% for up to 30 years, guaranteeing repayments for the full term (Mortgages.ie payments calculator). The Competition and Consumer Protection Commission mortgage calculator estimates repayments based on amount, term, and rate, though the consumer protection body notes results may vary by lender calculation method (CCPC.ie calculator). MoneySherpa.ie takes a different angle—it compares over 250 rates from all Irish lenders, updated daily, and calculates monthly repayments based on borrow amount, term, and rate (MoneySherpa.ie calculator).

How to use them

Enter your loan amount, preferred term, and either a known interest rate or the tool’s current estimate. Most calculators show a monthly repayment figure within seconds. Switcher.ie mortgage repayment calculator estimates payments for first-time buyers, movers, or switchers by searching a database of Irish lender rates (Switcher.ie calculators). Budget for stamp duty, legal fees, and insurance beyond repayments—these aren’t included in standard calculator outputs.

Editor’s note

Free calculators give indicative figures only. The Competition and Consumer Protection Commission recommends checking with your provider for exact repayments before applying for a mortgage (CCPC.ie calculator).

The implication: free tools work best as a starting point to gauge affordability and compare scenarios—don’t treat the output as a loan offer.

Repayments on 200k mortgage Ireland

A €200,000 mortgage in Ireland can mean very different monthly costs depending on your term and whether you lock into a fixed or variable rate.

Factors affecting repayments

Mortgage repayments depend on borrow amount, term, interest rate, fees, lender, fixed or variable type, and credit history (Switcher.ie calculators). A 1% interest rate rise increases a €300,000 mortgage payment by €187 per month according to Moneycoach.ie calculations (Moneycoach.ie repayment calculator). That translates to roughly €125 extra per month on a €200,000 loan over 30 years—money that could otherwise go toward overpayments or savings.

Example calculations

For context, Moneycoach.ie shows an example: €300,000 over 360 months at 4.9% fixed for 7 years then 3.95% costs €1,592 per month initially, with total repayable at €534,909 and APRC of 4.5% (Moneycoach.ie repayment calculator). Scaling down to €200,000 at similar terms would give you a lower but proportionate figure. Doddl.ie shows Ireland’s best variable rate at 3.47% as of April 22 (Doddl.ie repayments calculator), which would reduce monthly costs compared to the Moneycoach example’s fixed rate.

The catch

Variable rates can drop—but they can also rise. If you’re risk-averse, a fixed rate calculator might serve you better, even if the upfront rate looks slightly higher.

What this means: plugging your specific rate into a calculator matters far more than the loan amount alone. Even a 0.3% difference compounds into thousands over 20 or 30 years.

Bottom line: Using a calculator with your actual rate—even an estimate from a site like Doddl.ie—gives you a realistic picture. A 0.3% difference compounds into thousands over decades.

Early mortgage repayment calculator Ireland

Paying your mortgage off ahead of schedule sounds appealing, but early repayment often comes with penalties—and the maths aren’t always obvious.

Penalties and savings

Most Irish lenders charge early repayment charges (ERCs) if you pay above a certain threshold—typically 10% of your outstanding balance per year. Mortgages.ie offers a capital repayment and interest split calculator that shows monthly repayments, opening and closing balances, annual interest, and capital repayment breakdown (Mortgages.ie tax relief calculator). This lets you model what happens if you throw an extra €200 or €500 at your mortgage each month.

Calculator steps

To estimate early payoff costs, enter your current balance, interest rate, remaining term, and your proposed overpayment amount. The calculator will show revised totals and how many months—or years—you could shave off. Switcher.ie includes a stamp duty calculator alongside its repayment tool, useful if you’re planning to move rather than just overpay.

Bottom line: Using an early repayment calculator reveals the trade-off between short-term liquidity and long-term interest savings. For those with a fixed-rate term remaining, checking your ERC details before overpaying significantly is essential.

Loan repayment calculator Ireland

The same principles that govern mortgage calculations apply to other loan types, though the stakes—and often the numbers—are smaller.

For mortgages and loans

While the article focuses on mortgages, loan repayment calculators work for car finance, personal loans, and credit builder products. The key variables remain the same: principal amount, annual interest rate (APR), and repayment term. EBS.ie mortgage repayment calculator supports terms from 5 to 35 years (EBS mortgage repayment calculator), giving a sense of the range Irish lenders typically allow for home loans specifically.

Key variables

AIB.ie mortgage calculator determines borrowing capacity and monthly repayments based on income and expenses in under one minute (AIB mortgage calculator). Bank of Ireland’s mortgage calculator similarly estimates borrowing amount and monthly repayments (Bank of Ireland mortgage calculator). Local Authority Home Loan calculator estimates borrowing based on earnings but excludes Mortgage Protection Insurance (Local Authority Home Loan calculator), which is a common oversight for first-time buyers budgeting their full monthly outgoings.

The upshot

Moneycoach.ie calculators are for guidance, not loan offers—something worth remembering when you’re comparing outputs across different tools.

The pattern: broader financial health calculators (income versus expenses) tend to give more conservative figures than pure repayment calculators, which often assume you have the full loan approved at the stated rate.

AIB mortgage calculator

AIB runs one of the most widely used mortgage calculators in Ireland, partly because it taps into the bank’s full borrowing assessment process.

Features

The AIB calculator provides an Approval in Principle figure (AIB mortgage calculator), meaning you get a sense of what the bank might lend you before you submit a full application. It asks for income and expenses rather than just a target loan amount—giving you a more realistic picture of affordability. Permanent TSB offers a first-time buyer calculator that assumes a 3-year fixed high-value rate of 3.70% (APRC 4.52%) for €100,000 over 20 years (Permanent TSB first-time buyer calculator), and PTSB offers 2% cashback on monthly repayments until 31 December 2030—a tangible benefit worth factoring into your comparison.

How to access

Both AIB and PTSB calculators are available on their respective websites without logging in. The Competition and Consumer Protection Commission also provides a mortgage comparison tool for first-time buyers, switchers, and home movers (CCPC mortgage comparisons), which can help you cross-check what AIB offers against competitors.

Bottom line: AIB’s calculator leans on income-based affordability, making it useful for buyers uncertain about their borrowing ceiling. Permanent TSB adds a cashback sweetener that can meaningfully reduce effective borrowing cost if you qualify.

How to use a house repayment calculator

Follow these steps to get the most out of any mortgage repayment calculator in Ireland:

  1. Gather your numbers. Know your loan amount (or the amount you’re considering borrowing), your preferred term in years, and either a specific rate you’ve been quoted or the current best rate from a tool like Doddl.ie (currently 3.47% variable).
  2. Pick the right calculator. For first-time buyers comparing across lenders, use Mortgages.ie or CCPC.ie. For a quick borrowing estimate based on income, try AIB. For rate comparisons across 250+ products, MoneySherpa.ie updates daily.
  3. Enter your inputs. Start with your target loan amount and a standard term (20 or 30 years are common). Most calculators will immediately display a monthly repayment figure.
  4. Adjust the scenario. Tweak one variable at a time—extend the term to see if it reduces payments enough to make the property affordable, or enter a higher rate to stress-test your budget.
  5. Note the disclaimers. All calculators output indicative figures. The Competition and Consumer Protection Commission recommends confirming exact repayments with your chosen lender before applying (CCPC.ie calculator).
  6. Factor in extra costs. Stamp duty, legal fees, valuation, and insurance add thousands to your upfront bill—Switcher.ie includes a stamp duty calculator alongside its repayment tool.

For Irish first-time buyers, the choice of calculator shapes what comes next: a more accurate budget, a sharper comparison of fixed versus variable, and fewer surprises at drawdown. Running the same scenario across two or three tools—say, AIB for income-based borrowing and Doddl.ie for current best rates—gives you a realistic range rather than a false sense of precision.

Frequently asked questions

How accurate is a house repayment calculator?

Most mortgage repayment calculators are accurate to within a few euro if you use a current, lender-specific rate. The Competition and Consumer Protection Commission notes that results may vary by lender calculation method, so cross-check with your bank before committing (CCPC.ie calculator).

What interest rates to use for Ireland mortgages?

Use a rate you’ve been quoted by a lender, or a current market rate. Doddl.ie shows Ireland’s best variable rate at 3.47% as of April 22 (Doddl.ie repayments calculator), while Mortgages.ie advertises long-term fixed rates of 3.4% for up to 30 years (Mortgages.ie payments calculator).

Do house repayment calculators include fees?

Standard repayment calculators typically show principal and interest only. Arrangement fees, valuation costs, and legal fees are separate—budget an additional €2,000 to €3,000 on top of your loan amount.

Can a house repayment calculator help first-time buyers?

Yes. Tools like AIB’s consider income and expenses to show an Approval in Principle figure (AIB mortgage calculator), while Permanent TSB’s first-time buyer calculator assumes a 3.70% fixed rate (APRC 4.52%) for €100,000 over 20 years.

What happens if rates change after calculation?

If you’re on a variable rate, your repayments will move with the European Central Bank rate. If you’re on a fixed rate, your repayment stays the same until your term ends. Moneycoach.ie estimates that a 1% rate rise adds €187 per month to a €300,000 mortgage.

Are house repayment calculators mobile-friendly?

Most major bank calculators—including AIB, Bank of Ireland, and EBS—work on mobile browsers. Independent tools like MoneySherpa.ie and Switcher.ie are also responsive.

How to factor in overpayments?

Use a tool like Mortgages.ie’s capital repayment and interest split calculator to model overpayment scenarios (Mortgages.ie tax relief calculator). Enter your proposed monthly overpayment to see revised totals and how many months you can shave off your mortgage.
