Four key facts summarise the Irish car loan market in one table.

• Variable rate: 6.5% APR for electric/plug-in hybrid cars, 7.1% APR for petrol/diesel (Bank of Ireland official site).
• Fixed motor finance: 5.85% APR for BEVs, 6.3% APR for other cars (Bank of Ireland motor finance page).
• Sample repayment: €20,000 over 5 years at 7.1% APR = €394.71/month, total €23,682.60.

Credit union car loans

• Clane/Leixlip CU: standard car loan 7.76% APR, PCP Buster 5.5% interest (5.64% APR) (Clane/Leixlip Credit Union).

0% finance deals from dealers

• Rare in Ireland; often limited to specific models, high deposit required, and short terms.
• Not standardised; check individual dealer offers. No 0% APR loan from a bank or credit union.

The implication: borrowers who are already credit union members can secure significantly lower rates than those who must use a bank or online lender.

Which bank offers the cheapest car loan in Ireland?

Bank of Ireland rates

• Variable: 7.1% APR petrol/diesel, 6.5% APR EV/plug-in hybrid.
• Fixed motor finance: 5.85% APR BEV, 6.3% APR others.

AIB car loan rates

• Representative rates vary, typically 7–10% APR according to Switcher.ie.
• Quick online decision and repayment calculator available on AIB website.

An Post car loan rates

• An Post Money offers personal loans for cars; rates advertised around 7.9% APR (variable) as of last check.

Credit union rates compared

• Credit unions often beat banks: e.g., CLCU 5.64% APR, Kilcock 5.07% APR, Affinity 4.95% APR.
• But you must be a member (usually easy to join).

The pattern: credit unions lead on headline rates, but banks offer broader eligibility and faster approval. For most borrowers, the cheapest loan will come from a credit union if you can join.

How do I use a car loan calculator to compare costs?

AIB car loan calculator

• Visit AIB’s loan page, enter loan amount, term, and see indicative monthly repayment.
• Example: €15,000 over 5 years at 8% APR gives approximately €304/month.

Credit Union car loan calculator

• St. Francis Credit Union calculator lets you choose weekly, fortnightly, or monthly repayments.
• Example: €10,000 over 5 years at 7.5% variable interest (7.78% APR) = €200/month.

Bank of Ireland car loan calculator

• On the Bank of Ireland car loan page, enter amount and term to see repayment estimate.
• Sample: €20,000 over 5 years at 7.1% APR = €394.71/month.

Bonkers car loan calculator

• Comparison site Switcher.ie (formerly Bonkers) aggregates rates from multiple lenders and provides a calculator.

What this means: using a calculator is not just helpful—it’s essential to avoid overpaying by hundreds of euros.

What is the difference between a car loan from a bank and a credit union?

Eligibility criteria

• Banks: open to all residents with good credit history.
• Credit unions: require membership (usually a small savings account and a €1 minimum share).

Interest rate differences

• Credit unions: typically 4.95%–8.2% APR, capped at 12.68% APR.
• Banks: 6.5%–10% APR depending on lender and car type.

Loan terms

• Both offer 1–7 years. Credit unions may offer more flexible terms.

Approval speed

• Banks: often same-day decision online.
• Credit unions: may take 1–3 days depending on loan amount and board approval.

The trade-off: lower rates at credit unions vs. faster, simpler process at banks. If you’re a member of a credit union, it’s almost always cheaper.

Are there any 0% finance car deals available in Ireland?

Which cars offer 0% finance?

• 0% finance is rare in Ireland. It occasionally appears on select new models (e.g., some Hyundai, Kia, or electric vehicles) through manufacturer deals.
• No bank or credit union offers 0% car loans.

Conditions of 0% offers

• Usually require a high deposit (30–50%), short term (2–3 years), and limited to specific models.
• Often tied to PCP (Personal Contract Plan) rather than a standard loan.

Comparison with low-rate loans

• A 0% deal on a €30,000 car over 3 years saves about €2,500 in interest compared to a 7% APR loan.
• But if the 0% car has a higher purchase price, the saving may be offset.

What this means: 0% finance is a genuine opportunity but comes with strings. Compare total cost, not just the interest rate.

Three lenders, one clear leader for lowest rates.

How to use a car loan calculator – step by step

1. Choose a lender’s calculator (e.g., Bank of Ireland, St. Francis CU).
2. Enter the loan amount you need (e.g., €15,000).
3. Select the loan term (e.g., 5 years).
4. Note the APR shown (if not adjustable, check the lender’s rate page).
5. Read the monthly repayment and total cost.
6. Compare across at least three lenders.

The outcome: a few minutes of calculator work can save you hundreds of euros by revealing the true cheapest option.

The cheapest car loan in Ireland today is almost certainly from a credit union – but only if you can join one. For borrowers who prefer a bank, Bank of Ireland’s fixed motor finance at 5.85% APR for electric cars is a strong alternative. For everyone else, the key takeaway is to use a car loan calculator, compare APRs side by side, and read the terms carefully. For a typical buyer financing €15,000 over 5 years, the difference between a 5% and 8% APR is about €1,000 in extra interest. The choice is clear: join a credit union if you can, or negotiate the best fixed rate from a bank.
