At Simpli Finance, one of the most common questions we receive before a loan application is: what will my monthly repayment be? It sounds simple, but it has a significant bearing on whether a particular loan amount, term, and rate is actually viable for your business. Getting this wrong — borrowing too much or taking too short a term — is one of the most avoidable mistakes in business finance.
The calculator below gives you an instant repayment estimate for any combination of loan amount, term, and annual interest rate. Use it to model different scenarios before speaking to a lender. Understanding your numbers before you apply puts you in a much stronger position.
How to Use This Calculator
Set the loan amount to the figure you are considering borrowing. Set the term to the number of years you want to repay over — most business loans in Ireland run from one to seven years, though SBCI-backed facilities can extend to ten years. Set the annual interest rate based on the lender you are likely to approach: use 4–6% for SBCI loans, 7–12% for banks, and 6.5% for Microfinance Ireland.
The calculator uses a standard amortising loan formula — the same method used by most Irish lenders for fixed-rate term loans. This means each monthly repayment covers both interest and a portion of the principal, with the interest element reducing over time as the balance falls. The total repayable figure shown includes all interest over the full term.
Sample Repayment Table
| Loan Amount | Rate | Term | Monthly | Total Repayable |
|---|---|---|---|---|
| €25,000 | 6.5% (MFI) | 3 yrs | €767 | €27,612 |
| €50,000 | 8% | 3 yrs | €1,567 | €56,412 |
| €100,000 | 9% | 5 yrs | €2,076 | €124,560 |
| €250,000 | 4% (SBCI) | 7 yrs | €3,327 | €279,468 |
| €500,000 | 7.5% | 7 yrs | €7,598 | €638,232 |
What Affects Your Rate
Your actual interest rate will depend on several factors. SBCI eligibility is the single biggest rate reducer — if your business qualifies, always pursue SBCI-backed lending first. Beyond that, your CCR record, trading history, annual turnover, the purpose of the loan, and whether you are providing security all influence the rate a lender will offer.
Businesses with two or more years of clean trading, up-to-date Revenue Commissioners compliance, and consistent profitability will access the best rates from pillar banks. Businesses with shorter trading histories or imperfect credit histories will be offered higher rates or directed toward specialist lenders. A broker can assess your profile and identify which lender will offer the best rate for your specific circumstances.
FAQ: Business Loan Calculator Ireland
How accurate is this business loan calculator?
The calculator uses a standard amortising loan formula and is accurate for fixed-rate term loans. It does not account for arrangement fees, early repayment charges, or variable rate movements. Use it for ballpark planning — your actual repayment figure will be confirmed by the lender in a formal loan offer document.
What is a typical business loan interest rate in Ireland in 2026?
SBCI-backed loans start from 4% APR. AIB and Bank of Ireland typically charge 7.5–12%. Credit unions charge 6–9%. Microfinance Ireland charges 6.5% APR. Alternative lenders use factor rates rather than APR — a factor of 1.25 on a €50,000 loan means you repay €62,500 regardless of term, which equates to a high APR over a short term but is often appropriate given the speed of access.
Does taking a longer term always reduce my monthly payment?
Yes — a longer term reduces the monthly repayment amount, but increases the total interest paid over the life of the loan. A €100,000 loan at 8% over 3 years costs about €3,134 per month and €12,823 in total interest. The same loan over 7 years costs about €1,559 per month but €30,951 in total interest. Balance affordability against overall cost.
What is the debt service coverage ratio (DSCR) and why does it matter?
DSCR measures your ability to service debt from operating income. It is calculated as net operating income divided by total debt service (principal plus interest). A DSCR of 1.25 or above is generally required by Irish banks — this means your business generates at least €1.25 for every €1 of loan repayment due. Use this calculator to check your repayment and divide your monthly net income by it.
Conclusion
A business loan calculator is a planning tool, not a guarantee. The figures it produces are based on the inputs you provide, and your actual loan offer will depend on lender assessment, your CCR record, and the specific product you apply for. However, modelling your repayments before applying is essential — it tells you whether the finance is affordable and helps you have a more confident conversation with a lender.
