What the Margin Actually Is
Every Belgian business loan with a variable rate is priced as two components: a reference rate (almost always EURIBOR) and a margin. The reference rate moves. The margin is fixed for the life of the loan. On your term sheet it looks like EURIBOR 3M + 180bps or EURIBOR 6M + 2.25%. The number after the plus sign is the margin.
The margin is not a standard number. It is not derived from a published rate. It is the bank’s commercial pricing decision, applied specifically to your deal. Two companies borrowing the same amount from the same bank in the same week can receive margins 50 to 100 basis points apart. The reason is risk pricing, not rate fluctuation.
When people in finance talk about the “spread”, they mean the same thing. Spread and margin are used interchangeably in Belgian term sheets. The terminology difference is cosmetic.
Key takeaway: The margin is the part of your interest rate that is entirely within the bank’s control. EURIBOR moves with the market; the margin is a pricing decision made about you and your deal. That is why it is the part worth understanding, challenging, and negotiating.
How Banks Build Your Margin
Banks do not publish margin formulas. From the inside, however, the logic is consistent. A margin covers four things: the bank’s expected credit loss, the cost of regulatory capital, a liquidity premium, and the relationship discount (or premium) applied by the relationship manager.
Credit loss component. This is the core of the pricing. The bank assigns your company an internal probability of default (PD) rating. If your sector, leverage ratio, and cash flow coverage suggest a 1.5% annual default probability, the credit component of your margin will reflect that — roughly 120–150bps before capital charges. This number is generated by the bank’s internal rating model and is not visible to you.
Capital cost. Under Basel III and IV, every loan consumes a slice of the bank’s regulatory capital. Higher risk-weighted assets (RWA) mean more capital tied up, which has a cost. For SME loans, this is typically 20–40bps of the margin. Real estate-secured loans have lower RWA and therefore smaller capital charges.
Liquidity premium. The bank funds long-term loans with a mix of deposits and medium-term debt. The cost of that funding stack is not zero. On a 5-year term loan, the bank’s treasury will charge the lending desk an internal transfer price that reflects the liquidity cost of committing capital for five years. This adds roughly 15–30bps to the floor.
Relationship discount. This is the subjective component. A relationship manager who knows you, believes in your business, and wants to win the deal will argue internally for a lower margin. A manager who is pitching cold or managing risk exposure will not. This discretionary adjustment can move the margin 25–50bps in either direction.
Add these together and you get a pricing floor. The number on your term sheet is the floor plus the bank’s target return on equity for this deal type. You cannot negotiate below the floor. You can negotiate the excess above it.
Key takeaway: Belgian bank margins are built from credit loss pricing, capital cost, and a liquidity premium — then adjusted upward for return-on-equity targets and downward by relationship discount. The floor is driven by your PD rating. The negotiable range sits above it.
What Drives Your Basis Points
Understanding what inputs feed the bank’s model gives you a clear picture of which factors you can influence before the margin is set — and which you cannot.
Leverage ratio. This is the single largest driver of margin variation. A company at 2.5× Net Debt / EBITDA will receive a materially lower margin than a company at 4.5× for the same facility size. Every half-turn of additional leverage typically adds 25–50bps. If your deal has room to reduce the initial draw or improve the EBITDA figure presented, it is worth doing before the term sheet is issued.
Security package. Collateral directly reduces the bank’s loss given default (LGD), which feeds directly into margin. A loan with a first-ranking mortgage on commercial real estate will carry a lower margin than an unsecured cash flow loan of identical size. Hypothecary loans typically run 30–60bps below equivalent unsecured facilities.
Facility size. Larger loans carry lower margins. This is not generosity — it reflects that fixed costs (legal, structuring, monitoring) are spread over a larger base, and that larger borrowers typically have stronger credit profiles. The margin bands compress significantly above €5M.
Sector. Banks apply sector overlays to PD models. Real estate, healthcare, and food distribution tend to receive more favourable treatment than retail, hospitality, or construction, which are perceived as cyclically volatile. A 20–30bps sector premium is common in higher-risk industries.
Covenant package. A tight covenant package (DSCR, leverage ratio, liquidity minimum tested quarterly) effectively de-risks the loan from the bank’s perspective. Banks will sometimes offer a small margin reduction in exchange for additional covenants. This trade-off only makes sense if you are confident in headroom.
Number of banking relationships. A company that runs all its transactions, deposits, and treasury products through one bank gives that bank maximum ancillary revenue. The relationship manager can justify a tighter margin internally because the overall relationship is profitable. Spreading your banking relationships widely reduces this leverage.
Key takeaway: The five factors that move your margin most: leverage ratio, security package, facility size, sector, and depth of relationship. Of these, leverage and security are the most impactful and the most actionable before the term sheet is issued.
Margin vs. All-In Rate: What You Are Actually Paying
The margin is fixed. EURIBOR is not. Your actual interest cost — what you pay quarterly or semi-annually — is the sum of both, which means it moves every time your EURIBOR tenor resets.
The all-in rate on a variable loan is: EURIBOR [tenor] + margin%. If your term sheet specifies EURIBOR 3M + 200bps and the current EURIBOR 3M is 2.61%, your all-in rate today is 4.61%. When EURIBOR resets in three months, the margin stays at 200bps but the base shifts. If EURIBOR falls to 2.20%, your all-in rate becomes 4.20%.
On top of the interest rate, your true annual cost includes fees: the dossier fee (typically 0.5–1% of the facility, paid once at drawdown), the annual management or commitment fee (0.15–0.35% per year), and potentially a guarantee commission if personal or corporate guarantees are required. Annualised across the loan term, these fees can add 30–80bps to your effective cost. Two banks quoting the same margin may have very different total costs.
This is why comparison shopping requires calculating APR (annualised percentage rate, or JKP in Belgian regulation), not just comparing the margin number. Our term sheet guide covers how to calculate total cost including fees.
Key takeaway: Your effective annual cost is not your margin. It is EURIBOR + margin + annualised fees. A 200bps margin with a 1% dossier fee on a 3-year loan is closer to 230bps effective annual cost. Compare total cost, not just margin.
Benchmarking Your Margin Against the Market
Without a reference point, you cannot know whether your margin is standard, aggressive, or genuinely competitive. Belgian banks rely on borrowers not having that reference point. The ranges below are based on real Belgian SME lending data and reflect the spread of margins seen across hundreds of transactions, by facility size.

Indicative ranges. Actual margins depend on risk profile, security, and relationship.
A few notes on interpreting these ranges. The bands represent the market spread for typical Belgian SME term loans — not PE/LBO deals (which carry higher leverage and different covenant structures) and not real estate loans (which benefit from hypothecary security and carry lower margins). If your deal has significant real estate collateral, your margin should be at the bottom of the range or below it. If it is acquisition finance with high leverage, the top of the range or above is normal.
The median value is the more useful reference than the range floor. Banks price most deals at or above the median. A margin below the median typically requires either a very low-leverage profile, significant collateral, or a meaningful relationship discount.
Key takeaway: The market median for a Belgian SME term loan between €500K and €2M is approximately 2.75% above EURIBOR. Anything above 3.50% should prompt a direct question to your bank about their pricing rationale.
Margin Ratchets: When Your Margin Can Move
Most Belgian SME term loans carry a fixed margin for the life of the facility. But some — particularly larger transactions and PE-backed deals — include a margin ratchet: a mechanism that adjusts the margin up or down based on a financial metric, typically net leverage (Net Debt / EBITDA).
A two-way ratchet works in both directions. If leverage improves, the margin steps down. If leverage deteriorates, the margin steps up. Example: EURIBOR + 200bps at baseline (≤3.0× leverage), +25bps at 3.0–3.5×, +50bps above 3.5×. The leverage is tested at each covenant test date, and the margin applies from the next interest period.
A one-way ratchet — which only goes up — is a red flag. It means the bank gets margin protection when your performance deteriorates but you receive no benefit when it improves. Our red flags guide covers this specific clause in detail.
If your term sheet includes a ratchet, check three things: is it two-way or one-way? What is the baseline leverage assumed, and does it reflect your actual plan? And does the margin step-up align with any covenant threshold, or could you breach the ratchet without triggering a covenant event?
Key takeaway: A two-way ratchet rewards you for deleveraging. A one-way ratchet only protects the bank. If you see a ratchet, always check the direction. One-way ratchets are negotiable and in most cases should be removed or converted.
How to Negotiate Your Margin Down
The margin is one of the most negotiable elements of a term sheet. Banks expect pushback. The question is not whether to negotiate it, but how to negotiate it effectively.
The competing offer is your strongest lever. Nothing moves a bank faster than a competing term sheet with a lower margin. You do not need to have signed anything. A letter of intent or even a formal quote from another bank, showing a materially lower margin, gives your relationship manager the internal justification to go back to credit and argue for a reduction. Without a competing offer, the bank has no reason to move.
Benchmark data is the second lever. If your margin sits above the market median for your facility size, you can reference market data directly: “We have seen comparable transactions in the €1M–€2M range at 200–225bps. We would need you to be in that range to proceed.” Credia’s benchmark data exists specifically for this conversation.
Offer something in return. Banks respond to risk reduction. If you can offer stronger collateral, tighter covenants with more headroom than required, or a longer committed relationship (concentrating deposits or payments at this bank), the relationship manager can make the case internally. Framing the negotiation as “what would make this deal work at 175bps” is more productive than “your margin is too high.”
Know what is not negotiable. The credit floor is driven by the bank’s PD model for your company. You cannot argue below it. If a bank is at 225bps and the competitor is at 175bps, the 50bps gap may be genuine model difference or it may be one bank wanting the deal more. A gap above 75bps on comparable terms warrants a direct question about how the pricing was derived.
The negotiation guide covers the full sequence, including how to handle covenants and fees alongside margin. See our negotiate better loan terms guide for the complete playbook.
Key takeaway: The most effective margin negotiation combines a competing offer (forces the bank to respond), benchmark data (gives them internal justification), and a risk offset (gives them something to take back to credit). Use all three if possible.
What to Check on Your Term Sheet
When you see a margin on a term sheet, four things are worth verifying before signing:
1. Is it expressed consistently? Belgian term sheets express margins as either a percentage (e.g. 2.00%) or basis points (e.g. 200bps). Both mean the same thing. Occasionally you will see a term sheet that states the margin and the all-in rate separately — verify that the arithmetic is correct and that the all-in rate matches EURIBOR + margin with the current reference rate.
2. Is it fixed or does it contain a ratchet? If the margin is fixed, confirm the wording says “fixed margin” or “margin shall not change during the term.” If there is a ratchet clause, identify whether it is one-way or two-way and verify the leverage bands match your financial projections with headroom.
3. Does it apply to the full facility or vary by tranche?On multi-tranche deals (e.g. term loan A + revolving credit facility), each tranche typically carries a different margin. This is normal but requires separate benchmarking. An RCF margin is usually 10–25bps higher than the equivalent term loan margin (you are paying for optionality).
4. Is there a commitment fee on undrawn amounts? On revolving facilities and capex lines, banks charge a commitment fee on undrawn portions — typically 30–50% of the margin. This is charged quarterly, regardless of whether you draw the facility. On a €1M undrawn RCF with a 200bps margin, a 40% commitment fee costs €8.000 per year for the right to draw. Factor this into your true cost calculation.
Key takeaway: The four checks: margin expressed correctly and matching the arithmetic, fixed vs. ratchet (and if ratchet, which direction), per-tranche vs. uniform, and commitment fees on undrawn amounts. All four affect your actual cost.
FAQ
What is a basis point?
One basis point (1bps) equals 0.01% of the loan principal per year. A margin of 200bps is 2.00%. On a €1.000.000 loan, 1bps costs €100 per year in additional interest. When comparing margins across lenders, even 25bps can represent thousands of euros over a 5-year term.
Why does the margin not appear in my ECB rate charts?
EURIBOR and ECB policy rates are published daily and are publicly observable. Your margin is a bilateral commercial agreement between you and your bank. It is not published anywhere and cannot be inferred from market data — which is exactly why benchmark datasets like Credia's are valuable.
Can the bank change my margin after the loan is signed?
For most Belgian term loans, no. The margin is contractually fixed at signing. The bank can only change the margin if the agreement contains a ratchet clause or a re-pricing provision — both of which must be explicit in the term sheet. If there is no ratchet and no repricing clause, the margin cannot move.
My bank says 250bps is "standard for my profile." Is that true?
250bps is at or above the market median for most Belgian SME term loans up to €2M. Whether it is appropriate for your profile depends on your leverage, security package, and sector. "Standard" is a framing device banks use. The correct response is to ask what specific risk factors are driving the margin and to request a comparison against their recent deals for comparable profiles.
What is a typical margin for a Belgian SME acquisition loan?
Acquisition finance carries higher margins than regular working capital or investment loans, because leverage is typically higher and the collateral is thinner. For a Belgian SME acquisition at 3.5–4.5× leverage, margins of 275–375bps above EURIBOR are common depending on security and sector. Above 4× leverage, 350–450bps is not unusual.
Should I focus on the margin or the all-in rate when comparing offers?
Compare total cost: (EURIBOR + margin) × loan amount + annualised fees, calculated over the expected life of the loan. The all-in rate today reflects a specific EURIBOR level that will change. Two offers with the same all-in rate today but different margins will diverge if EURIBOR moves. Know both numbers.
