Internet Bonding Costs 2026: What Does Failsafe Internet Really Cost?
Internet Bonding costs between €150-400/month for a typical SME. We show the complete cost breakdown, hidden costs, and when the investment pays off.
Zusammenfassung
TL;DR
Internet Bonding costs €150-400 per month for a typical SME in Austria. The costs consist of: hardware (€400-1,200 one-time), aggregator service (€60-180/month), and multiple internet lines (€80-250/month). The investment pays off after just one outage day per year for revenue-dependent businesses. Online shops, manufacturing plants, and medical practices typically recoup the costs within 2-6 months through avoided downtime costs.
Total Cost Overview
Internet Bonding is not a single cost item but a system of multiple components. Transparency about all costs is crucial for your budget planning:
| Cost Item | One-Time | Monthly | Annual |
|---|---|---|---|
| Bonding Router (Hardware) | €400-1,200 | - | - |
| Installation & Setup | €200-500 | - | - |
| Aggregator Service | - | €60-180 | €720-2,160 |
| Primary Internet Line | - | €40-100 | €480-1,200 |
| Secondary Internet Line(s) | - | €40-150 | €480-1,800 |
| Support & Maintenance (optional) | - | €0-50 | €0-600 |
| TOTAL | €600-1,700 | €140-480 | €1,680-5,760 |
Typical SME scenario (2 lines, basic hardware): One-time €800, monthly €180 (= €2,960 in the first year, then €2,160/year)
Cost Item 1: Hardware (Bonding Router)
The bonding router is the heart of your solution. It intelligently distributes data packets across all available WAN connections and coordinates automatic failover.
Price Ranges by Performance Class
| Device Class | Price | Max Throughput | Use Case |
|---|---|---|---|
| Entry-Level (SMB) | €400-700 | Up to 300 Mbit/s | Small offices, 1-10 employees |
| Mid-Range (Enterprise) | €800-1,500 | Up to 700 Mbit/s | Medium-sized businesses, 10-50 employees |
| High-End (Corporate) | €1,500-3,000 | Up to 1 Gbit/s+ | Large enterprises, production sites |
Common manufacturers in Austria:
- AlwaysOn by Werner.Solutions Balance Series: €500-2,000, proven solution with good support
- AlwaysOn RUTX Series: €300-600, price-performance winner with LTE
- AlwaysOn: €1,200-2,500, premium solution for enterprises
- MikroTik: €200-500, budget option for technically savvy users
Buy or Rent?
Many providers also offer hardware rental:
- Rental: €15-40/month (depending on device)
- Advantage: No initial investment, often includes support and replacement if defective
- Disadvantage: More expensive long-term (usually exceeds purchase price after 24 months)
- Recommendation: Rent for test phase (3-6 months), then buy if convinced
Cost Item 2: Aggregator Service
The aggregator is the server in the data center that reassembles your bundled packets and forwards them to the internet. This component is usually billed as a monthly service.
Pricing Models
Most providers charge based on bandwidth or flat rate:
| Model | Price | Included | Suitable For |
|---|---|---|---|
| Bandwidth Package S | €60-80/month | Up to 100 Mbit/s bundled | Small offices, branches |
| Bandwidth Package M | €100-140/month | Up to 300 Mbit/s bundled | Medium-sized businesses |
| Bandwidth Package L | €150-250/month | Up to 700 Mbit/s bundled | Large sites, production |
| Flat-Rate Unlimited | €180-300/month | Unlimited bandwidth | Data-intensive operations |
Additional Aggregator Costs
- Setup fee: €0-150 one-time (often waived with annual contract)
- Static IP address: €5-15/month (important for VPN servers)
- Premium support: €20-50/month (faster response times)
- Additional tunnels: €10-20/month per tunnel (for site networking)
Cost Item 3: Internet Lines
The ongoing costs for individual internet connections are the largest monthly expense. Cost optimization lies in cleverly combining different technologies and providers.
Typical Line Combinations and Costs
Scenario 1: Fiber + LTE Backup (ideal for cities)
- Fiber 250 Mbit/s (Primary): €50/month
- LTE plan 100 GB (Backup): €30/month
- Total bandwidth: Up to 350 Mbit/s
- Monthly costs: €80
- Reliability: High (different technologies)
Scenario 2: DSL + Cable + LTE (standard for rural areas)
- VDSL 100 Mbit/s (A1): €45/month
- Cable internet 150 Mbit/s (Magenta): €55/month
- LTE plan 50 GB (Drei): €25/month
- Total bandwidth: Up to 300 Mbit/s
- Monthly costs: €125
- Reliability: Very high (3 different providers)
Scenario 3: Two Fiber Lines + 5G (Maximum Performance)
- Fiber 500 Mbit/s (Provider 1): €80/month
- Fiber 250 Mbit/s (Provider 2): €60/month
- 5G plan Unlimited (Backup): €60/month
- Total bandwidth: Up to 810 Mbit/s
- Monthly costs: €200
- Reliability: Maximum (different providers + mobile)
Tips for Saving on Internet Lines
- Annual contracts: Often 10-20% cheaper than monthly cancellable plans
- Avoid business tariffs: Consumer tariffs are sufficient for bonding and significantly cheaper
- Mobile as backup: LTE/5G plans with low base fee + data package cheaper than second fixed line
- Own hardware: Avoid router rental from provider (€3-8/month per line)
Hidden Costs Often Forgotten
- Cabling: Multiple WAN lines mean more cables, possibly additional network outlets (€100-300 one-time)
- UPS (Uninterruptible Power Supply): Bonding router should keep running during power outages (€150-400)
- Monitoring: Proactive line monitoring (€10-30/month or via own solution)
- Administration effort: Initial setup and occasional adjustments (internal or external)
- Contract management: Managing multiple provider contracts
ROI Calculation: When Does Bonding Pay Off?
The crucial question: What does an internet outage cost you? For revenue-dependent businesses, bonding usually pays off very quickly.
Example 1: Online Shop (E-Commerce)
Parameters:
- Annual revenue: €500,000
- Daily revenue: €1,370
- Bonding costs: €220/month (€2,640/year)
- Average 2 outages per year without bonding (6 hours each = 0.5 days)
Calculation:
- Avoided downtime costs: 2 × 0.5 days × €1,370 = €1,370
- Bonding costs: €2,640
- Net costs: €1,270/year
- ROI: Break-even after 2.3 years if NO further outages are avoided
- BUT: Each additional avoided outage saves €685 - ROI achieved after just 3-4 outages
Example 2: Manufacturing with Industry 4.0
Parameters:
- Production value: €5,000/day
- Internet-dependent systems: MES, machine control, ERP
- Outage = production stop
- Bonding costs: €280/month (€3,360/year)
Calculation:
- 1 avoided outage day = €5,000 saved
- Bonding costs: €3,360/year
- ROI: Already achieved with first avoided outage (after about 8 months if historically 1x/year outage)
Example 3: Medical Practice with E-Card System
Parameters:
- 30 patients/day
- Average insurance share: €100/patient
- During internet outage: E-Card cannot be read, patients must be turned away or pay privately
- Bonding costs: €180/month (€2,160/year)
Calculation:
- 1 outage day = 30 patients × €100 = €3,000 revenue loss
- Plus: Dissatisfied patients, reputation damage
- Bonding costs: €2,160/year
- ROI: Already achieved after 1 avoided outage per year
Cost Optimization: How to Reduce Bonding Costs
1. Size Correctly
Not every business needs 700 Mbit/s. An honest needs analysis saves money:
- Small office (5 employees): 50-100 Mbit/s usually sufficient → choose cheaper lines
- Mid-size (20 employees): 150-300 Mbit/s → mid-range router sufficient
- Only prioritize business-critical applications: Use QoS instead of oversizing
2. Staged Implementation
You don't have to start with 3 lines right away:
- Phase 1: Primary line + 1 backup (LTE/5G) → Cost: €150/month
- Phase 2: After 6 months add second fixed line → Cost: €200/month
- This way you can test and have lower entry costs
3. Managed Services vs. Self-Operation
The choice between self-operation (DIY) and managed service (all-inclusive):
| Aspect | Self-Operation | Managed Service |
|---|---|---|
| Setup | Self or IT contractor | Provider handles everything |
| Hardware | Buy yourself (€800) | Included/rental |
| Monitoring | Set up yourself | Included 24/7 |
| Support | Troubleshoot yourself when issues arise | Hotline & remote support |
| Monthly costs | €140-200 | €250-400 |
| Suitable for | IT-savvy businesses | SMEs without IT department |
Rule of thumb: If you don't have IT staff in-house, managed service is usually cheaper than paying for external support during incidents.
Subsidies and Tax Deductibility
Tax Treatment
- Hardware: Immediate write-off up to €800 (low-value asset), above that 3-year depreciation
- Monthly costs: Fully deductible business expenses
- Installation: Immediately deductible as business expense
KMU.DIGITAL Subsidy
Internet Bonding can be subsidized under the KMU.DIGITAL program ("IT Security" module):
- Subsidy rate: 30% of costs
- Maximum: €5,000 subsidy
- Eligible: Hardware, installation, consulting (NOT ongoing costs)
- Example: Investment €2,500 (router + setup) → Subsidy €750
Important: Subsidy application must be submitted BEFORE project start. IT consultants can assist with the subsidy application.
Frequently Asked Questions About Bonding Costs
Are there hidden costs with Internet Bonding?
The most commonly "forgotten" costs are: UPS (€150-400), additional cabling (€100-300), and ongoing costs for multiple provider contracts. Reputable providers list all components transparently. Ask explicitly about setup fees, IP address costs, and support fees.
Can I start with cheaper hardware and upgrade later?
Yes, absolutely. Many businesses start with a MikroTik router (€300) and two lines. After 6-12 months, once bonding has proven itself, they switch to enterprise hardware (AlwaysOn by Werner.Solutions, AlwaysOn). Most routers have good resale value.
Is bonding worthwhile for home office too?
For self-employed people working from home, it can be worthwhile if outages directly lead to revenue loss (e.g., online consultants, freelancers with hourly billing). The costs are the same (€150-250/month). Many use fiber + LTE as the cheapest combo. Fully tax deductible.
What does it cost to switch back from bonding?
Practically nothing if you have monthly cancellable contracts. You can sell the hardware (about 30-40% value loss after 2 years). Aggregator services are usually cancellable monthly. The network operator needs to switch back to normal connection assignment (free, takes 2-4 weeks).
Can I install the hardware myself or do I need a technician?
Technically savvy users can do the installation themselves - most bonding routers have wizards. For SMEs without an IT department, professional installation is recommended (€200-500), which usually includes: cabling, configuration, QoS optimization, and training. This saves troubleshooting costs later.
Conclusion: Bonding is Cheaper Than One Day of Downtime
For most revenue-dependent businesses, Internet Bonding is not a question of cost but of risk avoidance. The investment of €150-400/month pays off with the first avoided outage day.
Total costs in the first year are €3,000-5,000 (with hardware purchase). From the second year, they drop to €1,800-3,600. Compared to the potential costs of an internet outage (revenue loss, production stop, reputation damage), that's manageable.
Our recommendation: Start with a test setup (2 lines, mid-range router, €200/month). After 3-6 months, you'll know if bonding is right for your business. Thanks to monthly cancellation periods, the risk is minimal.
