SD-WAN vs MPLS: Total Cost Comparison Guide for 2026

MPLS vs SD-WAN cost comparisons dominate enterprise networking discussions as organizations evaluate whether to renew existing MPLS contracts or migrate to SD-WAN solutions. The decision has significant budget implications, with competing vendor claims making it difficult to determine which approach actually costs less.

The debate centers on fundamentally different pricing models.

MPLS networks deliver an all-inclusive managed service from a single ISP (private network connectivity, built-in quality of service, provider-managed hardware, and support) bundled into a single monthly fee per circuit. SD-WAN separates costs into distinct components: underlying internet connections (DIA, broadband, or other transports), SD-WAN technology and hardware, and management services, each potentially provided by separate vendors.

SD-WAN vendors claim savings of 20-70% compared to MPLS, while MPLS providers argue that SD-WAN's hidden costs eliminate the advantage once you account for all components.

Geography adds another layer of complexity. In North America, some organizations report 20% savings switching from MPLS to SD-WAN with DIA circuits. But in certain international markets, MPLS and DIA pricing converge, making SD-WAN more expensive rather than cheaper.

While MPLS vs SD-WAN pricing comparisons involve multiple variables (as you'll see throughout this guide), below is summary cost data comparing both approaches using pricing from the Lightyear dataset.

The Bottom Line: North America Cost Comparison

For a typical 1 Gbps circuit in North America, MPLS costs $1,439 per month. SD-WAN using DIA circuits plus managed service costs $1,066 per month. That equals about 25% savings with SD-WAN.

Here's the breakdown:

1 Gbps Circuit Example

The MPLS price includes everything: the private network, performance guarantees with low latency and minimal packet loss, managed hardware, and support. The SD-WAN price includes DIA circuits (which have similar SLA guarantees to MPLS) plus managed SD-WAN service.

The 25% savings holds true across North America for most deployments. But as you'll see in the sections below, this gap changes dramatically based on where your sites are located and what specific requirements you have.

Breaking Down SD-WAN Costs

SD-WAN costs split into two parts: underlying network connectivity and SD-WAN technology and service.

Component 1: Underlying Network Connectivity

Unlike MPLS (which is a single service), SD-WAN runs on top of whatever transport you choose. You pay for circuits separately.

Here's median pricing for North America circuits:

So, what's the difference between DIA and broadband?

DIA provides SLA-backed performance guarantees similar to what you'd expect from MPLS connections. You get committed uptime, low latency and delay, and minimal packet loss guarantees written into your contract. Network integrity is essential for mission-critical applications that can't tolerate performance degradation.

Broadband operates as a best-effort service with lower costs but no performance SLA. If your cloud-based applications can tolerate occasional latency or brief connectivity issues, broadband delivers substantial savings.

If you need predictable performance for voice, video conferencing, or real-time applications, DIA tends to be the appropriate choice.

You pay an “aggregator markup” when you purchase circuits through an SD-WAN provider rather than directly from service providers. This typically adds roughly 20% to your circuit costs.

So for example, let's say you're buying a $500 DIA circuit. Purchasing directly from AT&T costs $500. Purchasing through your SD-WAN provider costs $600 ($500 + 20% markup).

This markup buys you consolidated vendor management and unified billing across multiple carrier relationships. Instead of managing separate contracts, invoices, and support relationships with AT&T, Verizon, Lumen, and regional carriers, you deal with a single vendor who handles carrier coordination.

For organizations without dedicated telecom procurement staff, this simplification often justifies the premium. For teams with existing carrier relationships and telecom procurement processes, direct carrier purchases eliminate the markup.

Component 2: SD-WAN Technology & Service

On top of circuit costs, you pay for the SD-WAN overlay architecture itself. Modern SD-WAN solutions include built-in encryption to secure traffic across public internet connections, which MPLS traditionally handled through network isolation.

Managed or Co-Managed SD-WAN

Managed or co-managed SD-WAN typically starts around $100 per site per month. This includes hardware devices and appliances, software licenses, ongoing monitoring, and support. The price scales based on features you need, site size, and support level.

SD-WAN scales more easily than MPLS as you add locations. See our SD-WAN cost explainer for a detailed breakdown of pricing drivers.

DIY or Self-Managed SD-WAN

DIY or self-managed SD-WAN requires buying hardware upfront at roughly $1,000 per site. You'll also pay annual maintenance fees around $300 per site. This approach requires dedicated internal networking expertise to handle configuration, troubleshooting, and ongoing management.

For most organizations, managed SD-WAN makes more sense operationally. With this option, you don't have to build an internal team to manage SD-WAN deployments. The provider handles day-to-day operations while you focus on business requirements.

SD-WAN Cost Formula

Use this formula to calculate your total SD-WAN cost:

Total SD-WAN Cost = Circuit Cost + SD-WAN Service Cost

Breaking Down MPLS Costs

MPLS is sold as an all-inclusive package where one provider handles everything. A single MPLS fee covers private circuit connectivity between your sites, built-in quality of service guarantees, and service-level agreements (SLAs) for uptime and performance.

The provider manages hardware and firewalls at each location, handles end-to-end support and troubleshooting, and monitors your network continuously. That means you don't have to coordinate multiple vendors or manage separate components.

MPLS works this way because it requires carrier-managed infrastructure end to end. The carrier builds and maintains the private wide area network that connects your locations. Then, they provision circuits, configure routing, prioritize critical traffic, and guarantee application performance across their backbone.

The North American managed MPLS market represents $27.7B annually, with 4.4% growth projected through 2026. Despite SD-WAN growth, MPLS remains standard for organizations requiring guaranteed performance across distributed locations.

MPLS pricing is simpler but gives you less flexibility. SD-WAN pricing involves more complexity with multiple components, but it allows greater flexibility overall.

With SD-WAN, you can optimize each piece separately and get better visibility into network costs. Plus, you can choose cheaper broadband circuits for non-critical sites while using DIA for locations that need guaranteed performance.

When the Math Changes: Important Exceptions

Here are key scenarios where the standard pricing comparison shifts.

Exception 1: Markets Where MPLS = DIA Pricing

The 25% SD-WAN savings assumes MPLS costs more than DIA. But in some markets, they cost the same, eliminating SD-WAN's circuit cost advantage.

Carrier competition, regulatory requirements, and infrastructure development differ significantly by country. Markets with limited carrier options or heavy regulatory constraints often see MPLS and DIA pricing converge. In countries where carriers prioritize MPLS infrastructure over internet connectivity, DIA circuits can actually cost as much or more than MPLS.

Here's an example from a global customer deploying 100 Mbps circuits:

Global Customer in China (100 Mbps circuits)

When DIA and MPLS cost the same, SD-WAN adds incremental cost (roughly $100 per month for managed service) rather than delivering savings. Check pricing in each market where you operate. Don't assume uniform pricing across your deployment.

Exception 2: Legacy MPLS on Copper Infrastructure

Older MPLS deployments on copper face escalating costs as carriers sunset POTS infrastructure.

Carriers are actively phasing out traditional copper telephone lines that have supported connectivity for decades. As they decommission copper infrastructure, they're increasing pricing up to 10x to force customers onto modern fiber-based services. This affects MPLS customers still running circuits over copper rather than fiber.

As an example, say you have a site running 5 Mbps MPLS on copper at $340 per month. That works out to $70 per Mbps. Compare that to 100 Mbps DIA at $503 per month (roughly $5 per Mbps), a 14x price difference per megabit.

MPLS customers stuck on copper face either dramatic price increases or forced transition to new technology. If your carrier notifies you of copper sunset pricing changes, evaluate fiber-based MPLS or SD-WAN migration immediately rather than accepting the inflated copper rates.

Cost Scenarios at Different Bandwidth Levels

Use these examples to compare costs at various bandwidth levels.

Small and Medium Sites: 100 Mbps

For a typical 100 Mbps site, here's what you'd pay monthly:

Many organizations use a hybrid approach with broadband as their primary connection and DIA as backup for sites where brief outages are acceptable. SD-WAN intelligently routes traffic across the best available paths, creating secure VPN tunnels over both circuits. This configuration delivers cost savings while maintaining reasonable reliability.

But for business-critical locations like headquarters or central data centers, DIA as the primary circuit remains standard.

Large Sites and Data Centers: 1 Gbps

For high-bandwidth locations like on-premises data centers, the cost differences become more substantial:

Using DIA-backed SD-WAN saves you 25% compared to MPLS without sacrificing performance. Using broadband-backed SD-WAN saves 72%, though you're accepting a different performance profile without SLA guarantees.

The cost-efficiency of SD-WAN becomes clear as you scale.

For a 50-site deployment at 1 Gbps per site, SD-WAN with DIA saves $223,800 annually compared to MPLS. Scale that across enterprise networks with hundreds of locations and the savings become substantial enough to fund other infrastructure priorities.

What to Factor Into Your Decision

Consider total cost of ownership, management model trade-offs, geographic strategy, and circuit strategy to make the right decision for your business.

Total Cost of Ownership Considerations

Beyond monthly recurring costs, you need to account for several one-time and variable expenses.

Implementation and professional services fees vary by vendor but typically range from 10–20% of first-year costs. Circuit installation charges run $500 to $2,000 per site depending on location and access requirements. If you're self-managing SD-WAN, add roughly $1,000 per site for hardware purchases.

Contract length and early termination fees matter significantly. MPLS contracts typically run three to five years with substantial penalties for early cancellation. SD-WAN contracts are often more flexible, but underlying circuit contracts still bind you to term commitments.

Internal staff requirements differ dramatically between managed and self-managed approaches. DIY SD-WAN requires dedicated network engineering expertise. Calculate what those internal resources cost when comparing to managed services.

Management Model Trade-offs

Managed SD-WAN at roughly $100 per site per month puts the operational work on your provider, similar to MPLS. The provider handles day-to-day management, troubleshooting, and configuration changes. This works well for teams without deep SD-WAN expertise or organizations that want to avoid building internal SD-WAN capabilities.

Self-managed SD-WAN reduces telecom expenses to around $25 per month after initial hardware purchases. But you're responsible for deployment, ongoing configuration, troubleshooting circuit issues, and managing software updates. This requires internal expertise and dedicated staff time that may cost more than the monthly savings you're achieving.

Geographic Strategy

For multi-region deployments, calculate costs market by market rather than using global averages.

Verify MPLS versus DIA pricing in each specific country where you operate. In markets where MPLS and DIA cost the same, SD-WAN may increase your total costs rather than reduce them. Weight the savings or costs by the number of sites you have in each region.

A deployment that saves 25% in North America but costs 10% more in Asia might still deliver overall savings if 80% of your sites are in North America. But if your footprint is evenly distributed, the math changes completely.

Circuit Strategy With SD-WAN

Common hybrid approaches can significantly change your total cost calculation. Each one requires evaluating your application requirements, user expectations, and tolerance for potential outages against the cost differences between circuit types.

Primary DIA with backup broadband optimizes cost while maintaining reliability. You get SLA-backed performance for normal operations, with failover to best-effort broadband if the primary circuit fails. This approach works well for most business locations.

Dual DIA circuits maximize reliability at higher cost. Mission-critical applications at sites like data centers or headquarters often justify this configuration. 

Primary broadband with backup LTE or 5G wireless delivers the lowest cost and works for non-critical sites where occasional connectivity issues won't impact operations.
