SD-WAN vs MPLS: A Real Cost Comparison for Multi-Site Enterprises

SpendWire Team•2 min read•November 11, 2026

MPLS circuits cost 3-5x more than SD-WAN alternatives. Here is an honest comparison with real pricing data.

If your enterprise is still running MPLS circuits to connect branch offices, you are likely paying 3-5x more than necessary. SD-WAN has matured into a reliable, secure alternative that delivers comparable performance at a fraction of the cost.

The Price Gap Is Real

MPLS Typical Pricing (2025-2026)

10 Mbps MPLS circuit: $800-1,500 per month per site

50 Mbps MPLS circuit: $2,500-5,000 per month per site

100 Mbps MPLS circuit: $4,000-8,000 per month per site

Average install lead time: 60-120 days

SD-WAN Typical Pricing

SD-WAN overlay on 100 Mbps broadband: $300-600 per month per site

SD-WAN overlay on 500 Mbps broadband: $500-900 per month per site

SD-WAN overlay on 1 Gbps broadband: $700-1,200 per month per site

Average install lead time: 14-30 days

Where MPLS Still Wins

MPLS is not dead, and there are legitimate use cases:

Ultra-low latency requirements (real-time trading, telemedicine)

Locations with only one broadband provider (no redundancy for SD-WAN)

Regulatory environments requiring dedicated private circuits

Legacy applications that cannot tolerate any packet loss

The Hybrid Approach

Most enterprises landing on the best cost outcome use a hybrid model: MPLS for 2-3 critical hub sites and SD-WAN for everything else. A 50-site enterprise running full MPLS at $2,000 per site pays $100,000 monthly. Switching 45 sites to SD-WAN at $500 per site while keeping 5 hub sites on MPLS drops that to $32,500. That is $810,000 in annual savings.

Hidden Costs to Watch

SD-WAN appliance costs: $1,000-5,000 per site (one-time or amortized)

Dual ISP circuits for redundancy: budget two broadband connections per site

Managed SD-WAN fees: $100-300 per site per month if outsourced

MPLS early termination fees: 50-100% of remaining contract value

How SpendWire Helps

Before committing to any WAN transformation, run your current MPLS invoices through an AI audit. We regularly find enterprises paying for bandwidth they upgraded from two contract cycles ago, circuits to closed offices still billing, and negotiable rate reductions buried in contract amendments. Cleaning up your current spend first makes the business case for SD-WAN even stronger.

Decision Framework

Choose MPLS if you need guaranteed SLAs with financial penalties for downtime. Choose SD-WAN if you need agility, bandwidth, and cost efficiency. Choose hybrid if you are like 80% of enterprises that need both.
