Is 2.5% + $0.15 a Good E-Commerce Rate in 2026? (Real Math With Coastal Pay)

Let’s Define What a “Good” E-Commerce Rate Actually Means

A rate is not good or bad in isolation. It is good relative to what alternatives are offering for the same features, at the same volume, with the same all-in cost. Most merchants make the mistake of comparing headline percentages without accounting for flat per-transaction fees, gateway subscription costs, and other monthly line items that compound silently over the year.

The Four Components of True E-Commerce Processing Cost

• Percentage rate: Applied to each transaction amount (e.g., 2.5% of $100 = $2.50)
• Per-transaction flat fee: A fixed amount added regardless of transaction size (e.g., $0.15 per transaction)
• Monthly gateway fee: A recurring subscription for access to the payment gateway (can be $0 to $30+/month depending on provider)
• Add-on fees: Charges for specific features such as recurring billing, chargeback management, advanced fraud tools, or API access

Why the Flat Fee Matters as Much as the Percentage

On a $10 transaction, a $0.15 flat fee represents 1.5% of the transaction on top of the percentage rate. On a $200 transaction, that same $0.15 represents 0.075%. The flat fee hits low-ticket businesses hardest and becomes almost negligible for high-ticket stores. When comparing rates, always calculate the effective all-in cost at your specific average order value, not just the headline percentage.

What Coastal Pay’s 2.5% + $0.15 Includes

• Full Coastal Pay Gateway access at $0/month
• Apple Pay, Google Pay, Venmo, PayPal, Klarna, Afterpay, ACH, and Coinbase at the same rate
• 2,000+ e-commerce and software integrations
• Email invoicing, payment links, and virtual terminal
• No PCI surcharge, no statement fee, no API access fee

Here’s How 2.5% + $0.15 Compares to Every Major Flat-Rate Competitor in 2026

Rates based on publicly available standard pricing as of July 2026. Custom or negotiated rates may vary. Shopify plan costs represent platform subscription, not gateway fees.

The Key Takeaway From This Table

Coastal Pay’s $2.65 all-in cost on a $100 transaction is lower than every competitor’s standard rate. The Shopify Payments “Shopify plan” at $2.90 comes closest, but only because the merchant is paying $1,260/year in Shopify platform subscriptions. If you are already using Shopify, this is built into your plan cost. If you are not, Coastal Pay delivers a lower per-transaction cost at $0 monthly overhead.

What Is the Effective Rate at Different Average Order Values?

The effective rate is what you actually pay as a percentage of revenue – the most honest comparison number available. It accounts for both the percentage and the flat fee together.

Effective Rate Formula

Effective rate = (Rate x Transaction Amount + Flat Fee) / Transaction Amount

Coastal Pay 2.5% + $0.15 Effective Rate by Order Size

What This Tells You

The effective rate approaches the headline 2.5% as average order value increases. For e-commerce stores with average orders above $75, the effective rate is consistently below 2.7% – well below Stripe’s standard 3.2% effective rate at the same order sizes. For micro-transaction businesses (under $25 average order), the flat $0.15 raises the effective rate, and a processor with a lower per-transaction fee may be worth considering.

Here’s the Real Annual Cost at Five E-Commerce Volume Tiers

Numbers stop being abstract when you see them at your actual monthly volume. The following examples use 500 transactions per month as a baseline, with varying average order values to represent different e-commerce business types.

Volume Tier 1: $5,000/Month (500 transactions, $10 average order)

• Coastal Pay: 2.5% x $5,000 + $0.15 x 500 = $125 + $75 = $200/month
• Stripe: 2.9% x $5,000 + $0.30 x 500 = $145 + $150 = $295/month
• Annual savings vs Stripe: approximately $1,140

Note: At $10 average order, the flat fee represents a large portion of cost for both. Coastal Pay still wins due to the lower per-transaction fee ($0.15 vs $0.30).

Volume Tier 2: $25,000/Month (500 transactions, $50 average order)

• Coastal Pay: 2.5% x $25,000 + $0.15 x 500 = $625 + $75 = $700/month
• Stripe: 2.9% x $25,000 + $0.30 x 500 = $725 + $150 = $875/month
• PayPal: 2.99% x $25,000 + $0.49 x 500 = $747.50 + $245 = $992.50/month
• Annual savings vs Stripe: approximately $2,100
• Annual savings vs PayPal: approximately $3,510

Volume Tier 3: $50,000/Month (1,000 transactions, $50 average order)

• Coastal Pay: 2.5% x $50,000 + $0.15 x 1,000 = $1,250 + $150 = $1,400/month
• Stripe: 2.9% x $50,000 + $0.30 x 1,000 = $1,450 + $300 = $1,750/month
• PayPal: 2.99% x $50,000 + $0.49 x 1,000 = $1,495 + $490 = $1,985/month
• Annual savings vs Stripe: approximately $4,200
• Annual savings vs PayPal: approximately $6,980

Volume Tier 4: $100,000/Month (1,000 transactions, $100 average order)

• Coastal Pay: 2.5% x $100,000 + $0.15 x 1,000 = $2,500 + $150 = $2,650/month
• Stripe: 2.9% x $100,000 + $0.30 x 1,000 = $2,900 + $300 = $3,200/month
• PayPal: 2.99% x $100,000 + $0.49 x 1,000 = $2,990 + $490 = $3,480/month
• Annual savings vs Stripe: approximately $6,600
• Annual savings vs PayPal: approximately $9,960

Volume Tier 5: $500,000/Month (5,000 transactions, $100 average order)

• Coastal Pay: 2.5% x $500,000 + $0.15 x 5,000 = $12,500 + $750 = $13,250/month
• Stripe: 2.9% x $500,000 + $0.30 x 5,000 = $14,500 + $1,500 = $16,000/month
• Annual savings vs Stripe: approximately $32,400/year

At every volume tier from $5K to $500K/month, Coastal Pay’s 2.5% + $0.15 produces a lower monthly processing cost than Stripe’s standard 2.9% + $0.30, PayPal’s 2.99% + $0.49, and Square Online’s 2.9% + $0.30.

How Does 2.5% + $0.15 Compare When You Add the Gateway Fee Back In?

Many merchants compare processing rates without accounting for the monthly gateway fee – a line item that appears before any transaction is processed. Coastal Pay’s $0 gateway fee means the comparison above is already the all-in cost. For processors with a separate gateway subscription, the total overhead is higher than the per-transaction math suggests.

The $0 Gateway Fee Advantage Over One Year

A typical standalone gateway subscription runs $15 to $30/month. Many e-commerce merchants using Authorize.Net, NMI, or other gateway providers pay this on top of their processing rate.

• At $15/month: $180/year in gateway overhead before transaction one
• At $25/month: $300/year in gateway overhead
• At $30/month: $360/year in gateway overhead

When this gateway cost is added to a competitor’s per-transaction rate in the annual comparison, Coastal Pay’s advantage grows by $180 to $360 beyond the transaction-level savings shown above. For a merchant switching from a 2.9% + $0.30 processor with a $25/month gateway, the total annual advantage of Coastal Pay at $50,000/month is approximately $4,200 in transaction savings plus $300 in gateway savings = $4,500/year.

Platform Fees Are a Different Category

Shopify Payments includes processing at lower rates on higher Shopify plans, but the Shopify plan fee ($39 to $299+/month) is a platform cost, not a pure gateway fee. If you are already paying for Shopify for e-commerce features, the payment processing component is bundled into that value calculation. If you are evaluating Shopify purely for the payment rate, the effective all-in cost per dollar processed is often higher than Coastal Pay’s standalone 2.5% + $0.15 when the plan cost is amortized against volume.

Here’s When 2.5% + $0.15 Is Not the Most Competitive Rate Available

Being accurate about the limits of a flat-rate comparison is important. Coastal Pay’s 2.5% + $0.15 is highly competitive for most e-commerce merchants, but it is not always the lowest possible rate for every scenario.

When Interchange-Plus May Beat Flat-Rate

At very high volumes ($500K+/month) with a favorable card mix (mostly debit and standard consumer credit, few rewards or corporate cards), interchange-plus pricing can produce a lower effective rate than a flat 2.5%. Interchange on standard consumer debit can run as low as 0.9% to 1.2%, significantly below the 2.5% flat-rate baseline. If your business processes at high volume and you have visibility into your card mix, interchange-plus pricing via Coastal Pay’s enterprise program is worth discussing.

When a Higher-Percentage Processor Has a Unique Feature You Need

Stripe’s ecosystem has deep developer tooling, marketplace payouts via Stripe Connect, and sophisticated subscription management features. If your e-commerce business is deeply integrated into Stripe’s ecosystem and would require significant engineering time to migrate, the annual savings from switching may not justify the migration cost and risk. The break-even on a migration project depends on your engineering costs and current processing volume.

When ACH Can Lower Your Effective Rate Further

For e-commerce businesses with high average orders or B2B buyers, routing some transactions to ACH through Coastal Pay’s bundled ACH offering dramatically lowers the effective blended rate. A $500 B2B order on card at 2.5% + $0.15 costs $12.65. The same $500 via ACH costs $0.50 to $1.50. For stores with even 20% of volume eligible for ACH routing, the blended effective rate drops well below 2.5%.

What’s Your Breakeven? How to Calculate Your Own Savings Before Switching

Use this formula to calculate your annual savings from switching to Coastal Pay’s 2.5% + $0.15 before making any decision.

Step 1: Find Your Current Effective Rate

Pull the last 3 months of processing statements. For each month: divide total fees by total volume. Average the three results.

Effective rate = Total fees / Total volume

Step 2: Calculate What You Would Pay With Coastal Pay

Use your monthly volume (V) and monthly transaction count (T):

Coastal Pay monthly cost = (V x 0.025) + (T x $0.15)

Step 3: Calculate Annual Savings

Annual savings = (Current monthly fees – Coastal Pay monthly fees) x 12

Add: (Current monthly gateway fee x 12) if Coastal Pay eliminates this cost

Worked Example: Growing DTC Brand

• Monthly volume: $80,000
• Monthly transactions: 1,600 (average order $50)
• Current rate: Stripe 2.9% + $0.30
• Current monthly fees: $2,320 + $480 = $2,800
• Coastal Pay monthly fees: $2,000 + $240 = $2,240
• Monthly savings: $560
• Annual savings from rate: $6,720
• Gateway fee savings: $0 (Stripe has no standalone gateway fee)
• Total annual savings: $6,720

Worked Example: B2B Software Store

• Monthly volume: $120,000
• Monthly transactions: 400 (average order $300)
• Current rate: Authorize.Net gateway + processor at 2.7% + $0.10 + $25/month gateway
• Current monthly fees: $3,240 + $40 + $25 = $3,305
• Coastal Pay monthly fees: $3,000 + $60 = $3,060
• Monthly savings: $245
• Annual savings from rate: $2,940
• Gateway fee savings: $300
• Total annual savings: $3,240
