Fixed vs. Index Pricing: Which Is Right for You?

Mid-market buyers face a choice when signing energy contracts: fixed or index pricing. Both have advantages and trade-offs. The wrong choice can mean overpaying during stable periods or being exposed during spikes. The right choice depends on your risk tolerance, cash flow needs, and market outlook.

Fixed Pricing

With fixed pricing, you lock in a rate for the contract term. This offers budget certainty and simplicity. For CFOs, it means predictability in forecasting. But fixed pricing often includes a premium — you pay for the supplier taking on risk. In falling markets, fixed buyers may feel stuck above the curve.

Index Pricing

Index pricing tracks the market, often monthly or hourly. You capture dips when markets fall but face exposure when they rise. For companies with flexible budgets or tolerance for volatility, index can save money. For those with thin margins, spikes can be dangerous without hedges in place.

Hybrid Structures

Block-and-index or collar structures combine elements of fixed and index. They allow partial budget certainty while leaving room for market advantage. These are often the sweet spot for mid-market buyers who need both resilience and opportunity.

Key Considerations

• Risk tolerance: Can your P&L absorb volatility?
• Cash flow: Do you need fixed budgeting for lenders or boards?
• Market view: Are you in a rising, falling, or volatile market?
