Should You Fix or Stay on the Variable Cap?
Scenario
Recommendation
Fixed deals available below forecast cap
Fix — you lock in a lower rate
Fixed deals higher than current cap
Stay on variable — benefit if prices fall
You want cost certainty
Fix — your rate won’t change for the fix term
You want flexibility
Variable — you can switch anytime without exit fees
You think prices will rise significantly
Fix now before rates go up
You think prices will fall
Stay on variable — the cap will drop to reflect lower wholesale costs

Tip: A fixed deal 5%–10% below the forecast cap is generally worth taking. A fix more than 10% above the current cap is usually not worth it unless you believe prices will rise significantly.
