⚠️ Tiered and time-of-use tariffs change the math. Per-kWh comparisons can mislead when standing charges differ — always model against your real kWh pattern.

Why this matters

Your headline bill hides three very different costs — the energy you actually used, the fixed charge for being connected, and the tax on top. Most "per kWh" marketing rates ignore the standing charge, which can make a cheap-looking tariff actually cost you more if your usage is low. Decomposing the bill lets you compare tariffs honestly and get real quotes on TUNA that match your consumption pattern.
