// Calculation Logic
// 1. Calculate General Rates: Valuation * (Cents / 100)
// Note: Rate is usually cents per dollar of valuation.
// Example: 0.25 cents per dollar = $0.0025 per dollar.
var baseRates = valuation * (rateCents / 100);
// 2. Calculate Discount
// Discounts usually apply to the General Rates portion, sometimes capped.
// For this estimator, we apply it to the base general rates.
var discountAmount = baseRates * (discountPct / 100);
// 3. Total Calculation
var totalPayable = baseRates + charges – discountAmount – rebate;
// Prevent negative totals

Understanding QLD Council Rates
Council rates in Queensland are a property-based tax charged by local government councils (such as Brisbane City Council, Gold Coast City Council, or Sunshine Coast Council) to fund essential community services and infrastructure. Calculating your expected rates can be complex as it involves several variables set by both the state government and your local council.
How the Calculation Works
The primary component of your council rates bill is the General Rate, which is calculated based on the unimproved value of your land. This value is determined by the Queensland Valuer-General, not by the real estate market price of your home (which includes the building).
The formula generally follows this structure:
Land Valuation ($): The official value of your land.
Rate in the Dollar: A multiplier set by the council. It is often expressed in "cents." For example, if the rate is 0.25 cents, you pay $0.0025 for every dollar of land value.
Fixed Charges: These are flat fees added to every bill, regardless of land value. Common charges include waste collection services, the State Emergency Management Levy (EML), and environmental levies.
Cents in the Dollar Explained
When you look at your rate notice, you will often see a figure referred to as the "Differential General Rate." This is the "cents in the dollar" figure. It varies depending on how you use the land (e.g., owner-occupied residential, residential rental, commercial, or rural). Owner-occupied properties typically attract the lowest rate in the dollar compared to investment properties or commercial land.
Discounts and Rebates
Most Queensland councils offer an Early Payment Discount. This is typically a percentage (often around 5%) deducted from your General Rates if you pay the full amount by the due date.
Additionally, pensioners may be eligible for subsidies. The Queensland Government offers a state-wide pensioner rate subsidy, and many local councils offer an additional remission on top of that to further reduce the cost of living for retirees.
Why Do Rates Change?
Your rates may increase if the Valuer-General increases the official valuation of your land. However, many councils use "averaging" (smoothing the valuation over 3 years) or "capping" (limiting the percentage increase from one year to the next) to prevent sudden, sharp spikes in your annual bill.
