In January 2025, the Public Finance Fuel Price Tracker updated its methodology for calculating the formula price of 92 Octane petrol and Auto Diesel. Below are some common questions regarding the fuel price formula, the reasons behind the change in methodology, and the key aspects and rationale for the adjustments made.
1. What is the Fuel Price Formula?
The purpose of the Fuel Price Formula is to:
The aim is to find the cost-reflective price, which is a fair accounting of the full cost of delivering fuel at the pump.
The cost-reflective price for the government owned entity should aim to cover all relevant costs of every aspect of operating the entity and would not add any extra profit margin, which would be relevant only if there was an investor who required a return on investment.
2. Why Implement a Fuel Price Formula?
In the past, local fuel prices often remained unchanged for several months. This practice led to two main issues:
To address these problems, it's important to align local fuel prices with world market prices. However, global prices are quoted in U.S. dollars per barrel and don't include additional costs like, processing, administration, and taxes.
3. What is the Fuel Price Formula based on?
The Fuel Price formula mentioned in the Publicfinance.lk is based on the fuel formula developed by the Ministry of Finance together with IMF’s assistance in 2018 (see link).
The formula is as follows;
Fuel Formula Price=V1+V2+V3+V4
Where:
V₁ = Landed Cost (Rs./Litre)
Which includes Singapore Platts Price per Barrel, Weighted Average Premium per Barrel, Loss due to the Evaporation and Exchange Rate (US$/LKR).
V₂ = Processing Cost (Rs./Litre)
Which includes Local Port Charges, Transport Cost, Dealer’s Margin including losses due to Evaporation to Dealers and Stockholding Cost.
V₃ = Administrative Cost (Rs./Litre)
Which includes Administrative Expenses including Personnel Cost, Depreciation, and other cost elements, if any.
V₄ = Taxation (Rs./Litre)
Which includes Customs Import Duty, Excise Duty, Ports and Airports Development Levy and any other taxes applied to fuel
4. How is the Fuel Price Formula calculated?
Based on the Ministry of Finance’s figures provided under each category (V1, V2, V3, and V4), the figures were reverse-engineered to be used in the formula. See below table on how each variable is obtained to be added to the table.

5. Why is the formula price of Public Finance.lk different from the formula price released by the Ministry of Energy?
The Ministry of Energy publishes a formula price through their “Pricing of Imported Refined Petroleum Products As Per The Pricing Formula.” However, the prices they report are slightly different from those on PublicFinance.lk. For instance, in November 2024, the Ministry of Energy listed the formula price of petrol at LKR 310.2 per litre, while PublicFinance.lk reported it as LKR 298.5 per litre. This results in a difference of LKR 11.7. (See table below for details)

The discrepancy between the Fuel Formula Price on PublicFinance.lk and that released by the Ministry of Energy arises mainly due to two reasons:
The Ministry of Energy includes extra components in its fuel price formula that are not present in the original formula developed by the Ministry of Finance. These additional variables are:
Note: The Stockholding Cost and Cost Savings from Refinery Production are not consistently applied every month.
The Ministry of Energy and PublicFinance.lk calculates certain cost components differently. Below is a comparison highlighting these discrepancies.

The main reason for the discrepancy in the same variables is that the Ministry of Energy adjusts its formula components monthly to reflect actual costs, including variables that may not be consistent with the original formula and is not publicly available (cost components only known by the CPC) . Therefore, this can introduce additional costs that are not accounted for in the original formula developed by the Ministry of Finance.
However, the ministry of finance press release clearly states
“According to the above pricing formula, Singapore Platts per Barrel and Exchange Rate are two uncontrollable variables. Other components are either controllable variables or fixed components”
This ensures that the formula remains reasonably cost-reflective without incorporating inefficiencies or ad-hoc cost changes. This methodology prevents additional costs arising from inefficiencies from being passed on to consumers.
6. What is the Revision in the Formula Price for Publicfinance.lk ?
Based on the reconciliation of the formula price of the Ministry of Energy, Publicfinance.lk has identified certain changes that may better reflect the current circumstances. And accordingly has incorporated the following changes to its fuel price mechanism.

7. Why are the other discrepancies not included in the Revised Formula Price for Publicfinance.lk ?
Publicfinance.lk has reviewed various discrepancies in the existing fuel pricing formula but has chosen not to include some of them in the revised formula. These excluded components are primarily additional elements that do not consistently reflect actual costs. The reasons for their exclusion are as follows:
