Funding vs Financing in PPPs: A Critical Distinction

Funding and financing are often used interchangeably, but in PPPs they mean very different things. Financing is the money needed upfront to build an asset. Funding is the money that ultimately pays for it over time. A PPP can bring in private financing, but the funding still comes from users or taxpayers. Confusing the two is one of the most common, and most costly, mistakes in PPP policy.

This article explains the difference between funding and financing in PPPs, why it matters, and how it shapes decisions about whether to use a PPP.

The definitions

The 2026 APMG PPP Certification Guide draws a clear line:

• Financing is the source of money required upfront to meet the costs of constructing infrastructure. In traditional procurement it usually comes from government surpluses or borrowing. In a PPP it comes from the private sector raising debt and equity.
• Funding is the source of money required to meet payment obligations over the long term, that is, to pay the private partner for its investment, operating costs and maintenance costs. Funding typically comes from taxes (in government-pays PPPs) or user charges (in user-pays PPPs).

Put simply, financing answers "who pays now?", and funding answers "who pays in the end?".

An illustration

Imagine a government needs a new hospital costing 200 million.

• Traditional procurement. Government finances the construction from its budget or by borrowing, and funds it, including repaying any borrowing, through taxes.
• Government-pays PPP. A private partner finances construction with equity and loans. Government then pays it an availability payment for 25 years, funded from taxes. The private partner uses those payments to cover operating costs, repay its loans and pay its investors.

In both cases, taxpayers fund the hospital. The PPP changes the timing of payments, who bears the risk and who manages the asset, not who ultimately pays.

Why the distinction matters

PPPs are not free money

Because a PPP brings in private financing, it can look as if the private sector is paying for public infrastructure. It is not. Private investors and lenders expect to be repaid with a return, from users or from government. A project that cannot be funded cannot be financed, however it is procured.

Fiscal commitments remain

A government-pays PPP may not appear as public debt in national accounts, depending on accounting rules. But the Guide is clear that it still creates a long-term commitment of public payments, explicit or contingent, that affects the government's fiscal position. Many countries cap their total PPP commitments for this reason. The article on whether PPPs create hidden public debt explores this in detail.

Private financing usually costs more

Private finance typically costs more than government borrowing. A PPP is only worthwhile if the efficiency gains from bundling, risk transfer and performance-based pay outweigh this extra cost. That is a value for money question, not a financing one.

Funding determines the PPP model

The funding source largely decides the type of PPP:

If users cannot or should not pay enough, government must fund the gap, and the project's affordability must be tested.

Other sources of funding

Beyond taxes and user charges, governments can use more specific funding sources. The Guide highlights land value capture. New infrastructure, especially transport, often raises the value of nearby property. Land value capture mechanisms, such as land value taxes, betterment levies and development impact fees, or public real estate development on land near a new line, aim to recover part of that increase to help pay for the infrastructure. Transit-oriented development projects, such as the Hyderabad Metro Rail in India, have used this approach.

Earmarked taxes, such as fuel levies dedicated to roads, are another example.

Where financing comes from in a PPP

In a private finance PPP, the project company typically raises:

• equity from sponsors and investors;
• senior debt from banks, bond markets or development finance institutions;
• sometimes mezzanine debt or public co-financing.

The structure, sources and instruments are covered in how PPPs are financed and PPPs as a financing mechanism.

Questions every government should ask

1. Who will fund this project over its life: users, taxpayers or both?
2. Can users afford the charges, and is charging them acceptable?
3. Can the budget afford the long-term payments, alongside all other PPP commitments?
4. Does private financing add value, through efficiency and risk transfer, that justifies its higher cost?

If the answer to the first three is unclear, the project is not ready for a PPP.

Key takeaways

• Financing is the upfront money to build an asset; funding is the long-term source of money to pay for it.
• PPPs can bring private financing, but funding still comes from users or taxpayers.
• A PPP that is not recorded as public debt still creates long-term fiscal commitments.
• The funding source shapes the PPP model: user-pays, government-pays or hybrid.
• Land value capture and earmarked taxes can supplement funding for some projects.
