China Housing Fund Mortgage Explained: How a Housing Provident Fund Loan Beats the Bank Rate

If you work for a registered employer in China, a slice of your salary already disappears into something called the Housing Provident Fund (住房公积金, often shortened to 公积金). You contribute a percentage, your employer matches it, and the money sits in a personal account you barely think about. The reason it deserves a few minutes of your attention is simple: when you buy a home, that fund lets you borrow at a rate the commercial banks cannot touch. Most first-time buyers leave real money on the table because they never run the numbers. This post walks through what the fund is, why its loan rate is so low, how the loan ceiling is set, and how the monthly payment is actually computed.

What the Housing Provident Fund is

The fund is a mandatory savings pool. You and your employer each pay in a fixed percentage of your contribution base every month, and the combined balance accumulates in your name. You can withdraw it for housing-related reasons such as paying rent or repaying a mortgage, and once you decide to buy, you can borrow against the wider pool at a subsidized rate. It is not a bank product and it is not a government handout. It is a closed loop of contributors lending to each other, which is exactly why the interest is set so far below the open market.

Every city runs its own fund through a local management center (公积金管理中心). That decentralization matters: the rate is national, but the loan ceiling, the minimum contribution period, and the balance multiplier are all decided city by city. So the question "how much can I borrow" has a different answer in Beijing than in Hangzhou, and you have to check your own city before signing anything.

Why the fund loan rate is well below the bank rate

Here is the single number that explains the whole exercise. After the May 2024 rate cut, the fund loan rate for a first home on a term over five years is 2.85% (and 3.325% for a second home). A typical commercial first-home mortgage runs around 3.85% in the same period. That is roughly a full percentage point of difference, and on a long loan it compounds into something serious.

On a ¥1,000,000 loan over 30 years, that gap is about ¥190,000 of total interest between the fund rate and a commercial rate. The fund can offer this because there is no profit margin baked in: the pool is not trying to earn a spread for shareholders, it is recycling contributors' own savings. The trade-off is that the fund places a hard cap on how much it will lend, which brings us to the ceiling.

The loan ceiling is the smallest of three caps

This is the part most people get wrong. Your maximum fund loan is not one number, it is the smallest of three separate limits, and the calculator shows all three so you can see which one is biting.

The statutory city ceiling. Each city publishes a hard maximum. Beijing is ¥1.2M for a single contributor and ¥1.6M for a dual-contributor household with a child. Shanghai is ¥800k single and ¥1.6M dual. Shenzhen is ¥900k single and ¥1.8M dual. Guangzhou is ¥700k single. Hangzhou is ¥600k single. These are the figures the tool ships, sourced from each city's management center as of January 2025.
A multiple of your account balance. Most cities lend 10× to 20× your current account balance. If your real balance is low because of past withdrawals, this cap can quietly cut your ceiling in half.
The income cap. Your monthly payment generally cannot exceed about 50% of your contribution base. The tool reverse-engineers this into a loan-size limit too.

Whichever of the three is smallest is what the bank will actually approve. In a first-tier city the statutory ceiling usually bites first; in a smaller city with high contributions, the balance multiple often does. If your purchase price exceeds the ceiling, you borrow up to the cap from the fund and top up the rest with a commercial loan, a structure called 组合贷 (a combination loan). You always max out the fund portion first, because that is where the rate spread lives.

How the monthly payment is computed

Two repayment methods exist, and the choice changes your total interest by tens of thousands.

Equal installment (等额本息) keeps the monthly payment identical for the entire term. Early payments are mostly interest; later ones are mostly principal. The formula is the standard amortization one: payment = P × r × (1 + r)^n / ((1 + r)^n − 1), where P is the loan, r is the monthly rate, and n is the number of months.

Equal principal (等额本金) repays the same chunk of principal each month plus the interest on the shrinking balance, so payments start high and fall every month. It costs less total interest because the balance drops faster, but the early-year cash burden is heavier.

A worked example

Take a ¥1,000,000 loan, 30 years (360 months), at the first-home fund rate of 2.85%. The monthly rate is 0.0285 ÷ 12 = 0.002375.

Equal installment: the monthly payment lands at ¥4,135.57, every month, for 30 years. Total interest comes to ¥488,807.
Equal principal: the first month is ¥5,152.78, falling to ¥2,784.38 in the final month, with total interest of ¥428,687.

The equal-principal path saves about ¥60,000 in interest, but it asks for roughly 25% more cash in the early years. Most buyers pick equal installment for the predictable budget; equal principal is the right call only if you have comfortable buffer in the first few years and want the minimum total interest. The China Housing Provident Fund Loan Calculator lays both schedules side by side so this becomes a 30-second decision instead of a spreadsheet evening.

A note from running the numbers myself

When I first looked at my own contribution history, I assumed my account balance was just contribution base times rate times months. It was not. Years of small rent withdrawals had drained it, and the balance-multiple cap on my city was lower than I expected because of that. I had been mentally budgeting against the statutory ceiling, which was never going to be the binding line for me. Pulling the real balance statement from the fund portal first, then plugging the true figure in, changed my loan ceiling by a six-figure amount. That one check is the difference between a clean closing and scrambling for an extra commercial loan on signing day.

Run your own city before you sign

The fund mortgage is the cheapest financing most salaried buyers in China will ever qualify for, but the rules move every few months and they move differently in every city. Before you commit to a purchase price, confirm three things: your continuous contribution period meets the city minimum (usually 6 to 12 months at your current employer), your real account balance, and the second-home cap if it applies. Then run the binding ceiling and the blended monthly. If you are also weighing the bank route or a combination loan, compare the two side by side with the Mortgage Calculator, and if you are buying second-hand, the China Second-hand House Tax Calculator will tell you the transfer costs that sit on top of the loan. The listing price is not the number that decides whether you can afford the place; the monthly payment is.
