View calculation formula
Equal payment (annuity): monthly payment M = P·r·(1+r)n / ((1+r)n − 1), r = annual rate / 12, n = term × 12. The commercial and PF portions are each amortized at their own rate, then added together to get the combo monthly payment. Total interest = (sum of both monthly payments) × n − (sum of both principals).
Equal principal: month k = P/n + (P − (k−1)·P/n)·r. The two loans are computed month by month and added together to get the combo monthly payment. Total interest = (n+1)·P·r/2 for each loan, then summed.
All amounts are computed as integers in fen (cent of the yuan) to avoid floating-point errors, then converted to CNY for display.
❓ FAQ
What are the requirements for a combo loan?
The PF account must have been paid in full and continuously for 6–12 months or more, and you must meet the PF loan cap and home-purchase eligibility. The commercial portion is approved under the bank's requirements. The term and repayment date of the two loans usually stay consistent.
What if my PF quota is not enough?
Use the full PF amount you are eligible for first, and cover the rest with a commercial loan. You can first estimate your PF quota with the PF loan calculator, then use this tool to compute the combo monthly payment.
Which is more cost-effective: combo loan or pure commercial?
The PF rate (2.6% for first home) is significantly lower than the commercial rate, so a combo loan's total interest is usually lower than a pure commercial loan. Use this tool to automatically compare the total interest difference between the two plans.
Can a combo loan be repaid early?
Yes, but the commercial and PF portions must be prepaid separately. It is generally recommended to first repay the commercial portion with the higher rate; the exact terms follow the contract.
How long does combo loan approval take?
Both the PF center and the bank must approve separately, so the process takes about 2–4 weeks longer than a pure commercial loan. Complete documents and a good credit record can speed things up.
