Frequently Asked Questions

What is the difference between equal installments and equal principal?

Equal installment (annuity) has fixed monthly payments with higher interest in the early stage — suitable for stable income earners. Equal principal has fixed principal payments with decreasing interest, resulting in lower total interest but higher initial payments.

How is the monthly mortgage payment calculated?

Equal installment: monthly = principal × monthly rate × (1+rate)^months ÷ [(1+rate)^months - 1]. Equal principal: monthly = (principal ÷ months) + (remaining principal × monthly rate). Use our calculator above for instant results.

Is early mortgage repayment worth it?

It depends on your mortgage rate vs. investment returns. If the loan rate exceeds your investment yield, early repayment makes sense. Also, with equal installments, interest savings are limited past the midpoint of the loan term.

What is the minimum down payment ratio?

Under current Chinese policy, the minimum down payment is generally 15-20% for a first home and 25-30% for a second home. Tier-1 cities may have higher requirements — check with your local bank.
