Compound Interest Calculator for Shanghai

Savings accounts and deposits in Shanghai are priced off the People's Bank of China policy rate, which stood at 3% at the end of September 2026. National consumer price inflation was 0.90% in September 2026, so a saver earning exactly the policy rate would have a real return of 2.08% a year before tax.

Worked example for Shanghai

Start with CNY 50,000, add CNY 500 a month and use 3% compounded monthly. After 10 years you would have CNY 137,338 from CNY 110,000 of deposits; after 20 years CNY 255,189 from CNY 170,000. These amounts in Chinese yuan (renminbi) are only examples; real deposit rates offered by banks in Shanghai are usually below or above the policy rate depending on the term and the bank.

To see what that balance is worth in today's money, take inflation into account: at 0.90% a year, CNY 137,338 in ten years has the buying power of about CNY 125,568 now. Recent history for Shanghai's currency: 2020: 3.85% rate vs 2.6% inflation, 2021: 3.8% rate vs 0.8% inflation, 2022: 3.65% rate vs 1.9% inflation, 2023: 3.45% rate vs 0.2% inflation, 2024: 3.1% rate vs 0.2% inflation, 2025: 3% rate vs 0.0% inflation.

If you hold the money in a fixed deposit, the rate you lock in matters more than the compounding frequency. On CNY 50,000 over 10 years at 3%, switching from yearly to monthly compounding adds only CNY 272, while a rate 1 point higher adds CNY 7,074.
