Quickly calculate the monthly interest payout and total interest for fixed-principal deposits. Supports various principal amounts, terms, and annual interest rates.
Total duration of the deposit in months. E.g., 1 year = 12, 3 years = 36, 5 years = 60.
How often interest is withdrawn (principal remains untouched). Number of Payouts = Deposit Term ÷ Payout Interval.
Bank's listed annual interest rate for this deposit type. E.g., 1.65 means 1.65%.
Please enter the principal, deposit term, payout interval, and annual interest rate to estimate periodic interest payouts.
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
This calculator models a deposit in Chinese yuan (CNY): the entered principal stays unchanged during the term, interest is estimated in equal payouts, and the principal is added back at maturity. It is a China-specific deposit model for English-reading users comparing a hypothetical payout schedule. It does not quote a bank’s current rate or convert the result to US dollars.
The form asks for principal in yuan, term in whole months, an interval of one, three, six, or twelve months, and a nominal annual rate entered as a percentage. “Nominal annual rate” here means the rate supplied by the user for this estimate; it is not an APY or an effective annual yield based on compounding.
For the selected interval, the tool calculates the interval rate as annual rate ÷ 100 × interval months ÷ 12. Each payout is principal × interval rate; estimated total interest is one payout multiplied by the number of payouts; maturity total is principal plus that estimated interest. Payout interest is not added to the principal to earn further interest.
P = principal in CNY; T = term in months; m = payout interval in months; r = annual rate entered as a percentGuide
Follow the workflow and verify inputs and outputs with practical examples.
Use a yuan amount for the one-time principal. Enter duration in months: for example, 36 means three years.
Select monthly, quarterly, semiannual, or annual to match the schedule you want to estimate.
Type the rate as a percent number. Enter 1.65 for 1.65%, not 0.0165 and not a monthly rate.
Review the payout amount, number of payouts, total interest, and maturity total. Change one input at a time to see which assumption changes the result.
Example: with ¥200,000, a 36-month term, a three-month interval, and a 1.65% annual rate, the interval rate is 1.65% × 3 ÷ 12 = 0.4125%. The estimated payout is ¥825, there are 12 payouts, total estimated interest is ¥9,900, and the maturity total is ¥209,900. These figures follow the calculator’s stated arithmetic before display rounding.
Use cases
See how the tool fits into real work and everyday tasks.
Enter a proposed principal and rate, then compare monthly and quarterly intervals to see how payout size and frequency differ while the assumed principal stays constant.
When a bank has supplied a rate and schedule, use those values to make a rough arithmetic check. Compare the estimate with the contract’s own calculation method before relying on it.
Q&A
Find concise answers to common questions and confusing cases.
No. The principal and displayed money amounts are in yuan (CNY), reflecting a China-specific deposit scenario. No exchange-rate conversion is included.
The calculation uses at least one payout. If the term is not an exact multiple of the interval, it rounds the payout count down and does not prorate the leftover months. Use a term aligned with the actual agreement when comparing results.
No. The model keeps principal unchanged and pays out interest separately, so it does not compound withdrawn interest.
No. Enter the rate shown by the institution for the relevant product and date; the page does not fetch offers.
Notes
Review scope, result limitations, and important precautions before use.
This is a simplified estimate, not a bank quote, account offer, or personalized financial recommendation. Product eligibility, available terms, interest accrual, payout dates, rounding, and early-withdrawal treatment depend on the institution and deposit agreement. The model does not handle day-count conventions, changing rates, taxes, fees, or holiday adjustments. Its two-decimal display can differ from a bank’s ledger calculation. Confirm the currency, rate, schedule, and maturity treatment with the institution before making a decision.
