10000*0.35%=35 yuan, that is, the monthly interest rate of 10,000 yuan is 0.35% in 35 yuan.

If the interest-bearing period is a whole month, the interest-bearing formula is: interest = principal × months × monthly interest rate interest-bearing period.

Extended data:

Banks can use product interest method and transaction interest method to calculate interest.

1. Accumulate the account balance daily according to the actual number of days, and multiply the accumulated product by the daily interest rate to calculate the interest.

The interest-bearing formula is: interest = accumulated interest-bearing products × daily interest rate, where accumulated interest-bearing products = total daily balance.

2. Transaction-by-transaction interest calculation method calculates interest one by one according to the preset interest calculation formula: interest = principal × interest rate × loan term.

There are three specific:

(1) If the interest period is a whole year (month), the interest formula is: interest = principal × year (month )× year (month) interest rate interest period.

(2) If there are whole years (months) and odd days, the interest-bearing formula is: interest = principal × number of years (months) × annual (months) interest rate+principal × odd days × daily interest rate.

(3) Convert the interest-bearing period into actual days to calculate interest. The interest-bearing formula is: interest = principal × actual days × daily interest rate.

These three formulas are essentially the same, but because the interest rate conversion is only 360 days a year, when calculating the actual daily interest rate, it will be calculated as 365 days a year, and the result will be slightly biased.

Which formula is used specifically, the central bank gives financial institutions the right to choose independently. Therefore, the parties and financial institutions can agree on this in the contract.
