How it is calculated

Formula
debt × rate × days / days in year

Interest for every day of delay is added up. The total is rounded to kopecks once — at the end.

Rate by period
21 % → 20 % → 18 % …

The Bank of Russia key rate in force on each day is used — by effective date, not decision date.

Days and year
from the next day · 365 / 366

The delay starts the day after the due date and runs to the end date inclusive. A leap year divides by 366.

Payments
paid 30.06 → less debt from 01.07

A payment reduces the debt from the next day. No interest is charged on interest (Art. 395(5)).

Moratorium
01.04.2022 – 01.10.2022 → 0

For debts that arose before 01.04.2022, the moratorium days are excluded if the debtor was covered.

FAQ

The debt is multiplied by the Bank of Russia key rate and by the number of days of delay, then divided by the number of days in the year — 365 or 366. If the rate changed, the period is split by rate and the interest for each part is added up. The calculator does this itself, shows the formula of every row and rounds the total to kopecks once, at the end.
