PENALTIES AND LATE-FEE CALCULATOR 2026 — DAILY KEY RATE

Late-payment penalties for any debt: taxes and contributions per art. 75 of the Russian Tax Code (1/300 of the Central Bank rate for the first 30 days and 1/150 from day 31), injury-insurance contributions per Law No. 230-FZ (1/300 for every day), consumer-protection penalties (1% of the goods price or 3% of the service price per day, capped at the price), and contractual penalties per art. 330 of the Civil Code. Changes of the key rate over the period are supported. One HTML file, fully offline.

WHAT´S INSIDE:
• 5 modes in one tap: Tax Code art. 75, Law 230-FZ, consumer goods (art. 23), consumer services (art. 28), custom percentage
• Taxes: amount × rate ÷ 100 ÷ 300 for days 1-30, then ÷ 150 — the switch is shown in the table
• Injury insurance: 1/300 of the rate for every day, no step-up
• Consumer protection: 1% or 3% of the price per calendar day, capped at the price itself
• Custom percentage per art. 330 of the Civil Code — any contractual figure
• Key-rate changes: add dates and rates, each day uses its own applicable rate
• Period: from the due date to actual payment, or "up to today"
• The first day of delay is the day after the due date; calendar days are counted
• Period table: identical days are merged — dates, rate, day count and accruals
• Print the result to paper or PDF with one button
• Dark and light themes, large input fields, works offline

WHO NEEDS IT:
• Individuals — check penalty accruals on taxes and late fees on purchases
• Entrepreneurs and accountants — estimate penalties before paying an arrears
• Buyers — calculate the penalty for a delayed delivery or repair

EXAMPLE:
Arrears of 50,000 RUB, 45 days of delay, rate 21% → 30 days at 35.00 RUB (1/300) + 15 days at 70.00 RUB (1/150) = 2,100.00 RUB.

VERIFIED BEFORE SALE:
• 67 automated tests: the 1/300 → 1/150 rule at the 30-day boundary, mid-period rate changes, the consumer-protection price cap, calendar day counting across months and leap February, reversed dates
• 29 live browser tests: all 5 modes, data entry, period table, the consumer cap, adding and removing a rate period, rejecting negative amounts, persistence, themes
• Screenshots are from the real working program
