Russian Mortgage Early Repayment Calculator
Calculate interest savings, compile a revised payment schedule, and compare term vs payment reductions.
What is the Russian Mortgage Early Repayment Calculator?
The Russian Mortgage Early Repayment Calculator simulates annuity home loan schedules in Russia and projects the financial impact of making extra principal payments. Due to high interest rates, making early payments (*досрочное погашение*) is a highly effective way to reduce overall interest charges. This calculator allows you to model a one-off or recurring prepayment and compare whether it is more beneficial to shorten your mortgage term (*уменьшение срока*) or reduce your monthly payment (*уменьшение платежа*).
How Does the Russian Mortgage Early Repayment Calculator Work?
Enter your current mortgage loan amount, annual interest rate, and remaining term in years. Input the amount of your planned extra payment and the month number in which it will be paid. Choose between reducing the monthly payment size or shortening the loan term to view your interest savings, new monthly payment, and how many months you shave off the mortgage.
Formula & Calculation Method
Monthly annuity is P × r(1+r)^n / ((1+r)^n - 1) where r is the monthly rate and n is the months. When an early payment E is made, it directly reduces the outstanding principal balance P. If reducing the payment, the monthly annuity is recalculated using the new balance over the remaining term. If reducing the term, the monthly payment remains constant, and the calculator simulates the schedule forward until the principal drops to zero.
Example Calculation
A 5,000,000 ₽ mortgage at an 18% interest rate for 20 years has a standard monthly payment of 77,046 ₽. Making a single early payment of 500,000 ₽ at Month 12: If reducing the term, your monthly payment stays at 77,046 ₽, but you save approximately 1,607,988 ₽ in total interest and shorten your term by 48 months (4 years). If reducing the payment, your monthly payment drops to 68,918 ₽, saving 862,604 ₽ in total interest with no term change.
