Note that both the words amortisation and mortgage share the Latin noun mors, which means death. When your debt amortises, it ensures your loan’s capital and interest balance is reduced to zero by the end of the term. Thus, amortisation is a characteristic often found in fixed-rate loans. The periodic payment is calculated based on these three factors, which is usually paid in monthly instalments. It’s an accounting technique used in loans that come with a specific loan amount (capital), interest rate, and term duration. Explaining AmortisationĪmortisation is the process of distributing payments evenly within an agreed term to pay off a debt. If you ever made any extra payments then you would run the calculation again with the new balance, but otherwise the balance on interest-only loans doesn't change as one is just paying the interest as it accrues. Interest Only Mortgage Payment = P x (r / n)Īs rates changed on an interest-only loan you could calculate new payments the same way using the above simple formula. The maths on interest-only payments is even easier. The subsequent year if rates changed again you'd insert the balance from the end of that year, shift the loan term from 20 years to 19, and insert the new interest rate.Įach calculation is easy, but doing it by hands dozens of times can get tiring. And each time rates reset you would do the calculation above. The above formula is for an amortising loan. £153,909.86 (balance from the orignal mortgage after 5 years of payments) at 3.6% APR (the new rate) loan over 20 years (25 years less the 5 years already paid) So, for example, if after a 5-year introductory rate of 3% the loan jumps to 3.6% you would calculate the new payments likeso: £450 x 2.11501955766 / (1.11501955766 ) = £853.58/moĪ person could do this calculation by hand, or use the calculator on our homepage to do it faster automatically.Įach time a mortgage's rate changes the above calculation begins anew. Here is the calculation for a 3% APR loan over 25 years n = number of payments per year (12 for monthly).r = mortgage interest rate as a decimal.Here is the formula for calculating regular amortising monthly repayments. Overall, understanding amortisation will give you a better grasp of planning your mortgage expenses. This ensures you receive favourable rates even after your initial fixed-rate mortgage is through. We’ll also touch on the importance of remortgaging your loan. Doing so allows you to pay off your mortgage earlier, which reduces your total interest expenses.
