How to Figure Monthly Interest Payments In Your Head

Negotiations with borrowers can be tricky and fast-paced. The workout professional needs to be able to respond to borrower inquiries quickly, authoritatively and without losing a step. While final numbers, covenants, terms and conditions must be developed carefully before being finalized, workout professionals know that Cash is King and that they must be able to deal with cash flow issues on the fly.

The workout professional who can make quick rough calculations without using his or her HP 12C has an advantage. A desperate borrower may promise you the moon just to buy time. An unsophisticated borrower may not know how much cash is available to pay the Bank and still keep the business operating. A complicated relationship with multiple deals may prove challenging for Bank and borrower, particularly where the borrower lacks an experienced CFO or controller and financial reporting is incomplete. The officer who can quickly comprehend whether borrower promises are realistic can keep the conversation moving without having to stop to run detailed calculations.

Let’s assume you have a $1,000,000 loan that bears annual interest at 6 percent. You need to know how much interest accrues each month. Here’s the simple rule of thumb to follow:

Always start your calculations by assuming that the simple annual interest rate on the loan is 12 percent, or 1 percent per month.

So the first easy calculation is that interest on a $1,000,000 loan at 1 percent per month results in monthly interest of $10,000 per month.

But your loan bears interest at only 6 percent, which is half of 12 percent. The second easy calculation is to cut the monthly payment in half to $5,000 per month.

Similarly, if the interest rate is 8 percent, multiply the monthly payment by two-thirds, because 8 percent is two-thirds of 12 percent. Thus, the monthly interest payment on $1,000,000 at 8 percent is $6,667 per month.

Precision is not the goal here. Approximation allows you to keep the conversation moving. There will time later to do the exact calculations, which of course must be done before the deal is finalized.

You can apply this process to rough approximations of fully amortized loan payments, but it does get tricky. As any homeowner knows, payments on a loan amortized over 30 years includes precious little principal paydown in the early years, but this is not so for loans that fully amortize over shorter time periods. It is worthwhile committing to memory a few formulas for calculating fully amortized loan payments that you can use in your head.

At today’s low interest rates, to fully amortize a loan over 3 years requires payments of around $30 per $1,000 of principal. So to fully amortize the payment on our $1,000,000 loan over 3 years at 6 percent will require monthly payments of about $30,000. The exact payment is $30,421.94, so to be safe, after making your calculation, refer to the monthly payment as a little more than $30,000. If your interest rate is slightly higher or lower, adjust your calculations accordingly.

There are magic numbers for 4 and 5 year fully amortized loans, also. To amortize a 6 percent loan over 4 years requires payments of about $25 per $1,000. To amortize a 6 percent loan over 5 years requires payments of about $20 per $1,000.

Finding loan amortization payments in not something that many people can do without a calculator, but there is a simple table that you can keep for handy reference for those times when you do not want to stop the negotiations to calculate specific payment amounts. Before the age of pocket calculators and online loan calculators, amortization tables were published in books and on wallet-sized cards. Even in our electronic age, these tables can be valuable tools for workout professionals to use in borrower negotiations. We have reproduced the table below:

To use the amortization table, just multiply the payment factor by the number of $1,000 of loan principal.
