You first take the annual rate of interest in your mortgage and divide it by 365 to find out the quantity of curiosity that accrues every day.

Say you owe $10,000 on a mortgage with 5% annual curiosity. You’d divide that fee by 365 (i.e., 0.05 ÷ 365) to reach at a each day rate of interest of 0.000137.

Step 2. Determine Your Each day Curiosity Cost

You’d then multiply your each day rate of interest in Step 1 by your excellent principal of $10,000 (0.000137 x $10,000) to determine how a lot curiosity you’re assessed every day. On this case, you’re being charged $1.37 in curiosity every day.

Step 3. Convert it Right into a Month-to-month Quantity

You’re multiplying the each day fee by the principal and the quantity of curiosity that accrued the day gone by: $1.37.
