About Mortgage Calculators
A mortgage calculator is a tool used to calculate the finances involved for real estate loans known as mortgages. Mortgages are loans offered by banks or creditors which are secured by holding the properties title until the loan is fully paid.
Most calculators use a formula to calculate the total interest, interest charged per period, principal paid per period and total payments made. This formula is known as an amortization formula where it sets a fixed repayment schedule over a set period. The information or variables needed to calculate an amortizing mortgage are loan amount, time in months, interest rate and compounding frequency (monthly, bi-weekly or weekly).
Mortgage calculators used by lenders also determine fee costs, APR value of mortgage, points, applicant risk and applicant affordability.

History of Mortgages and Mortgage Calculators
Pre-1930's mortgages were paid over a short period (up to 10 years) and it wasn't until the 1930s the US government decided to step in and create departments to help the growing number of defaulted mortgages. The government decided to turn the non-amortizing mortgages into amortizing mortgages with a longer period term (20 years) with fixed payments of interest and principal .
After providing mortgages during this time the government created the federal housing administration, FDA to insure investors against defaulters. This security attracted investors to offer similar type mortgages to the public.
