### How are the interest rate and monthly payments calculated?

We use the same method used by other financial institutions to calculate the fixed monthly payments. The periodic payments are determined so that, for a given interest rate, the future monthly payments are equivalent to receiving back the investment today. GoParity uses the 30/360 day-count method.

In order to determine your monthly payment, we use the following formula:

Where:

• Value of investment: amount invested stipulated on the mutual agreement at the time of issuance.
•  r: the project's interest rate.
•  n : the number of payments per year.
•  t : the project's term, in years.

Why are interest payments not calculated using this formula?

Were we to use this formula, we would be assuming that the capital invested is only repaid at the end of the project's term, and not amortized throughout the project. As all our loans are amortized, this means that the capital is repaid throughout the project, and that the value of interest payments diminishes as the capital is amortized.
