There’s nothing quite like the feeling that you’ve made a sound investment choice that will not only earn you money, but will also see the world become a better place.

We’ve designed the MIRIS X platform to help our investors easily calculate the amount of interest they can earn on any investment amount at any given time. If, for example, you invest the minimum amount of €100 in a Green Bond on our platform, you’ll start earning interest immediately. Investors can log into their account on the MIRIS X platform to track the interest they are earning live. You can quite literally watch the numbers tick over every few seconds.

The 7% annual interest rate on our Green Bond is compounded monthly until it matures after three years. That means that you’ll also be earning interest on the interest you earned previously.

If an amount of €100 is invested in the green bond account with its annual interest rate of 7%, compounded monthly, the value of the investment after the 3-year term is up can be calculated as follows (bear with us, it's complicated but we believe in you)

P = €100. (Principle, this is your initial investment amount)

r = 7/100 = 0.07 (This is the 7% annual interest rate)

n = 12. (This is the number of times we compound per year. We compound each month and there are 12 months in a year.)

t = 3. (Duration of the investment in years.)

If we plug those figures into the formula, after 1 year we get the following:

A = 100 (1 + 0.07 / 12) (12 * 1) = €107.23

And this after 3 years:

A = 100 (1 + 0.07 / 12) (12 * 3) = €123.29

If there was no compounding this amount would be €100 (investment) x 0.07 (interest) = €7 (amount of interest earned after the first year)

Total earnings after 1 year = €107

Total earnings after 3 years = €122.50

This may not seem like a huge gain on €100, but it becomes substantial on €10,000 for example:

P = €10,000

r = 7/100 = 0.07

n = 12.

t = 3.

If we plug those figures into the formula, we get the following at the end of 1 year:

A = 10000 (1 + 0.07 / 12) (12 * 1) = €10,722.90

And this after 3 years:

A = 10000 (1 + 0.07 / 12) (12 * 3) = €12,329.26

The compounding effect becomes more and more noticeable as time goes on

If there was no compounding this amount would be €100 (investment) x 0.07 (interest) = €7 (amount of interest earned after the first year)

Total earnings after 1 year = €107

Total earnings after 3 years = €122.50
