The other aspects displayed in the table are calculated after the initial calculation. Contributions are added at the beginning of the calculation. Interest occurs annually.

for (var iteration: number = 0; iteration < this.iterations; iteration++) {
    var amount: number = (amount + this.contribution) * (1 + (this.interest_rate * 0.01));
