FAQ

How is the monthly payout calculated?
It uses the amortization formula: Payout = P·r·(1+r)^n / ((1+r)^n − 1), where P is the principal, r is the monthly rate (annual ÷ 12 ÷ 100), and n is the number of months. The principal is fully depleted by the end of the term.
What is the total payout?
The total amount paid out over the entire term — the monthly payout multiplied by the number of months.
Does it work for a 0% annuity?
Yes. At 0% the monthly payout is simply the principal divided by the number of months.
