Ei = (1 + r1) ^ (n1/t) * (1 + r2) ^ (n2/t) * … * (1 + rn) ^ (nr/t)
The place:
– Ei = Efficient rate of interest
– r1, r2, …, rn = Anticipated rates of interest for every interval
– n1, n2, …, nr = Variety of durations for every rate of interest
– t = Whole mortgage time period in years

|border=”1px strong black”| 1 | 0.06 | 1 |
|border=”1px strong black”| 2 | 0.07 | 1 |
|border=”1px strong black”| 3-7 | 0.08 | 5 |
Ei = (1 + 0.06) ^ 1 * (1 + 0.07) ^ 1 * (1 + 0.08) ^ 5
Plugging within the numbers, we get:
Ei ≈ 1.06 * 1.07 * 1.08 ^ 5 ≈ 1.609
So, the efficient rate of interest for the mortgage is roughly 60.9%.
