WebThe Fisher equation says that these two contracts should be equivalent: (1 + i) = (1 + r) × (1 + π). As an approximation, this equation implies i ≈ r + π. To see this, multiply out the right-hand side and subtract 1 from each side to obtain i = r + π + rπ. If r and π are small numbers, then r π is a very small number and can safely be ignored.
