While both offer flexible premiums and lifelong coverage, regular universal life policies grow at a fixed interest rate set by the insurer. In contrast, variable universal life allows you to invest the cash portion in subaccounts tied to market performance. This gives you more growth potential—but also more involvement. In financial centers like New York, Dallas, and Los Angeles, investors prefer VUL for its potential and adaptability. If you want a more active role in your policy’s performance, VUL may be a better fit.
