This calculator estimates the potential growth of your Indexed Universal Life (IUL) policy's cash value based on compound interest. It uses hypothetical annual interest rates.

Understanding Indexed Universal Life (IUL) and Compound Interest
Indexed Universal Life (IUL) insurance policies offer a unique combination of life insurance protection and cash value growth potential. A key feature of IULs is how their cash value grows, often linked to the performance of a stock market index (like the S&P 500), but with crucial safeguards.
How IUL Cash Value Growth Works:
The interest credited to an IUL policy's cash value is typically determined by the performance of a chosen stock market index over a specific period (often a year). However, this growth is subject to two important provisions:
Cap Rate: This is the maximum interest rate your policy can earn, regardless of how high the index performs. If the index has a stellar year, your interest is capped at this predetermined percentage.
Floor Rate: This is the minimum interest rate your policy will earn, even if the index performs poorly or declines. This protects your cash value from market losses. A common floor is 0%, meaning you won't lose money due to market downturns.
The Power of Compound Interest in IULs:
Compound interest is the process where your earnings also start earning interest. It's often described as "interest on interest." In an IUL, this compounding effect can significantly accelerate the growth of your cash value over time, especially when credited interest is reinvested year after year.
The formula for calculating compound interest typically looks like this for a single sum:
A = P (1 + r/n)^(nt)
Where:
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (as a decimal)
n = the number of times that interest is compounded per year
t = the number of years the money is invested or borrowed for
In the context of an IUL, the calculation is more dynamic. The interest credited each year depends on the index's performance, the cap, the floor, and the policy's specific crediting method. For simplicity, this calculator uses a hypothetical average annual rate, capped and floored, applied to the growing cash value annually.
Using the IUL Compound Interest Calculator:
This calculator helps you visualize the potential long-term growth of your IUL cash value. By inputting your policy details and hypothetical interest rate scenarios, you can:
Understand the impact of different interest rate assumptions.
See how the annual cap and floor rates can influence your growth.
Project the potential cash value accumulation over your desired time frame.
Disclaimer: This calculator is for educational and illustrative purposes only. It uses hypothetical rates and does not guarantee future results. Actual IUL policy performance can vary significantly and depends on the specific policy contract, the performance of the chosen index, insurance costs, fees, and the insurance company's financial strength. Consult with a qualified financial professional for advice tailored to your individual circumstances.
