Here is the step-by-step breakdown of the logic:

1. Get User Inputs: The function first reads the Principal Amount, Age, and Gender you selected.
2. Establish a Base Rate: I set a starting “base factor” for the minimum age (55) for both males and females. This is the estimated monthly payout per $100,000.
   • BASE_MALE_FACTOR_55 = 502.5 ($502.50)
   • BASE_FEMALE_FACTOR_55 = 495.0 ($495.00)
3. Adjust for Age (The Core Logic):
   • The code then “ages up” from 55 to the age you entered, adding a small amount to that base factor for each year.
   • This increase isn’t the same every year; it gets larger as the person gets older, just like in the real world. I broke it into tiers (55–64, 65–69, and 70+).
   • For example, for a 65-year-old male, it starts at $502.50 and adds the annual increase 10 times (from 55 to 64) to arrive at the correct factor for age 65.
4. Scale by Principal:
   • After the loop, we have an ageAdjustedFactor (e.g., $643.50 for a 65-year-old male). This is the correct payout for $100,000.
   • To make it work for your principal, it calculates a principalFactor. If you entered $100,000, the factor is 1.0. If you entered $250,000, the factor is 2.5.
   • principalFactor = principal / 100000;
5. Calculate the Final Payout:
   • It multiplies the age-adjusted factor by the principal factor.
   • finalPayout = ageAdjustedFactor * principalFactor;
   • (e.g., $643.50 × 2.5 = $1,608.75)
6. Display the Result: The final number is formatted as currency (e.g., $1,608.75) and shown on the page.
