A policy illustration is the spreadsheet a carrier prints to show how a policy might perform over the decades. It's useful, and it's also the easiest place to get oversold. The biggest numbers on the page are projections rather than promises. Learning to read one takes maybe twenty minutes.
The first thing to find is that there are two sets of columns. The guaranteed column shows what the policy does if the company only ever does the least it promised. Guaranteed interest, no dividends, the worst charges allowed. The non-guaranteed column layers on assumed dividends or index credits and current costs, and it's always the rosier picture. Both are on the page on purpose. Only one is a promise.
So read the guaranteed column first, and ask yourself a blunt question. Would I be content owning this policy if this floor is all it ever does? If the answer is yes, you're looking at a policy built on a foundation you can live with, and any dividends are upside. If the guaranteed column looks thin and you're only excited by the projected one, slow down. You're being sold the weather, not the climate.
A few other checks. Check what rate the non-guaranteed column assumes, and ask yourself whether that rate looks rosy. Notice how internal costs behave in the later years. And be suspicious of any illustration whose whole appeal lives in the last, farthest-out rows, because those are the least certain numbers on the sheet.
Dividends and index credits aren't guaranteed. An illustration is a projection, not a contract. And policy loans cut your available cash value and death benefit until you pay them back. If you want a second set of eyes on how a policy is designed rather than just how it's illustrated, that's what Build a Life LOC is for.
