Why is my surrender value lower than the bonuses on my statement?
Bonuses shown on a statement are usually payable at maturity or on death. Paid in cash today, they are worth less.
Can my surrender value go down?
The guaranteed part doesn't. Non-guaranteed parts, such as any terminal bonus paid on surrender, can change when the insurer revises its bonus rates.
Where do I find the surrender value for each year?
In the benefit illustration you received when you bought the policy. It shows values at two illustrated rates of return; only the guaranteed column is certain.
When does surrender value pass the premiums paid?
It depends on the plan. For many endowments it is late in the term. Your benefit illustration shows the year.
