Long term care insurance cost is anywhere around $1,000 to $7,000 annually as stated in http://www.ltcoptions.com/long-term-care-insurance-costs/ . However, you need to understand that the cost varies from one policy to another since it is tailored for the wishes and needs of the policyholder. A lot of people find this insurance product as expensive but its cost can still be modified through these factors: age, health, location and policy features like policy type, benefit amount, benefit period, elimination period and inflation protection.
The bottom line is this, there is no generic price tag for long-term care insurance. However, the said factors can dictate your rate. If you purchase early and you're healthy, then you'll get affordable rates. But if you decided to put this off later in your life, then you are at risk of paying for much higer rates.
