when you apply for disability insurance the cost depends on your age health and risk of disability from your work this coverage can last many years and possibly your entire career you pick how long you want the coverage to last for example you may want it to last until you turn 65 when applying you decide what ability the insurance company has to adjust your coverage and premium cost 
if you choose a noncancellable insurance policy the insurance company agrees that it will not increase your premiums change your benefits or cancel your coverage over the life of the policy it doesn t matter if you develop health problems later or if your disability risk increases as you get older the coverage and costs stay the same throughout your policy 1alternatives to a noncancellable insurance policydisability insurance could also be guaranteed renewable if you buy a policy that is only guaranteed renewable the insurer must let you keep your policy as long as you pay your premiums however your premiums could go up as you get older the insurer is allowed to raise the premiums on a guaranteed renewable policy as long as the increase affects numerous policyholders and not just a particular customer 1 for example the insurer could increase premiums on everyone with your job or who is your age it couldn t increase your premiums because you as an individual get sick or hurt avoid purchasing a conditionally renewable policy also known as optionally renewable this allows the insurance company to raise your premiums or cancel your coverage if the insurer thinks the risk of insuring you has risen these policies put you at risk of losing coverage when you need it most and at a time when you may be unable to qualify for a new policy the insurer can change premiums and other policy conditions annually so this option provides the least beneficial arrangement for the insured noncancellable disability insurance provides the most stability however these policies charge a higher upfront premium than the other options 1noncancellable insurance and income changeanother benefit of a noncancellable disability insurance policy is that if your income decreases your coverage will stay the same if you were laid off from your office job and had to take up other work for less pay for example you would still be able to keep your insurance with a noncancellable policy most people don t have any guarantee that their income will never go down 2 under a noncancellable insurance policy even if someone s income decreases in the future such as when they are totally disabled the company will pay the total benefit from the original contract under a noncancellable policy even if someone changes jobs from a low risk white collar occupation to a riskier one such as a professional race car driver the company cannot decrease the insured s benefits 3
