One of the easiest ways to pre-pay for a funeral is to buy burial insurance (also known as funeral insurance). Instead of picking out details like caskets or cemeteries now, you simply set aside a lump sum that is payable out to your beneficiary upon your death. They can then use the money to fund your funeral in a way that fits with your wishes and their grieving needs.
Because burial insurance is a “guaranteed” payout (unlike car insurance, which will only pay out in the event of an accident, everyone will eventually die and collect on their burial policy), most of the costs are fixed. Your policy provider will take into account your age, your desired method of payment, and how large your payout is. From there, you will choose a policy that fits with your needs. This means that while one person (say, a 50-year-old in good health) might pay a fairly small monthly charge, another person (someone in their 70s who is a smoker) can expect larger monthly fees and even big upfront costs.
