As part of his goal to get readers to save $1,000 in 30 days, personal finance blogger Ramit Sethi suggests setting up a personal fuel hedging fund to protect against rising petrol prices eating into your best intentions. His own method calls for figuring out what you were paying for petrol a month ago, setting up an automated bank sub-account, and transferring his monthly savings in gas costs to it. Setting a calendar reminder, he'll check the cost of fuel in three months, and pull from the fund if needed, or drop more in if prices fall. If you're not the type to save receipts, Sethi suggests an expense tracker like Mint to deliver your fuel costs to you. It's basically an advanced means of tricking yourself into saving money, but a worthy one. Photo by 'bert.
