Gave at the office. Charitable donations made via payroll deductions are often overlooked tax deductions. There's no line on most W-2s for them, but pay stubs or receipts from recipients can prove your generosity.
Save with cash. Studies show that people may spend 50 percent more on fast food and other purchases when they pay with a debit or credit card, because parting with cash hurts more. Some retailers, including gas stations, offer discounts to cash customers to avoid paying the card "swipe fee" to a bank.
Pay yourself. Put an open jar in a conspicuous place in your home. When you do something you might have paid for — ironing, cooking, fixing a good latte — feed the jar with the amount you'd have spent. Do the same if you resist the impulse to buy something. The money will add up, fast.
Cut college costs. Make direct subsidized federal loans your first choice; they're easier to get, tend to be cheaper and there's no interest while you're in school at least half-time. Having loan payments automatically debited from your bank account can knock down your interest rate by a quarter percentage point or more.

Prepay. Adding a bit to your monthly payment can dramatically shorten the life of your mortgage and ultimately save you thousands of dollars in interest. Every extra dollar is applied to the loan's principal. Adding $10 per payment can prune 14 months from a 30-year, 5 percent mortgage for $100,000, and save you $4,500 in interest.
Drive a bargain. In many states you can cut your insurance rates if you have a monitoring device put in your car to verify low mileage or safe motoring habits. Or consider dropping your collision insurance if your car is old and not worth much.
