If there's a shortfall, you'll have to fill the gap by drawing down your savings or using a chunk of your nest egg to buy an annuity.2. Strive to pay off your mortgage. Do it before you retire and you'll cut your expenses significantly. But establish a home-equity line of credit first so that you'll have access to credit with tax-deductible interest. 3. Assess your savings and benefits. Get help from a financial planner or 401(k) investment counselor. Or crunch you own numbers at Fidelity Investments' myPlan, T. Rowe Price's retirement calculator or TD Ameritrade's WealthRuler. 4. Figure out how you'll cover health costs.
