Life-insurance benefits should generate enough income after you die to fill in the gap between your family's cash requirement and its income from other sources.   This worksheet designed by San Mateo, Calif., money managers Thomas Bailard, David Biehl and Ronal Kaiser, authors of How to Buy the Right Insurance at the Right Price (Dow Jones-Irwin, 1989, $10.95), will help you figure out those needs.

3. Enter twice your monthly take-home pay as an emergency
    fund

Your Investment-rate factor Years until
spouse is 90

Rate Factor

Conservative Aggressive
How much annual income your life-insurance benefits will generate depends on whether you're the cautious passbook-account type or a more daring stock, bonds and real-estate player.  To complete step 8, above, go to the line that matches the number of years until your spouse turns 90 and then choose the "rate factor" that best describes your family's approach.

Note:  The conservative factor assumes 2 percent real annual growth, after inflation and taxes.  Aggressive growth assumes 4 percent.
