Answer

Use growing annuity formula assuming that the payments are made at the begining of each year and you pay in full for the year that you die (unfortunately). The value if you have an expected life of T years is:

[[math]]\begin{aligned} P V & = 750+ 750 *\left(\frac{1.05}{1.12}\right)+\cdots+ 750 *\left(\frac{1.05}{1.12}\right)^T \\ & = 750+ 750\left[\frac{1}{0.12-0.05}-\frac{1}{0.12-0.05} \times\left(\frac{1.05}{1.12}\right)^T\right]\end{aligned} [[/math]]

Solve for T . The breakeven point is T >= 16
