## A calculus problem on continuous annuity with withdrawal.?

Show that a continuous annuity with withdrawal rate N = $5000/yr and interest rate r = 8%, funded by an initial deposit of Po= $75,000, never runs out of money.

As I understand the differential equation for this type of problem is

dP/dt = r (P-N/r)

For r, I should substitute 8/100 = 0.08. Is this correct?

This is how I solved the equation:

dP/(P – N/r) = r dt

ln(P – N/r) = rt + ln(C), where C is a constant

ln(P – N/r) – ln(C) = rt

ln[(P – N/r)/C] = rt

P – N/r = C e^rt

P = N/r + C e^rt

Substituting the given value of P at t = 0, we can find the value of C. I got C = $12500

P = N/r + 12500 e^rt

P = 5000/.08 + 12500 e^rt

P = 62500 + 12500 e^(.08t)

From the above equation, P > 0 for all values of t. Therefore the annuity never runs out of money.

Is my analysis correct?

What surprises me is the equation P = N/r + C e^rt

Since N is the withdrawal rate, should we not get an equation which shows that P decreases when N increases? But the equation P = N/r + C e^rt shows just the opposite.
