Continuous compound interest with additional transactions

SUMMARY

The discussion centers on calculating the yearly contributions required by the Sirius Cybernetics Corporation to meet a $10 billion pension fund target by 2030, assuming continuous compounding at rates of 10% and 12.5%. For a 10% growth rate, the yearly contribution is derived from the formula for continuous compounding, resulting in a specific annual payment. When the growth rate is adjusted to 12.5%, the required contribution decreases, demonstrating the significant impact of growth assumptions on financial planning.

1. The accountants at HR office of the Sirius Cybernetics Corporation have determined that the company would need additional $10 billion in its pension fund account over and above the current projected amount at the end of year 2030.

(a) Assuming the fund's balance will be growing, compounds continuously, at a rate of 10% a year, and the company will make regular contribution in 20 equal yearly installments over the 20-year period. How much is the company's yearly contribution?

(b) Not wanting to pony up the amount found in (a), the CFO of the company decides to "manage" (using a classic, but legal, way of gaming the accounting system in order to lower short-term expenses and, therefore, increase currently reported profit) the pension accounting by assuming a more aggressive 12.5% projected yearly growth rate, rather than 10%. How much is the company's would-be yearly outlay under the new growth assumption? Hint: In each case, solve the IVP with P(0) = $0; and then use P(20) = $10 billion to solve for the yearly contribution.
