1. **Problem statement:** You want to find the annual income you can withdraw from your retirement savings over 23 years, given your total savings at retirement is $936264.0545 and you expect to live 23 years after retirement.
2. **Formula used:** To find the annual withdrawal amount $P$, we use the annuity payout formula for a present value $PV$ over $n$ years with interest rate $r$:
$$PV = P \times \frac{1 - (1 + r)^{-n}}{r}$$
Rearranged to solve for $P$:
$$P = PV \times \frac{r}{1 - (1 + r)^{-n}}$$
3. **Given values:**
- $PV = 936264.0545$
- $n = 23$ years
- Annual interest rate $r = 0.09$ (9% APR compounded monthly, but for withdrawals yearly, we use annual rate)
4. **Calculate $P$:**
$$P = 936264.0545 \times \frac{0.09}{1 - (1 + 0.09)^{-23}}$$
5. **Calculate denominator:**
$$1 - (1 + 0.09)^{-23} = 1 - (1.09)^{-23} = 1 - \frac{1}{(1.09)^{23}}$$
Calculate $(1.09)^{23}$:
$$ (1.09)^{23} \approx 7.031$$
So:
$$1 - \frac{1}{7.031} = 1 - 0.1422 = 0.8578$$
6. **Calculate $P$:**
$$P = 936264.0545 \times \frac{0.09}{0.8578} = 936264.0545 \times 0.1049 = 98188.5$$
7. **Interpretation:** You can withdraw approximately $98188.5$ per year for 23 years after retirement.
**Final answer:**
Your annual income during retirement is approximately **98188.5** per year.
