You want to be able to withdraw $50,000 from your account each year for 15 years after you retire.
You expect to retire in 30 years. If it earns 6% interest how much will you need to deposit each year to meet goal

This is a two-part problem that can be solved using the concepts of future value (FV) and present value (PV) of an annuity. Here's how we can approach it step-by-step:

### Step 1: Calculate the Present Value of the Withdrawals After Retirement
You want to withdraw $50,000 each year for 15 years after retirement. We need to calculate the present value of these withdrawals when you retire.

To do this, we use the formula for the present value of an annuity:

\[
PV = P \times \left( \frac{1 - (1 + r)^{-n}}{r} \right)
\]

Where:
- $P = 50,000$ (annual withdrawal)
- $r = 6\%$ (interest rate per year = 0.06)
- $n = 15$ (number of years for withdrawals)

This will give us the amount you need at retirement to support these withdrawals.

### Step 2: Calculate the Annual Deposits Needed to Reach the Retirement Goal
Once we know the total amount needed at retirement, we calculate how much you need to save each year for the next 30 years to reach that amount.

For this, we use the formula for the future value of an annuity (to find the annual deposit $D$):

\[
FV = D \times \left( \frac{(1 + r)^n - 1}{r} \right)
\]

Where:
- $FV$ is the amount we need at retirement (from Step 1)
- $r = 6\%$ (interest rate per year = 0.06)
- $n = 30$ (number of years until retirement)

Let me calculate this now.### Results:
1. The present value needed at retirement to support the 15 annual withdrawals of $50,000 is **$485,612.45**.
2. To meet this goal, you will need to deposit **$6,142.47** each year for the next 30 years at 6% interest.

Here are 5 related questions for further exploration:
1. How would the required annual deposit change if the interest rate were higher or lower?
2. What if you wanted to withdraw for 20 years instead of 15 years—how would that affect your annual savings?
3. What happens if you deposit a lump sum now instead of making annual deposits?
4. How does inflation affect the value of your withdrawals over time?
5. What would be the impact if you wanted to withdraw a different amount each year after retirement?

**Tip:** Starting to save early allows more time for interest to compound, reducing the annual amount you need to deposit.
