Graph 1 • Balance and Deposits Over Time The solid curve includes estimated interest; the dashed curve shows contributed cash.

Graph 2 • Deposits vs. Estimated Growth Shows the makeup of the projected balance.

Graph 3 • Projected Balance vs. Goal Compares the balance at the estimated target time with the entered goal.

Summary: Estimated balance after 24 months is $15,005.80.

Summary: At $500.00 per month and an assumed 3% annual return, you could reach $15,000.00 in about 24 months. Interest is compounded monthly and deposits are made at month end.

⚠️ Returns are assumptions, not guarantees. Taxes, fees, and changes in deposit timing are not modeled.

Formula & Mathematical Methodology: Savings Goal Calculator

Bₙ = Bₙ₋₁ \times (1 + r) + d

$B$ : Savings balance after a monthly period
$r$ : Annual return divided by 12
$d$ : Monthly deposit made at period end

Rounding: Currency values display to two decimal places; whole items round up where required.

Worked Example: $2,500 saved, adding $500 monthly toward $15,000

Estimate time to a savings target with a modest assumed return.

Apply the monthly return assumption to the starting balance.
Add the planned deposit at the end of each month.
Repeat until the target is reached.

Result: The goal is reached in about 24 months.
