Counting up to your target

Reaching a savings goal is a race between your deposits, a little help from interest, and the size of the target. The calculator steps forward month by month, adding interest and your deposit until the balance crosses the goal.

each month: balance = balance × (1 + rate ÷ 12) + deposit

Interest does some of the work, especially as the balance grows, so the total you deposit is a little less than the goal. The gap between the two is the interest earned along the way.

Worked example

To reach $10,000 starting from $1,000, saving $250 a month at 4% interest takes about 34 months — roughly 2 years and 10 months — with interest covering around $600 of the total.

Reaching it sooner

The monthly deposit is the biggest lever by far — interest helps, but consistent saving does the heavy lifting. Automating the transfer on payday is the simplest way to keep the projection honest.

Worth keeping in mind

  • Deposits beat rate. For most goals, how much you add matters more than the interest.
  • Starting balance helps. A head start shortens the timeline and earns interest from day one.
  • Plan in today’s money. Remember inflation when the goal is years away.

Frequently asked questions

How is the time worked out?
The calculator grows your balance month by month — adding interest and your deposit — until it reaches the goal, then reports how many months that took.
Is interest compounded?
Yes, monthly. The annual rate is divided by twelve and applied each month, so earlier deposits earn a little interest that helps reach the goal sooner.
What if my deposits can’t reach the goal?
If the balance cannot grow toward the target — for example with no deposits and no interest — the calculator will indicate that the goal is not reached within a long horizon.
Does this account for tax or inflation?
No. It is a simple before-tax projection in today’s money. Real returns vary, and inflation erodes future value, so treat it as a planning guide.
