> The dream come true calculator works out how long it will take to save for something you want – a car, a trip, a home deposit – from what you have saved, how much you put away each month and the interest you earn, or how much to save each month to get there by a date.

## Inputs

- Price of your dream
- Current savings
- Monthly saving
- Annual interest rate (%)
- Target time (months)

## Results

- Time needed
- In years
- Interest earned
- Monthly saving needed for the target time

## Formula

```
Months to goal = log((goal + d/i) ÷ (savings + d/i)) ÷ log(1 + i)
Monthly saving for a deadline = (goal − savings × (1 + i)^n) × i ÷ ((1 + i)^n − 1)
```

## Explanation

Saving for a specific goal is easier when you can see the finish line. Automate a transfer on payday, and keep short-term goal money somewhere safe like a high-yield savings account.

### What each result means

- **In years** = [Time needed]÷12
- **Interest earned** = [Price of your dream] - [Current savings] - [Monthly saving]×[Time needed]

### Example values

How the main result changes when **Price of your dream** changes and everything else stays at the example values above:

## Worked example

Inputs — Price of your dream: $15,000; Current savings: $2,000; Monthly saving: $400; Annual interest rate: 4 %; Target time: 24 months.

Results — **Time needed = 30.4 months**; In years = 2.5; Interest earned = $829.31; Monthly saving needed for the target time = $514.52.

## FAQ

**How can I reach my savings goal faster?**
Increase the monthly amount, add windfalls and earn more interest.

**Where should I keep savings for a goal?**
A high-yield savings account or CDs for goals under ~3 years.

**Should I invest for a short-term goal?**
Generally not – markets can fall just when you need the money.

**What formula does the Dream Come True Calculator use?**
Months to goal = log((goal + d/i) ÷ (savings + d/i)) ÷ log(1 + i).
