Turn any goal into a monthly savings plan. Enter the dream, its cost today, your timeline, existing savings, and what you can set aside each month. The tool inflates the cost, grows your current savings, and calculates the required monthly contribution. You also get a progress bar, milestone months, and a full schedule. See your plan in seconds.
Big goals often feel out of reach until they are broken into monthly steps. This Dream Come True Calculator helps you do exactly that. It is built for anyone saving toward a specific target: a home down payment, a wedding, a car, a business launch, or an early retirement fund. Instead of guessing whether your monthly savings are enough, you enter the numbers and see the gap between where you are and where you need to be. The calculator factors in inflation so the goal cost is realistic at the target date, and it applies an expected return so your existing savings and future contributions can grow. Everything runs in your browser, and the results update as you adjust the inputs. Use it to test scenarios, set a realistic monthly transfer, and track milestones along the way.
Choose your currency from the dropdown; the tool changes symbols only and does not convert amounts.
Name your dream in the text field, such as “New Car” or “Emergency Fund.”
Enter the cost today, using today’s prices rather than an inflated guess.
Set the timeline in months, from 1 to 600.
Add any amount you have already saved toward the goal.
Type the monthly amount you can realistically set aside.
Adjust the expected annual return on savings and the inflation rate.
Press Calculate to refresh the required monthly amount, projected balance, progress bar, milestones, and schedule.
Formula: Goal at target date = Cost today × (1 + Inflation rate)^(Months ÷ 12)
Formula: Grown current savings = Already saved × (1 + Annual return)^(Months ÷ 12)
Formula: Gap = max(0, Goal at target date − Grown current savings)
Formula: Required monthly = Gap × monthly rate ÷ ((1 + monthly rate)^Months − 1), when monthly rate > 0
Formula: Required monthly (zero return) = Gap ÷ Months
Formula: Projected balance = Already saved × (1 + monthly rate)^Months + Monthly affordable × (((1 + monthly rate)^Months − 1) ÷ monthly rate)
Formula: Months needed (with return) = log((Goal + Monthly affordable ÷ monthly rate) ÷ (Already saved + Monthly affordable ÷ monthly rate)) ÷ log(1 + monthly rate)
The monthly rate is the annual return divided by 12. The calculator compounds your current savings and each monthly contribution. It also inflates the goal cost month by month using the monthly inflation rate. If the monthly return is zero, the formulas fall back to simple division or addition. The required monthly amount is the payment needed to close the gap between the inflated goal and your grown current savings.
Imagine you are planning a $50,000 wedding in 36 months. You have $5,000 already saved, and you can put away $1,000 per month. You expect a 5% annual return and 3% inflation.
First, the goal at the target date: $50,000 × (1 + 0.03)^3 = $54,636.35. Your current savings grow to $5,000 × (1 + 0.05)^3 = $5,788.13. The gap is $54,636.35 − $5,788.13 = $48,848.22.
The monthly rate is 0.05 ÷ 12 = 0.0041667. Required monthly = $48,848.22 × 0.0041667 ÷ ((1.0041667)^36 − 1) = $1,259.63.
Your actual monthly contribution of $1,000 produces a projected balance of $5,000 × (1.0041667)^36 + $1,000 × (((1.0041667)^36 − 1) ÷ 0.0041667) = $5,788.13 + $39,336.03 = $45,124.16. That is about $9,512 short of the $54,636 goal.
The calculator would label this a shortfall and suggest adding roughly $260 per month or extending the timeline. If you increase your monthly savings to $1,260, you land almost exactly on target. The milestone cards would show when you cross 25%, 50%, 75%, and 100% of the goal under your chosen plan.
It inflates the goal cost month by month using the annual inflation rate divided by 12. The goal at the target date is higher than today’s cost, which means you need to save more. Setting inflation to zero keeps the goal at today’s price.
Use a conservative estimate based on where you keep the money. A savings account might earn 0–1%, while a diversified portfolio might average 4–7% over long periods. Higher return assumptions lower the required monthly amount, but they also carry more risk.
Yes. Enter the timeline in months, from 1 to 600. The calculator compounds monthly and inflates monthly, so it works for short goals like a vacation or a holiday fund. The schedule table shows monthly rows when the timeline is 24 months or less.
The projected balance is what you would have if you contribute your chosen monthly amount. The goal at target date is what you need. If your projected balance is lower, you have a shortfall. If it is higher, you are ahead of schedule.
The milestone cards show the dollar amount for 25%, 50%, 75%, and 100% of the inflated goal. They also show the month when your projected balance crosses each threshold. If a milestone is not reached within your timeline, the card shows “Not within” your timeframe.
It compares your monthly contribution to the required monthly amount. If you contribute at least 105% of the required amount, you are ahead. Between 98% and 105% is on track. Between 70% and 98% is slightly short. Below 70% is a shortfall.
The calculator handles one dream at a time. For multiple goals, run separate calculations and add the monthly amounts together. You can also use the copy button to save each plan for comparison.
No. It uses a single expected return rate and does not subtract taxes, fees, or expense ratios. If your investments are in a taxable account, your after-tax return may be lower than the rate you enter.
The calculator still shows the required monthly amount and the goal at the target date. Your projected balance will only include the growth of your existing savings. The months-needed calculation will show that the goal is not reachable without contributions.
Yes. The schedule table recalculates whenever you change an input. It shows contributed amount, interest earned, balance, goal, and percentage of goal for each period. For timelines longer than 24 months, it shows year-end snapshots plus the final month.
Interest is calculated monthly on the current balance using the monthly return rate. Each month, the balance grows by the interest and your contribution. The interest earned column is cumulative, so it shows the total interest accumulated up to that period.
