Savings Goal Calculator Canada
This savings goal calculator finds the monthly amount you need to save to reach a target by a chosen date, including the interest you earn.

What it does
The savings goal calculator works out the fixed monthly amount you need to save to reach a target by a chosen date, allowing for money already saved and interest earned.
Data sources & parameters
This calculator uses standard financial formulas and runs entirely in your browser. It needs no external rate data — your result is computed only from the values you enter above.
We always strive to use the latest data for every variable so our results and reports are as accurate as possible. Even so, errors are possible — you should not rely on this tool or its report alone, and we accept no liability for any decision made based on it.
The formula
Monthly = remaining x i / ((1+i)^n - 1), where i is the monthly rate and n the months
How it works
It grows any current savings at the assumed rate, subtracts that from your goal, and solves the annuity formula for the monthly contribution that fills the gap over the months remaining.
Where it is used
- Setting a monthly savings target for a goal
- Planning a house deposit or big purchase
- Seeing how interest reduces the amount you must save
Worked example
To reach CA$20,000.00 in five years at 4%, you would save about … a month, contributing … and earning … in interest.
What the savings goal calculator does
Most saving starts with a target: a house deposit, a car, a wedding, an emergency fund or a trip. Tell the calculator how much you want, by when, what you have already saved and the rate you expect to earn, and it returns the fixed monthly amount that gets you there. It accounts for interest rather than simply dividing the goal by the number of months.
How the calculation works
- Your existing savings grow at the assumed rate for the whole period, and that future value counts toward the goal.
- The remaining gap is what the goal exceeds that grown balance.
- The monthly contribution is the amount that, deposited every month and compounded, fills the gap exactly by the target date.
At a zero rate the answer is the gap divided by the number of months. Otherwise the calculator solves the future value of a series of monthly deposits so that deposits plus growth land on the goal.
A worked example
To reach $20,000 in five years from nothing at 4%, you need about $301.66 a month, not the $333.33 that dividing by sixty months suggests. You contribute about $18,100 and interest supplies about $1,900, which the tool reports separately.
Start with $5,000 already saved and the monthly amount falls to about $209.58. Give yourself ten years instead of five, starting from nothing, and it falls to about $135.82, with interest supplying about $3,701.
Why the rate and horizon matter
A higher rate means more of the goal comes from growth. A longer horizon spreads contributions over more months and gives compounding more time, which is why starting early helps so much. An ambitious goal on a short timeline leaves little room for interest, so nearly all of it must come from contributions, which may prompt a rethink of the target or the deadline.
Where you keep the money matters
Interest in a non-registered account is taxed each year, so enter an after-tax rate there. Inside a TFSA the savings grow without that drag, so the full rate applies. For a first home, the First Home Savings Account combines deductible contributions with tax-free growth, which can make a deposit goal noticeably easier to reach than in a taxable account.
When to use it
- Turning a target into a monthly savings habit.
- Checking whether a house deposit timeline is realistic.
- Testing how a higher rate or longer horizon changes the monthly amount.
- Seeing how much interest contributes to the goal.
Common mistakes to avoid
- Dividing the goal by the months and ignoring interest, which overstates what you need.
- Assuming an optimistic rate you may not earn, which understates it.
- Forgetting tax on interest in a non-registered account.
Reading the result sensibly
The figure assumes steady monthly contributions, monthly compounding and a rate that holds for the whole period. Rates change and life interrupts saving, so round the monthly amount up slightly as a buffer, rerun it when your balance, income or deadline changes, and automate the contribution into the account you have chosen.
