You can choose from a quick-view savings calculator that pulls interest rates from various Canadian banks or fintechs, or you can use our more advanced compound interest calculator to see how other factors like inflation and taxes can impact your overall savings growth.
This comprehensive savings calculator is your ultimate tool for calculating savings growth. You can not only see what your savings could be based on a rate you enter manually, but also based on real, current savings interest rates from savings accounts offered by banks and other financial institutions across Canada.

How do factors like inflation and taxes impact savings growth?
Unfortunately, saving for the future is not as straightforward as it may seem. Due to inflation, one dollar now will have less purchasing power in the future than it does now. And unless you’re saving in a tax-exempt account, like a TFSA, you’ll also have to pay taxes on your savings growth.
That means the total savings you can actually use will look different from what a straightforward calculation may make it appear.
To give you an idea of what a more realistic view of your savings will be by taking into account factors like inflation and tax obligations, you can use the calculator below to get a more realistic picture of your potential savings.

How to calculate compound interest
The formula to calculate compound interest is:
A – the future value of your money, including earned interest
P — the initial deposit amount or principal investment
r — the annual interest rate (as a decimal)
n — how often interest compounds each year
t — the number of years the money is invested
For most savings accounts, your interest is compounded daily, or approximately 365 times per year. For long-term savings products like Guaranteed Investment Certificates (GICs), the formula or compounding period might differ.
How to calculate compound interest on bank savings accounts
The compound interest formula is much simpler if you know your bank savings account balance at the end of the business day. Here’s how most banks calculate compound interest on savings account balances:
With most bank savings accounts, interest begins accumulating when you make a deposit and is calculated on your daily closing balance. Typically, your account will be credited at the end of the month (12 times per year). Earnings can be used or spent the same day.
If you close your account, any accumulated interest is deposited the day it’s closed.
Say you deposit $5,000 into a savings account that pays 1.5% interest. For simplicity, we’ll assume there are no bank fees, and you don’t make any subsequent deposits or withdrawals.

Compound interest vs simple interest
Often used to bank savings calculations, compound interest is paid on your initial deposit plus any interest earned. The amount you invest in a savings account earns interest, which is rolled into the total investment. The total investment continues earning interest—only this time, on a bigger balance than before.
Often used for loans, simple interest is only calculated on the original loan amount (the principle). Interest is not part of the calculation.
In Canada, you might earn anywhere from 0.5% to 4% interest on a savings account (sometimes more with a new bank account promotion). So, if you deposit $500,000, you could earn around $2,500–$20,400 in one year. However, this doesn't factor in bank fees, any additional deposits or withdrawals you make or any taxes charged on your interest earnings.
To calculate 5% simple interest on $1,000, multiply 0.05 by 1,000. The answer is $50. To calculate 5% compound interest on $1,000, you need to know how often interest compounds on your money. For example, if interest compounds daily, 5% interest on $1,000 is $51.27. But if interest compounds monthly, 5% interest on $1,000 is $51.16.
Most savings accounts in Canada pay compound interest, but not all do. Speak with a representative from your bank or read the terms and conditions of your account to find out what types of interest is paid on your balance.
