Money is a tool. The decisions we make with it help us build the life we want.
These are the companion calculators to the guide Money Is a Tool. They will not tell you what to do. They exist to help you see your options clearly — the payment, the cost, the timeline, the tradeoff — so that you can make each decision yourself, with confidence.

About Money Is a Tool
Money Is a Tool is a household financial decision guide. These calculators are its companion. Together they have one purpose: to help you see a decision clearly before you make it.
The idea behind it
Most money advice starts by telling you what to do. This does not. It starts from the belief that a household decides better when it can see the whole picture — the payment, the total cost, the timeline, and what the choice asks of the life you are trying to build.
“Here is the information. Here are the consequences. Here are the tools. Now ask yourself: does this decision support the life you are trying to build?”
That question is the method. The guide supplies the information and the consequences. These calculators supply the tools. The decision stays yours, which is where it belongs.
What you will find here
- Four decision tools, free for everyone. A household budget with a pay-period check-in, a borrowing and payment calculator, a savings and goal calculator, and an income and tax planner.
- The guide itself. The complete digital edition, licensed to the reader and available to re-download at any time.
- A classroom edition. Schools can license the book for their teachers together with a full set of materials: the classroom PowerPoint, the Teacher Guide, the Flexible Implementation Guide, and the test and question bank.
How your information is treated
The calculators need no account and collect nothing. Every figure you enter is calculated on your own device and saved only in this browser, so it never reaches us or anyone else. Clearing your browser data clears it for good.
Buying the book does create an account, because a purchase has to be remembered. That account holds your email address and what you bought, nothing more.
Built to be returned to
These tools are not a one-time exercise. A new job, a new goal, a rate that changes, a payment about to become part of your life — each is a reason to open them again. Once a page has loaded it keeps working without an internet connection, and on most phones you can add it to your home screen and use it like an app.
Getting in touch
Schools and school boards can request a licence and ask questions here. Readers who have bought the book can reach their downloads any time by signing in with their email.

My Monthly Household Budget
A budget is not about restricting your life. It is about understanding where your money is going and making sure your financial decisions support the life you want to build.

A budget helps us see what money is coming in, what needs to go out, what we want to save, and whether our choices still support our goals.
How will this help us?
Enter the amount, choose how often it happens, and enter how many times it will happen this month. The budget calculates This Month automatically. Example: paid $3,000 biweekly with 2 pays this month → Amount $3,000, Biweekly, 2 times = $6,000. For flexible spending such as groceries, choose Monthly Budget and enter the whole month’s amount.
When should we return to it?
Review your budget at the beginning of every month and whenever something changes. Use the Pay Period Check-In every payday so you know what must be covered before the next pay.
This month at a glance
My Monthly Review
A few questions to sit with once the numbers are in front of you.
- What changed this month?
- Did I receive the income I expected?
- Did any expense happen more or less often than I expected?
- Am I still saving toward the goals that matter most to me?
- If I have money left, what do I want it to help me achieve?
- If I have a shortfall, what can I change before using more credit?
Pay Period Check-In
Complete this every payday. Look at your due dates on the Monthly Budget and decide what needs to be covered before your next pay.

My Borrowing & Payment Calculator
Understand the payment. Understand the cost. Then decide whether it fits your life.

Why are we completing this?
Being approved tells you what a lender is willing to lend you. It does not tell you what you should borrow. This calculator helps you see what the debt may cost before you commit to it.
How will this help us?
Estimate a payment, see total interest and total repayment, compare two offers on the same basis, and test whether the payment fits the money you currently have available in your household budget.
When should we return to it?
Before financing a vehicle, taking a personal loan or line of credit, comparing lending offers, or adding any new payment to your household.
How to read an interest rate
A percentage alone is not enough to compare two loans. Ask what the quoted annual rate is, how often interest is compounded, whether fees apply, and how long you will be paying. The calculator converts the quoted rate and compounding into an effective annual rate so offers can be compared more fairly.

Does this payment fit my life?
Being approved tells me what a lender is willing to lend. I still decide what belongs in the life I want to build.
IMPORTANT — This is an educational planning tool. Actual lender calculations may use different day-count rules, compounding conventions, fees, insurance, taxes, prepayment rules, promotional terms, or disclosure calculations. Always compare the lender’s written disclosure and ask questions before signing.
My Savings & Goal Calculator
Turn a financial goal into a number you can plan for.
Change the light input cells. The results update automatically.

Why are we completing this?
Knowing that we want to save is a good beginning. Knowing how much we need to save, how long we have, and what our money may grow to gives the goal a plan.
How will this help us?
Use the calculator in two ways. First, see what your current savings plan may grow to. Second, start with a target amount and calculate approximately how much you need to save to reach it.
When should we return to it?
Whenever you set a new goal, change the amount you can save, receive a raise, change your timeline, or want to see how starting earlier or later may affect the result.
About compound growth
Compound growth means your money can earn a return, and over time you may also earn a return on the growth already added. The longer the money remains invested, the more time compounding has to work. The return you enter is an assumption, not a guarantee.

Your savings target
A calculator gives me information. I still decide whether the goal, timeline, and commitment fit the life I want to build.
IMPORTANT — This calculator is an educational planning tool. Actual investment returns can be higher or lower and may be negative. Taxes, fees, inflation, contribution limits, and account rules are not included unless you account for them separately.

Taxes affect the money available to our household throughout the year. Planning ahead can help us understand our income, deductions, withholding, and possible tax responsibility before filing season.
How will this help us?
Combine income from more than one job, add self-employment income, test an RRSP deduction, compare tax withheld with a simplified estimate, and plan how much of side income you may want to reserve.
When should we return to it?
When you start or change a job, add a second job, earn self-employment or side income, consider an RRSP contribution, receive a raise, or want to check whether your current withholding still makes sense.
Check the tax year
Brackets, rates, personal amounts, CPP and EI figures change from year to year. This calculator does not update them automatically — open Tax year & rate information below and enter current CRA figures before using it for a different year.

Tax year & rate information
Tax rules change from year to year and this calculator does not update these numbers automatically. Before using it for a different tax year or province, find the current figures on the CRA pages linked below and update them here. Changing only the percentages may not be enough — thresholds, personal amounts, CPP and EI limits can also change. The Ontario health premium schedule and tax-reduction structure are built in and assume Ontario.

Taxes are easier to manage when I think about them throughout the year, not only when it is time to file my return.
IMPORTANT — This prototype is a simplified educational estimator for Ontario in 2026. It is not a tax return and it does not calculate every deduction, credit, benefit, surtax rule, family situation, business rule, or special tax provision. The final result should always be checked using current CRA information, certified tax software, or a qualified tax professional when appropriate.
