Frequently Asked Questions
Are these financial calculators accurate?
Our calculators use industry-standard formulas for mortgage payments (standard amortization), compound interest (periodic compounding), retirement projections (geometric growth), and budget allocations (50/30/20 guidelines). They provide solid estimates for planning purposes. For mortgage rates and debt payoff, actual results depend on your specific loan terms and lender.
Do the calculators work for Canada?
Yes. All calculators work for both US and Canadian users with equivalent currencies. The Mortgage Calculator includes a Canadian CMHC mortgage insurance note. The Retirement Planner can be used with RRSP/TFSA contributions. The Debt Payoff calculator works with any loan structure.
Is my financial data saved?
No. All calculations happen entirely in your browser. We do not collect, store, or transmit any of the numbers you enter into our calculators. Your financial information stays private on your device.
What is the 4% rule used in the Retirement Planner?
The 4% rule is a widely cited guideline from the Trinity Study (1994, updated) suggesting retirees can safely withdraw 4% of their portfolio annually (adjusted for inflation) without running out of money over a 30-year retirement, based on historical US stock and bond market performance.
How should I use the Mortgage Calculator?
Use sliders to set your home price, down payment, interest rate, and loan term. Input your estimated monthly property tax and insurance. The calculator shows your estimated PITI payment (Principal, Interest, Tax, Insurance), total interest paid, and a simplified amortization schedule. Canadian users: your actual rate may differ slightly due to semi-annual compounding conventions.
What is a good savings rate?
Financial planners generally recommend saving at least 20% of your take-home pay across all categories (retirement, emergency fund, goals). For accelerated wealth building or early retirement, 30–50%+ is common. The 50/30/20 rule allocates 20% to savings and debt payoff, 50% to needs, and 30% to wants.
How do I use the Compound Interest Calculator effectively?
The most impactful inputs are your monthly contribution and time period — not starting balance. Even a $0 starting amount invested consistently for 30 years at market returns grows to a substantial sum. Use the calculator to find your breakeven point where investment income exceeds contributions — that's the power of compounding at work.
