Simple financial tools for everyday planning
Money Growth Calculators is a website offering interactive tools to help people explore personal finance questions. Our calculators cover savings, compound interest, investment growth, net worth, mortgage payments, mortgage affordability and loan repayments.
Each calculator is designed around a practical financial question. You can enter your own figures, compare different assumptions and see how changes to contributions, interest rates, fees, loan terms or time periods affect the estimated results.
Our purpose is to make common financial calculations easier to understand without requiring spreadsheets or manual calculations. We aim to present useful estimates alongside explanations of the formulas, assumptions and limitations that affect the results.
The calculators use the values entered by the visitor and mathematical formulas appropriate to each calculation. Depending on the tool, the results may include estimated monthly payments, total interest, projected savings, investment growth, the effect of fees and inflation, or a comparison between assets and liabilities.
For example, the compound interest calculator estimates how an initial investment and regular monthly contributions could grow over time. The mortgage calculator estimates principal and interest payments and provides an annual amortization schedule. The investment calculator also allows visitors to explore hypothetical scenarios involving investment fees and inflation.
Calculator results depend on the information entered and the assumptions used by each tool. They are estimates rather than guarantees. Actual investment returns, interest rates, lender terms, fees, taxes and inflation may differ from the values used in a calculation.
We encourage visitors to read the explanations provided on each calculator page and to compare more than one scenario before drawing conclusions. Our calculators are intended for general educational and informational purposes and do not replace personalised financial, investment, tax, legal or mortgage advice.
