About us


Welcome to CS17 Finance Workshop, part of the CS17 Tools collection of practical and easy-to-use online tools. CS17 Finance Workshop was created to make common financial calculations easier to understand. Whether you are considering a loan, looking at a home mortgage, planning your savings or exploring how compound interest can affect your money over time, our aim is to provide clear calculations without unnecessary complexity.

Financial Calculations Made Simple

Financial calculations can sometimes be difficult to understand, particularly when interest rates, repayment frequencies and long time periods are involved. CS17 Finance Workshop brings several useful financial calculators together in one convenient place. Our Finance Workshop currently includes: Loan Calculator
Estimate weekly, fortnightly or monthly loan repayments, total interest, total repayments and how the loan balance may change over time. Mortgage Calculator
Estimate home-loan repayments based on the property price, deposit, interest rate and loan term. You can also explore how additional repayments may reduce the loan term and total interest. Compound Interest Calculator
See how an initial amount and regular contributions may grow over time using different assumed rates of return and compounding frequencies. Savings Goal Calculator
Set a savings target and estimate how much you may need to save weekly, fortnightly or monthly to reach your goal.

More Than Just the Final Number

We believe a financial calculator is more useful when you can see what is happening behind the result. Where appropriate, Finance Workshop provides additional information such as total interest, total repayments, estimated interest savings, contributions and year-by-year balance information. This allows you to compare different scenarios and better understand how changing an amount, interest rate, repayment or time period may affect the result.

Explore Different Scenarios

Finance Workshop is designed to make it easy to experiment. For example, you can see what may happen if you increase a mortgage repayment, change the term of a loan, contribute more regularly to savings or use a different assumed investment return. These comparisons can help make complicated financial calculations easier to understand.

Designed for Different Devices

CS17 Finance Workshop is designed to work on desktop computers, laptops, tablets and mobile phones. There is no software to install and no account required. Simply choose the calculator you need, enter your figures and calculate your results.

Important Information

CS17 Finance Workshop is a general-purpose financial calculation tool. Results are estimates based on the information you enter and the calculation methods used by the website. Actual loans, mortgages, savings and investments may be affected by factors including fees, taxes, changing interest rates, lender calculation methods, offset accounts, redraw facilities, repayment timing, market performance and other conditions that may not be included in our calculators. Investment returns are not guaranteed, and past or assumed rates of return do not guarantee future results. CS17 Finance Workshop does not provide personal financial, investment, lending, accounting, taxation or legal advice. For important financial decisions, calculations should be independently checked and, where appropriate, advice obtained from a lender, accountant, licensed financial adviser or other suitably qualified professional.
