What each calculator answers
Each calculator answers one question about money. Pick the one that matches the question you have.
What will each loan payment be? The loan and EMI calculator gives the monthly payment, the total interest over the term and a schedule that shows the balance falling payment by payment.
What will my savings grow to? The compound interest calculator shows how a starting sum and regular deposits grow, or the monthly deposit that reaches a goal by a chosen date.
What margin does this price give? The profit margin and markup calculator turns a cost and a price into margin and markup, or finds the price that gives a target margin.
How much do I need to sell? The break even calculator finds the units and the revenue that cover fixed costs, and the sales needed for a profit target.
What rate covers my income goal? The freelance rate calculator works back from the income, expenses and time off you plan to an hourly and a day rate.
How much tax is in this price? The VAT and GST calculator adds tax to a net price or takes it out of a total, at any rate you type.
What is this amount in another currency? The currency converter uses the daily mid market rate and shows what a provider margin would cost on the conversion.
The results are information, not advice. A lender, an accountant or a tax office can give you a figure that fits your own situation.
