Free online calculators for money, loans, investing and everyday math
IQlator brings practical calculators and clear explanations into one place. Estimate mortgage and loan payments, compare payoff scenarios, explore investment growth, calculate percentages, convert currencies and units, and use Ask Q when you are not sure which calculator fits your question.
Mortgage & loan calculators
Compare payment, affordability, payoff and interest scenarios using your own assumptions.
1. Choose a calculator or Ask QStart with a specific tool, or describe the calculation you want in everyday language.
2. Review your assumptionsCheck rates, terms, amounts and other inputs. Financial results can change substantially when assumptions change.
3. Compare scenariosTry different rates, payments, terms or contributions to understand how each input affects the result.
Common questions
Are IQlator calculators free?
Yes. The calculators on IQlator are available to use online without a paid subscription.
Are mortgage and loan results exact lender quotes?
No. Calculator results are estimates based on the inputs you provide. Published benchmark rates are shown for context and are not personalized lender offers.
Can I compare different loan or investment scenarios?
Yes. Change the principal, interest rate, term, contribution or other inputs and recalculate to compare alternatives.
What is Ask Q?
Ask Q is IQlator's conversational calculation assistant. It helps identify the type of calculation you need and can guide you toward the relevant calculator.
Graph equations and explore functions
The IQlator graphing calculator helps you visualize how an equation changes across a range of x-values so you can inspect shape, direction and key features.
Enter a function
Type an equation in terms of x and graph it across the visible coordinate plane. Start with familiar examples such as x², 2x + 1, or sin(x) to see how different function families behave.
Compare function behavior
Graphs make it easier to see where values rise or fall, cross an axis, reach a turning point, or repeat. Visual inspection can complement algebraic work and help catch input mistakes.
Use the graph as a learning aid
A graph is an estimate drawn from sampled values. For exact roots, intersections, derivatives or other formal results, verify the answer with the appropriate algebraic or numerical method.
Common functions to try
Linear: y = 2x + 3 • Quadratic: y = x² − 4 • Trigonometric: y = sin(x)
Changing coefficients lets you see how slope, vertical position, width and other characteristics affect the graph.
Graphing calculator FAQ
What does an x-intercept show?
An x-intercept is a point where the graph crosses the x-axis, meaning the function's y-value is zero at that x-value.
What does a y-intercept show?
The y-intercept is the function value when x equals zero, provided the function is defined there.
Why might a graph look different at another zoom level?
The viewing window changes how much of a function you can see. Zooming in can reveal local detail, while zooming out can make broader behavior easier to recognize.
Calculations with context
IQlator helps you choose the right tool, understand the inputs, and explore what-if scenarios.
Ask naturally
Describe what you are trying to calculate in everyday language. IQlator can route you to a relevant calculator and use the information you already provided.
Check the assumptions
Financial calculations depend on rates, terms, taxes and other assumptions. Review the inputs before using a result for an important decision.
Explore scenarios
