It's often said "a picture is worth a thousand words". If that approximates the truth, here's hundreds of thousands of words worth of finance – and all other sorts of – calculators.
Meet DQYDJ's Calculator Collection
On this page you'll find a vast collection of investment calculators, economics calculators, health calculators, and finance calculators we've created over the past decade.
Better understand complex topics by providing your own inputs to comparisons and visualizations. See net worth, income, investment returns, and all sorts of basic finance calculators. If you're in the mood, you can even estimate your relationship length and compare your body measurements to Americans as a whole.
We hope you enjoy using these interactive tools as much as we enjoyed making them. Oh – and we take requests. Get in touch.
Economics Calculators
It's surprisingly hard to find economic data in a decent resolution for topics such as income and net worth. In this section we've included all our tools on the subject – tools which often allow you to compare versus a measure's distribution in the United States.
Income Calculators
Income is our most popular topic - people love to compare salaries and see the top 1% in the country by various breakdowns. These calculators let you explore the United States income distribution or size up job offers and area demographics.
Net Worth Calculators
Income is what you earn, but net worth is what you've kept. The net worth calculators break down net worth with and without a house, and also dig into other specific forms of wealth.
Econ Simulation and Other Calculators
These calculators show demographics, simulate economic models, model taxes, or compute inflationary changes.
Investment Calculators
Our major issue with financial media is the failure to consider dividend reinvestment when quoting index price returns. Another minor nit? Inflation adjustment – you'll find both features on most of our investment calculators. Along with automatic updates, and (sometimes) periodic investment and even tax and fee estimates.
As for what we've built, we've got you covered - included are DRIP calculators for individual stocks, S&P 500 returns, Dow Jones returns, Bitcoin returns, corporate bond returns (of various grades), and all manner of other commodity and index return calculators.
Commodity and Index Return Calculators
Home price and index return calculators, usually with inflation adjustment and dividend or coupon reinvestment.
Individual Stock and Company Valuation Calculators
Calculators for individual stock returns and dividends or cash flow valuation.
Valuation Theory and Basic Finance Calculators
Basic and market valuation calculators, as well as market inflation expectations.
Other Investment Calculators
Historical simulations, periodic re-investment tools, and other investment calculators that just didn't fit somewhere else.
Personal Finance Calculators
Economics and investment calculators are useful to see the distribution of resources and model past results. Personal finance calculators, on the other hand, help you examine your own situation.
Health Calculators
While many things are replaceable, you only get one body in this life. These health calculators help you compare your physical health as well as see the distribution for the United States.
BMI Calculators
BMI, or Body Mass Index, is a ratio between height and weight that roughly can sort people into healthy or unhealthy body status.
Body Fat Percentage Calculators
Body fat percentage is a superior method to BMI which estimates health status by isolating the amount of body fat a person carries on their body.
Height and Weight Calculators
Height and weight are – well, the single dimension of height and weight for a human. Enjoy!
Math Calculators
Math was the number one reason for computerized calculators – probably followed by calculators for military purposes. These calculators give you quick answers to common math and geometric questions.
Greatest Common Factor Calculator
Natural Logarithm (Log 10) Calculator
Conversion Calculators
Sometimes you just need to convert from one thing to another. These calculators will take the pain out of all of your number and unit conversion.
Random Calculators
Some calculators don't fit in the other sections! Here are some fun calculators for things like relationship length or date calculations that you'll love to share.
An Extensive – and Growing – Online Calculator Collection
We've made quite a few calculators and interactive tools in our time on DQYDJ. We're nowhere near finished with this collection, though. Hopefully over time this page will become even more unwieldy: finance calculators for days!
We're also serious about taking calculator requests. It's all just a little bit of JavaScript and some Python, PHP, R or Excel to prepare the data – the true creativity comes in dreaming up the next interactive tool to create.
Help us out by sending us your ideas. Either way, we hope you enjoyed the tools and calculators!
