Most people Google a financial question, land on a cluttered site with pop-ups and a calculator buried under three ad units, and give up. We built the finance section of Launch Arcade so that doesn't happen. Clean tools, no sign-ups, no nonsense — just answers.
Here are the ones worth bookmarking.
Compound Interest Calculator
This is the one that changes how people think about money. Plug in a starting amount, an interest rate, and a time horizon, and watch a modest savings habit turn into something genuinely surprising. It's especially good for comparing scenarios — what if I added $50 more a month? What if I started five years earlier? The results have a way of being motivating rather than depressing, which isn't something you can say about every finance tool.
Try the Compound Interest Calculator
Mortgage Calculator
Not just a payment estimator — this one shows you the full amortization schedule. That means you can see exactly how much of each payment goes to interest versus principal, month by month, for the life of the loan. It's the kind of transparency that makes you want to throw extra money at your mortgage every chance you get. Or at least understand why your early payments feel so unsatisfying.
EMI Calculator
EMI stands for Equated Monthly Installment — the fixed payment you make on a loan each month. This tool is especially handy if you're shopping for a car loan, a personal loan, or anything with a fixed repayment schedule. Change the loan amount, the interest rate, or the tenure, and the numbers update instantly. Good for figuring out the maximum loan amount you can actually afford before you fall in love with something out of your budget.
Budget Maker
Most budgeting tools are either too simple (a basic table) or too complicated (requires linking your bank, setting up categories, surviving onboarding). Budget Maker sits in a genuinely useful middle ground. You get a personal budget dashboard with interactive charts, income and expense tracking, and enough structure to see where your money actually goes. No account required. You can have a working budget set up in under ten minutes.
Loan Calculator
Straightforward and fast. Enter your loan amount, interest rate, and repayment period, and get your monthly payment with a full interest breakdown. The interest breakdown is the part most quick calculators skip — it matters, because knowing total interest paid over the life of a loan has a way of sharpening your decision-making considerably.
Tip Calculator
Look, not every financial decision involves compound interest. Sometimes you just need to split a $94 dinner bill between four people and figure out a 20% tip without doing embarrassing math at the table. This one handles bill amount, service quality tiers, and splits. Small tool, solves a real problem, zero friction.
Piggy Bank
The only tool on this list designed for kids — and honestly one of the most thoughtful ones we carry. Three jars per child: Save, Spend, and Give. Parents can track contributions and help kids build actual money habits rather than just abstract lessons. The five-star rating is well earned. Teaching a kid to think about giving as part of budgeting, not an afterthought, is something most adult finance apps don't even bother with.
