Calculators
Each one does a single job, and does it before you finish typing. The mortgage calculator covers the full monthly payment lenders actually collect — principal, interest, tax, insurance and PMI. The loan calculator handles car, personal and student loans, and shows what an extra payment saves you. Compound interest models how a deposit and regular contributions grow at any compounding frequency. The retirement calculator projects your 401(k) and savings to retirement, including your employer's match, and estimates the monthly income it could provide. Percentage covers the three questions people search for most: a percentage of a number, what percent one number is of another, and percentage change.

Why Moolage is built this way
No waiting, no loading
Every calculator is a single file with no frameworks and no tracking scripts slowing it down. It answers before a download would have started. That's not a marketing line — open any page's source and you'll find plain HTML, CSS and JavaScript, nothing else.
Your numbers stay yours
The math runs in your browser. Nothing you type is uploaded, stored, or sent anywhere — there's no server to send it to. You can check a home price or a salary figure here without it ever touching a database.
The real total, not a teaser
Most free calculators show principal and interest and stop. Ours add tax, insurance and PMI, because that's the number that actually leaves your account. A payment estimate that ignores half your real costs isn't a shortcut, it's just wrong.
Moolage is built for anyone comparing numbers before a decision — buying a home, taking out a loan, growing savings, or just checking the math on a discount. Bookmark the ones you use; the whole suite adds new calculators the same way, with no account required to use any of them.
Most comparison sites make you hand over an email address before you see a real number, or bury the answer under three screens of ads. Every calculator here shows its result the moment you land on the page, with the full working shown below it — the tax breakdown on a mortgage payment, the year-by-year growth on a savings balance, the exact formula behind a percentage change. If a number matters enough to look up, it's worth seeing how it was calculated, not just the headline figure.
