Compound Interest Calculator (aka FIRE Calculator) is a free compound interest calculator and retirement planning tool for people chasing Financial Independence, Retire Early (FIRE). Whether you are aiming for Lean FIRE, Coast FIRE, Barista FIRE, or Fat FIRE, use it to project your nest egg, model savings rate and contributions, and see how compounding can grow your portfolio over time. Compound interest is interest earned on interest. When investment returns are reinvested, each period earns on your principal plus previously accumulated gains. That compounding snowball is the engine behind long-term investing, passive income goals, and building enough invested assets to cover living expenses in early retirement. Plan short-term savings and multi-decade FIRE timelines in one place. Set starting principal, expected annual return, contribution or withdrawal amount, contribution frequency, compounding frequency, and time horizon. Switch between contribution mode for accumulation and withdrawal mode for drawdown planning, including scenarios inspired by safe withdrawal rate thinking and the 4% rule. Review projected balances, charts, and year-by-year tables so you can stress-test your FI number before you leave full-time work. Features included: - Calculate future value with the compound interest formula - Contribution and withdrawal modes for growth and retirement drawdown - Contribution frequencies including monthly, quarterly, semiannually, and daily - Smart Insight tips based on your calculation - Graph and table views under your results - Formulas included for reference - Save, reorder, and share calculations with friends or your FIRE community - Dark Mode and Light Mode

34 days. Not one more. You live in Belgium, France or Germany and work in Luxembourg? You can work up to 34 days a year outside Luxembourg, home working included, without your taxation changing. Go over, and it is not just the extra days that become taxable in your country of residence: it is all of them. Telework Tracker helps you stay under that limit, with peace of mind. YOUR COUNTRY'S RULES Pick your country of residence: the app applies its rules and explains them on every screen. Starting a job in France mid-year? Your limit is adjusted. Living in Germany? A day only counts from 30 minutes of work outside Luxembourg. Living in Belgium? The app also warns you based on the Belgian tax authority's reading. LOG A DAY IN TWO SECONDS One tap each morning: telework, business trip, sick leave or paid leave. Half days too, and the app reminds you they count as a full day. Worked on a Saturday or a public holiday? Log it, and the app counts it once you confirm. ALWAYS KNOW WHERE YOU STAND The annual ring shows the days you have used against your limit. We warn you at 75%, then at 90%. With Pro, you choose those thresholds yourself. YOUR WHOLE YEAR AT A GLANCE Every logged day is marked on the calendar. If your log and your actual office presence don't match, the app flags it so you can check. It never changes anything for you. PRO: AUTOMATION AND PROOF • Your office presence logged automatically by geofencing, on your device, with no manual input • Reconciliation between detected presence and your log • Your own alert thresholds • Multi-year history • A PDF compliance report, with your daily notes and a signature line for your employer PRIVACY FIRST Location is processed on your device: no GPS trails, no ads, no tracking. Your data syncs to EU-hosted servers only if you create an account. In guest mode, everything stays on your iPhone. Telework Tracker is a record-keeping tool, not tax advice. Verify your personal situation with your employer or a tax adviser. SUBSCRIPTION Telework Tracker Pro is an annual auto-renewable subscription, with a 1-month free trial for new subscribers.
