Set Your Savings Rate Target
FIRE typically requires a 50%+ savings rate. The higher your rate, the faster you reach financial independence. Most FIRE seekers target 50-70%.
Calculate What's Left
After your savings target and fixed expenses, the remainder is your flexible spending money for the month.
Divide by Days
Your monthly flexible spending divided by days in the month gives you a simple daily limit. Stay under it, and you automatically hit your savings rate.
Track Daily, Hit Your Rate
Instead of checking your savings rate at month-end, you get real-time feedback. Every day you stay under your limit, you're on track for FIRE.
Why Daily Budgets Accelerate FIRE
Instant Feedback
Monthly budgets tell you that you overspent after it's too late. Daily budgets tell you before each purchase whether you're on track.
Savings Rate Built In
Your daily limit already accounts for your savings target. No separate tracking needed — if you stay under, you're automatically saving at your target rate.
Small Numbers, Big Impact
$44/day feels more real than $1,334/month. Small daily limits create a natural pause before purchases and make the math simple.
Self-Correcting
Overspend today? Tomorrow's limit adjusts. Underspend? You have more flexibility tomorrow. The system keeps you on track automatically.
Frequently Asked Questions
What savings rate do I need for FIRE?
It depends on how soon you want to reach financial independence. At a 50% savings rate, you can retire in roughly 17 years. At 70%, it's closer to 8-9 years. Most FIRE seekers aim for 50-70%, though any savings rate above 20% puts you ahead of most people.
Why does the first $100K take the longest?
Compound growth is exponential. When your portfolio is small, investment returns don't add much in absolute terms. But once you hit $100K, those same percentage returns generate meaningful dollar amounts. The second $100K comes faster than the first, the third faster than the second, and so on.
Should I include taxes in my income?
Use your after-tax (net) income — what actually hits your bank account. This gives you an accurate daily spending limit. Pre-tax numbers would overstate what you have available to spend.
What counts as a fixed expense?
Fixed expenses are recurring costs that stay roughly the same each month: rent/mortgage, utilities, insurance, car payment, minimum debt payments, subscriptions. These come out before calculating your daily spending limit. Variable expenses like groceries, dining, and entertainment come from your daily budget.
How do I handle irregular expenses?
For annual expenses (car insurance, holiday gifts), divide by 12 and add to your monthly fixed expenses. This smooths out lumpy spending and gives you a more realistic daily budget. BUDGT can also carry unused budget forward to help with bigger purchases.
