📊 Budgeting Calculators
Pick a method first, then plug in your numbers. If you've never budgeted before, the 50/30/20 calculator is the friendliest starting point.
50/30/20 Budget Calculator
Splits your take-home pay into 50% needs, 30% wants, and 20% savings and debt payoff. Adjustable percentages if the standard rule doesn't fit.
Daily Spend Limit
Calculates how much is safe to spend each day after fixed bills and savings are taken out. Useful when you want a number to check before a discretionary purchase.
💰 Debt & Loan Tools
Run different payoff strategies side by side and project mortgage and loan costs before signing anything.
Debt Snowball & Avalanche Tracker
Enter your debts and compare the snowball method (smallest balance first) against the avalanche method (highest interest first). Shows total interest paid and payoff date for each.
Loan & Mortgage Calculator
Standard amortization, plus the impact of extra monthly payments, annual lump sums, and one-off prepayments. Includes property tax, insurance and PMI for mortgages.
🎯 Savings & Goal Planners
Pick a target and let the math tell you what monthly contribution gets you there.
Emergency Fund Calculator
Sizes your fund target based on your actual essential expenses, not a generic "3 months." Adjusts for job stability, dependents, and existing safety nets.
Savings Goal Tracker
Pick a goal amount and a deadline; the tool tells you the monthly amount required and projects progress over time.
Compound Interest Calculator
Project growth on a starting balance plus regular contributions. Optional inflation and tax adjustments show "real" returns alongside nominal ones.
Retirement Planner
Estimates the nest egg needed for the retirement you describe (lifestyle level, target age, life expectancy) and a sustainable monthly contribution to get there.

How these tools work
Browser-based
Each calculator is a single web page. Type your numbers in, see the result. Your inputs stay on your device — they're not sent to a server.
No sign-up
You don't need an account, an email address, or a download. The tools work whether you're a first-time visitor or a regular user.
Re-runnable
Numbers change. Run any calculator as often as you like — when income changes, when a debt is paid off, or when you renegotiate a bill.
Not sure where to start?
If this is your first time setting up a budget, read the beginner's guide first, then come back and try the 50/30/20 calculator.
