How to Use Project Budgets
Learn how to plan and track budgets for one-time projects. Perfect for home renovations, vacations, or any project where you need to estimate costs and monitor spending from start to finish.
What is a Project Budget?
A project budget helps you plan and track costs for one-time events or specific projects with a fixed total budget. Unlike monthly budgets that track regular income and expenses, project budgets help you estimate, allocate, and monitor spending for unique projects from start to finish.
Why Use a Project Budget?
- Stay on track – Know exactly how much you can spend and what's left
- Compare estimates to reality – Track what you planned versus what you actually spent
- Avoid overspending – Get alerts when you're approaching your budget limit
- Make better decisions – See variance calculations to help adjust your spending
- See everything in one place – View all project costs organized together
- Plan with confidence – Whether it's a £2,000 trip or a £20,000 wedding, stay in control
Perfect For:
Home Projects
Kitchen renovations, bathroom upgrades, landscaping, painting, new furniture
Travel & Vacations
Holidays, weekend trips, family vacations, honeymoons, backpacking adventures
Life Events

Personal Projects

How to Set Up Your Project Budget
Step 1 Name Your Project & Pick Your Currency
Go to Project Budget from the main menu. Click Create New Budget and provide clear, descriptive project designation facilitating subsequent identification. Include optional contextual description for enhanced project clarity.
Project Nomenclature Examples:
- "Master Bedroom Renovation" – Be specific about which room or area designation
- "Garden Landscaping Enhancement" – Clear, straightforward project description
- "Spain Travel - August 2026" – Include location and timeframe for travel initiatives
- "Wedding Ceremony - June 2027" – Include dates for major events
Then pick your currency symbol (£, $, €, ¥, etc.) and how many decimal places to show. Most currencies utilize 2 decimal places (e.g., £1,250.50), while some employ 0 (e.g., ¥1250). Select currency denomination aligned with expenditure location.
Step 2 Add Your Costs
Now you're ready to build your project budget. Click "Add Item" to start adding costs. For each item, you'll enter:
Description
Cost purpose identification. Provide specificity for subsequent reference.
Examples: "Venue Reservation Deposit", "Return Flights (2 passengers)", "Bathroom Floor Tiling Material", "Digital Marketing Allocation", "Catering - Principal Course"
Estimated Cost
Projected expenditure for this component. Provide optimal estimate based on quotations, research, or historical data.
Tip: Get multiple quotations and utilize higher estimates. Conservative projection prevents budget shortfalls.
Actual Cost
Upon purchase or payment execution, record realized expenditure amount. Leave blank until you actually pay for it.
This lets you compare projections and actuals, identifying over/under budget status.
Statement Function: The list icon () next to each amount opens the Statement capability, enabling itemization of constituent transactions comprising the total. For example, "Catering" allocation of £2,500 can be subdivided (Appetizers: £400, Principal Course: £1,200, Desserts: £600, Beverages: £300) with automatic aggregation.
Step 3 Use Sorting & Editing Tools
Once you've added a few cost items, you'll want to organize and manage them effectively. The project budget includes several powerful tools:
Sort Columns
Click the arrows in the Estimated or Actual column headers to sort your costs by amount. This is useful for prioritizing high-cost items or reviewing spending patterns at a glance.
Edit Mode
Click the list icon button at the top of the table to enter edit mode. You can delete rows you no longer need or drag-and-drop items to reorder them (e.g., group related costs together like all catering items, all venue costs, etc.). Click the button again to exit edit mode.
Pro Tip: Use the Split Costs feature ( icon next to any amount) to divide expenses between multiple people or break down composite costs into itemized sub-lists. Perfect for shared projects or detailed expense tracking!
Step 4 Track Your Budget & Spending
At the bottom of your project budget, you'll see a detailed summary that updates automatically as you add and update costs:
Total Estimated
Sum of all estimated costs across your entire project. This shows what you expect to spend based on your research and quotes.
Total Actual
Sum of all actual costs you've paid so far. Only includes items where you've entered an actual cost (completed purchases).
Remaining Budget
How much money you have left to spend: Total Budget - Total Actual. Watch this number to avoid overspending!
Variance
Difference between estimated and actual costs: Estimated - Actual. Green = under budget, Red = over budget.
Understanding Variance
- Positive Variance (Green): You're spending less than estimated – great news! You have wiggle room.
- Negative Variance (Red): You're spending more than estimated – time to review and adjust other costs.
- Zero Variance: You've hit your estimates perfectly
Step 5 Update Actual Costs as You Spend
As you make payments throughout your project, return to your budget and enter the actual costs. This keeps your budget current and helps you make informed decisions about remaining purchases.
Best Practice: Update your actual costs immediately after making a purchase while you have the receipt. Set a weekly reminder to review your project budget and ensure all costs are current. This prevents surprises and helps you stay in control.
Pro Tips
- Start with estimates: Add all your expected costs first, even if you haven't paid yet. This gives you a clear picture of whether your budget is realistic.
- Update as you go: Fill in the "Actual Cost" column as you pay for things. This keeps your budget accurate and up-to-date.
- Split shared costs: If multiple people are contributing, use the split feature to divide costs fairly (e.g., "Accommodation: £1200 split 3 ways = £400 each").
- Add contingency: Include a "Contingency" or "Buffer" item (e.g., 10% of your total budget) to cover unexpected costs.
- Compare projects: Create multiple project budgets to compare options (e.g., "Wedding Option A" vs "Wedding Option B").

Frequently Asked Questions About Project Budgets
Project budgets are for one-time events or specific projects with a fixed total budget (weddings, holidays, renovations, business projects). You track estimated vs actual costs and see the difference.
Monthly budgets are for ongoing, recurring income and expenses that repeat each month (salary, rent, bills, groceries). You track regular cash flow and monthly savings.
Use project budgets for special events and monthly budgets for everyday finances. You can use both simultaneously!
A good rule of thumb:
- Simple projects (holiday, party): 5-10% contingency
- Medium complexity (wedding, small renovation): 10-15% contingency
- Complex projects (major renovation, business launch): 15-20% contingency
Projects almost always have unexpected costs. A contingency buffer prevents stress and helps you handle surprises without going over your absolute maximum budget.
Yes! Use the split feature to divide costs fairly between multiple people. This is perfect for:
- Shared holiday accommodation with friends
- Group gift purchases
- Business project costs split between departments
- Wedding expenses shared between families
Click the split icon next to any cost item to divide it equally or by custom amounts. Each person can see their share clearly.
When you're overspending in some areas:
- Review which items are over budget and why
- Look for other items where you can reduce spending to compensate
- Use your contingency fund if you included one
- Consider if any remaining items can be cut or downsized
- Decide if you need to increase your total budget (if possible)
The variance calculation shows you exactly where you stand. Red numbers mean you need to take action before continuing with remaining purchases.
Absolutely! Create as many project budgets as you need. Common use cases:
- Compare options – Create "Wedding Venue Option A" and "Wedding Venue Option B" to compare total costs
- Multiple active projects – Manage your kitchen renovation and holiday planning simultaneously
- Year-round planning – Have separate budgets for different events throughout the year
- Business projects – Track multiple client projects or campaigns independently
Each project budget is completely separate with its own total budget, currency settings, and cost items.
