Table of Contents
1. Getting Started: Upload Your Data
Step 1: Prepare Your CSV File
What You Need:
- A CSV file with your P&L actuals
- First column: Line item names (Revenue, COGS, Salaries, etc.)
- Subsequent columns: Monthly actual values
- Column headers: Dates (e.g., "Jan 2024", "Feb 2024", etc.)
Example Format:
Line Item,Jan 2024,Feb 2024,Mar 2024,Apr 2024
Total Revenue,100000,105000,110000,115000
Total COGS,30000,31500,33000,34500
Gross Profit,70000,73500,77000,80500
Salaries,25000,25000,26000,26000
...
Net Income,15000,17000,18500,20000
Supported P&L Structures:
- Standard P&L (Revenue → COGS → OpEx → Net Income)
- With "Gross Margin" instead of "Gross Profit"
- With "Direct Costs" instead of "COGS"
- With "Operational Expenses" or "Operating Expenses"
- With non-operating items (Interest, Taxes, Other Income/Expenses)
Step 2: Upload Your File
- Click the "Upload Actuals (CSV)" button in the left sidebar under "Quick Actions"
- Select your CSV file
- Wait 2-3 seconds for processing
- You'll see your filename appear below the buttons with a checkmark
- Your actual values now populate the tables
Step 3: Run Your First Forecast
Click the "Run Forecasts" button to generate your initial forecast using default settings (5% linear growth, 12 months).
2. Basic Forecast Setup
Located in the left sidebar under "Model Configuration".
Forecast Periods
What it is: How many months to forecast into the future
How to set:
- Input field: "Number of periods to forecast"
- Range: 1-60 months
- Default: 12 months
Example:
- 12 = forecast one year ahead
- 24 = forecast two years ahead
- 36 = forecast three years ahead
Forecast Method
What it is: How each line item grows over time
Your Options:
1. Linear Growth Default
- Adds the same dollar amount each month
- Formula:
Next Month = Current Month + (Current × Monthly Rate) - Best for: Steady, predictable growth (mature businesses)
- Example: $100k → $105k → $110k → $115k (adds $5k each month)
2. Exponential Growth
- Compounds growth month-over-month
- Formula:
Next Month = Current Month × (1 + Monthly Rate) - Best for: High-growth businesses, percentage-based growth
- Example: $100k → $105k → $110.25k → $115.76k (5% compounds)
3. Logarithmic Growth
- Growth rate slows over time (diminishing returns)
- Formula:
Value = Current × (1 + Rate)^log(month) - Best for: Market saturation scenarios, maturing products
- Example: Fast growth early, then plateaus
4. Rolling Average
- Uses average of recent X months
- Formula:
Forecast = Average(Last X Months) - Best for: Volatile/seasonal businesses
- Example: Average of last 3 months = next month's forecast
- Settings:
- Rolling Period: How many months to average (default: 3)
- Apply Growth Trend: Checkbox to add growth on top of average
Annual Growth Rate
What it is: The percentage growth you expect annually
How to set:
- Input field: "Annual growth rate (%)"
- Positive numbers = growth (e.g., 15%)
- Negative numbers = decline (e.g., -5%)
- Zero = flat (no growth)
• For Linear method: Applied as simple monthly addition (rate ÷ 12)
• For Exponential and Logarithmic: Converted to compound monthly rate using
(1 + annual)^(1/12) - 1• For Rolling Average: Only applies if "Apply Growth Trend" is checked
Example:
- 12% annual growth = 1% compound monthly growth (Exponential)
- 12% annual growth = 0.95% monthly addition (Linear)
3. Advanced Forecast Controls
Seasonality
What it is: Monthly patterns where certain months perform better/worse
Located: Model Configuration → "Seasonal Pattern" dropdown
Your Options:
No Seasonality Default
- Steady growth with no monthly variation
- Best for: Subscription businesses, steady services
Quarterly Peaks:
- Q1 Peak (Jan-Mar): Strong January-March (Tax prep, New Year fitness, financial planning)
- Q2 Peak (Apr-Jun): Strong April-June (Real estate, weddings, graduations)
- Q3 Peak (Jul-Sep): Strong July-September (Back-to-school, summer camps)
- Q4 Peak (Oct-Dec): Strong October-December (Holidays, year-end)
Seasonal Peaks:
- Spring Peak (Mar-May): Strong March-May (Landscaping, gardening, spring fashion)
- Summer Peak (Jun-Aug): Strong June-August (Travel, hospitality, outdoor recreation)
- Fall Peak (Sep-Nov): Strong September-November (Halloween, harvest, fall sports)
- Winter Peak (Dec-Feb): Strong December-February (Ski resorts, heating, winter holidays)
Custom Pattern:
- Define your own monthly multipliers
- Set each month individually (0.5 = 50% of baseline, 1.5 = 150% of baseline)
Seasonality Strength Slider (0-100%):
- 0%: No seasonality applied (same as "None")
- 50%: Moderate seasonal variation
- 100%: Full seasonal pattern applied
- Use case: Test different seasonality intensities without changing the pattern
Seasonal Value = Base Forecast × (1 + (Multiplier - 1) × Strength%)
Example:
- Base forecast: $100k
- December multiplier in Q4 Peak: 1.5
- Seasonality strength: 100%
- December forecast: $100k × 1.5 = $150k
Operating Leverage (80% Rule)
What it is: Automatic expense scaling relative to revenue growth
Located: Model Configuration → Checkbox "Apply operating leverage (80% rule)"
How It Works:
- When checked: Expenses grow at 80% of your revenue growth rate
- When unchecked: Expenses grow at the same rate as revenue
Example:
- Revenue growth: 20% annual
- With 80% rule: Expenses grow at 16% annual
- Result: Margins expand as you scale (operating leverage)
When to Use:
- High-growth companies scaling efficiently
- SaaS/software businesses with low variable costs
- Service businesses with fixed cost bases
When NOT to Use:
- Retail with high variable costs (COGS scales linearly)
- Manufacturing with material costs tied to revenue
- When you want granular control per expense
Custom Growth Rates (Per Line Item)
What it is: Override global growth rate for specific line items
How to Set:
- Go to the P&L Forecast tab in the left sidebar
- Scroll down to "Custom Independent Growth Rates" section
- Select a line item from the dropdown
- Enter a custom annual growth rate for that item
- Click "Set Custom Rate"
When to Use:
- Fast-growing product lines (set Revenue Product A to 25% while overall is 10%)
- Declining expenses (set Software Licenses to -5% for cost cutting)
- Flat items (set Rent to 0% for no growth)
- Different cost structures (set COGS to 5% while OpEx uses global 10%)
Example Workflow:
- Global growth rate: 10%
- Marketing expense custom rate: 25% (investing heavily)
- Rent custom rate: 0% (locked in lease)
- Result: Marketing grows faster, rent stays flat, everything else at 10%
• Custom rates ALWAYS use exact rate entered
• Operating leverage (80% rule) does NOT apply to custom rates
• Custom rates apply to both actuals and forecasts
Visual Indicator:
- Items with custom rates are listed in the "Custom Independent Growth Rates" section
- You can see all custom rates and remove them from this section
4. Goal Seek: Work Backwards from Targets
What it is: Calculate the growth rates needed to hit a specific financial target
Located: "Goal Seek" tab (between Yearly Forecast and Sensitivity)
Step 1: Set Your Goal
Target Metric:
- Net Income
- Total Revenue
- Gross Profit
- Operating Income
Current Value:

Target Value ($):
- Enter the dollar amount you want to achieve
- Example: $500,000
Time Period (Months):
- How long to achieve the goal
- Range: 1-60 months
- Example: 24 months (2 years)
Step 2: Choose Your Strategy
Click one of three strategic approaches:
Revenue-Driven
- Philosophy: Grow revenue aggressively
- Approach: Expenses grow at 80% of revenue growth rate (operating leverage)
- Best For: High-growth companies, market expansion, scaling operations
- Example: If revenue grows 40%, expenses grow 32%
Expense-Focused
- Philosophy: Control costs tightly
- Approach: Very low expense growth (50% of revenue growth)
- Best For: Mature companies, profitability improvement, cost optimization
- Example: If revenue grows 20%, expenses grow 10%
Balanced
- Philosophy: Equal focus on revenue and expenses
- Approach: Moderate expense growth (65% of revenue growth)
- Best For: Sustainable growth, stable businesses
- Example: If revenue grows 30%, expenses grow 19.5%

8. Tips & Best Practices
Getting Accurate Forecasts
1. Clean Your Data:
- Ensure CSV is properly formatted
- Remove any non-numeric characters from values (except $ and ,)
- Use consistent date formatting in headers
- Check that totals are actually labeled as totals
2. Choose the Right Forecast Method:
- Mature business, steady growth? → Linear
- High-growth startup? → Exponential
- Entering saturated market? → Logarithmic
- Highly seasonal/volatile? → Rolling Average
3. Use Custom Growth Rates:
- Don't rely solely on global growth rate
- Model specific scenarios per line item
- Example: Marketing up 30%, Rent flat at 0%, Revenue up 15%
4. Test Different Seasonality Patterns:
- Upload your file, run forecast with no seasonality
- Try different patterns (Q2, Summer, etc.)
- See which matches your historical actuals best
- Adjust strength slider to fine-tune
5. Validate with Goal Seek:
- After creating a forecast, use Goal Seek to verify
- "If I grow at this rate, where do I end up?"
- Compare to your expectations
- Adjust forecast settings if needed
Common Mistakes to Avoid
Don't switch methods mid-analysis. Exponential and Linear produce different results. Pick one and stick with it.
If Goal Seek says "Unrealistic", listen to it. Extend timeline or lower target. Don't plan for unachievable growth.
If your expenses don't scale 1:1 with revenue, use the 80% rule. Not using it can make forecasts pessimistic for scaling businesses.
Global growth rate is a starting point, not the answer. Real businesses have line items that grow at different rates. Spend time setting custom rates for key items.
Start with 50% strength, not 100%. Real seasonality is usually moderate. Test against your actuals before committing.

Glossary
CAGR (Compound Annual Growth Rate): Growth rate that accounts for compounding over multiple periods
Operating Leverage: The concept that expenses grow slower than revenue as a business scales
Net Income: Bottom line profit after all revenues and expenses (including non-operating items)
Non-Operating Items: Line items after Operating Income (Interest, Taxes, Other Income/Expenses)
Seasonality: Predictable monthly variations in business performance
Growth Rate (Annual vs Monthly):
- Annual: Year-over-year percentage change
- Monthly: Month-over-month percentage change
- Conversion: Monthly = (1 + Annual)^(1/12) - 1
Forecast Period: Number of months to project into the future
Actuals: Historical financial data from your business
Mixed Period: A quarter or year that contains both actual and forecasted months
Need Help?
Common questions:
- "My Net Income shows $0" → Check that you have Operating Income or Gross Profit + Operating Expenses totals
- "Seasonality isn't showing" → Make sure seasonality strength > 0%
- "Custom growth rate not working" → Go to P&L tab, scroll to Custom Growth Rates section, set rate there
- "Goal Seek says unrealistic" → Extend timeline or lower target based on Reality Check

9. Account & Browser Behavior
Important: Single Account Per Browser
Telescope (like most web applications) supports one logged-in account per browser at a time. If you need to switch between multiple accounts:
- Option 1: Sign out of the current account before signing into another
- Option 2: Use different browsers for different accounts (e.g., Chrome for Account A, Firefox for Account B)
- Option 3: Use incognito/private browsing mode for a second account
Why this happens: This is standard behavior for session-based authentication (used by Gmail, Twitter, Facebook, etc.). The browser stores your login session, and having multiple sessions causes conflicts. This is not a bug — it's how web authentication works!
