Free financial tools to help you make smarter business decisions. Calculate tax savings, analyze profitability, and optimize your financial strategy.
S-Corp Tax Savings Calculator
Discover how much you could save on self-employment taxes by electing S-Corporation status. Compare your current tax burden with potential S-Corp savings.
Your Tax Comparison
When to Consider S-Corp
Generally beneficial when net profit exceeds $60,000 annually. The sweet spot is typically between $75,000-$250,000 in profit.
Reasonable Salary Rules
The IRS requires a "reasonable" W-2 salary. Industry standards suggest 40-60% of net profit, depending on your role and industry.
Election Deadline
S-Corp election must be filed by March 15th for the current tax year, or within 75 days of forming your business.
Restaurant Prime Cost Calculator
Calculate your restaurant's prime cost—your largest controllable expense. A healthy prime cost is typically 55-60% of sales.
Ideal Prime Cost
A prime cost of 55% or less is considered excellent for most restaurants, indicating strong cost control and profitability.
What's in COGS?
COGS includes all food and beverage inventory costs, including any supplies used for packaging and serving.
What's in Labor?
Total Labor Cost is more than just wages. It should include payroll taxes, benefits, insurance, and bonuses.
Restaurant Labor Cost Calculator
Calculate your labor cost as a percentage of sales to ensure you're staffing efficiently. The industry benchmark is typically 25-35%.
Balancing Act
Labor cost should be balanced with your food cost. If food cost is high (35%), labor should be lower (25%) to maintain a healthy prime cost.
Improve Efficiency
Use POS data to schedule smarter, cross-train staff to handle multiple roles, and invest in tech to automate simple tasks.
Retention is Key
High employee turnover significantly increases labor costs due to recruitment and training. Investing in retention pays off.

Calculate the precise cost of a single menu item by adding up its ingredients. Use this to optimize menu pricing and profitability.
Menu Item Analysis
Strategic Pricing
Aim for an overall menu food cost of 28-35%. Individual items can vary; balance high-cost entrees with high-margin drinks or appetizers.
Account for Waste
Remember to factor in a small percentage for waste (spoilage, mistakes) when calculating your true ingredient costs for maximum accuracy.
Engineer Your Menu
Use this data to identify your most profitable items ("stars") and feature them prominently on your menu to drive sales.
E-Commerce Profit & Margin Calculator
Estimate your net profit and margin per product sold after accounting for all ecommerce costs including marketplace fees, shipping, and advertising.

Hidden Costs
Don't forget returns (3-5%), payment processing (2.9%), and inventory carrying costs in your calculations.
ROAS Target
Your Return on Ad Spend (ROAS) should be at least 3:1 for sustainable growth, meaning $3 in revenue for every $1 spent.

Startup Burn Rate & Runway Calculator
Estimate how long your startup can operate before its funding runs out based on cash on hand and monthly burn rate.

Focus on variable costs, renegotiate contracts, and consider revenue acceleration to extend your runway.
Efficiency Metrics
Track your burn multiple (net burn ÷ net new ARR) - aim for under 1.5x for efficient growth.
Capital Gains Tax Estimator
Calculate your estimated capital gains tax on an investment. This calculator helps you see the difference between short-term and long-term tax rates.
Tax Calculation
Holding Period Matters
Holding an asset for more than one year is the key to qualifying for lower long-term capital gains tax rates (0%, 15%, or 20%).
Primary Residence
You can exclude up to $250k ($500k if married) of gains from the sale of your primary home if you meet ownership and use tests.
Tax-Loss Harvesting
You can sell losing investments to realize a capital loss, which can then be used to offset capital gains and up to $3,000 of ordinary income.
Coffee Shop Break-Even Calculator
Estimate how many cups of coffee you need to sell each month to cover your costs and break even.
Coffee Shop Metrics
The average coffee shop needs 200-300 daily customers. Focus on increasing average ticket size with upsells.

Location Matters
A high-traffic location can justify higher rent if it brings sufficient customer volume to exceed your break-even point.
Payroll Net Pay Estimator
Estimate an employee's net (take-home) pay after federal and state tax withholdings.
FICA Taxes
This estimate doesn't include FICA (Social Security & Medicare). Remember to budget for an additional 7.65% from both employee and employer.
W-4 Matters
Actual withholding is determined by an employee's Form W-4. This calculator provides a general estimate.
401(k) & Deductions
Pre-tax deductions like 401(k) or health insurance will lower the taxable gross pay and can change the final net pay.

Estimate your SaaS company’s value using common revenue and valuation multiples. Useful for fundraising and exit planning.
Multiple Factors
Growth rate, profit margins, customer retention (NRR), and market size all heavily impact valuation multiples.
The Rule of 40
For SaaS companies, your Growth Rate % + Profit Margin % should exceed 40% to achieve premium valuations.
Market Conditions
Valuations fluctuate with market sentiment. 2021 highs vs. 2023 corrections have shown 50%+ swings in public multiples.
AMT ISO Tax Estimator
Estimate the potential Alternative Minimum Tax (AMT) from exercising Incentive Stock Options (ISOs).
AMT Estimate
The AMT Trap
AMT is due for the year you exercise, even if you can't sell the shares yet. This can create a major cash crunch if not planned for.
Early Exercise
Exercising early when the Fair Market Value (FMV) is close to the strike price can significantly minimize or eliminate the AMT impact.
83(b) Election
If you exercise early, file an 83(b) election within 30 days to lock in the tax treatment at the current, lower valuation.
