What Are Venture Capital Calculators?

Venture capital calculators help VCs, founders, CFOs, and startup finance teams model valuations, dilution, runway, fund economics, and cap table scenarios. Whether you're raising a funding round, managing a VC portfolio, or planning startup finances, these tools calculate ownership stakes, funding needs, and investment returns. Venture capital teams use these calculators to calculate pre-money and post-money valuations, model dilution from funding rounds and option pools, project startup runway and burn rates, evaluate convertible note and SAFE conversions, calculate VC fund returns and carry, model portfolio construction and diversification, analyze option pool sizing and vesting, project cap table scenarios across multiple rounds, calculate burn multiples and capital efficiency, and evaluate exit scenarios and return distributions. Our suite includes 10 specialized calculators covering essential VC metrics from startup valuation to fund performance.

Common Use Cases

Calculating Startup Valuations

Model pre-money and post-money valuations for funding rounds. Calculate investor ownership percentages, price per share, and valuation impact of different investment amounts. Compare valuation methodologies, benchmark against comparable companies, and model multiple scenarios. Understand how valuation affects dilution and ownership distribution across founders, employees, and investors.

Modeling Dilution Scenarios

Calculate dilution from funding rounds, option pools, convertible notes, and SAFEs. Track ownership percentages across multiple financing rounds and security types. Model option pool creation timing (pre-money vs post-money), SAFE and convertible note conversions with discounts and caps, and cumulative dilution effects. Plan equity retention strategies and anti-dilution provisions.

Projecting Startup Runway

Calculate runway based on current cash, burn rate, and revenue projections. Model different scenarios including revenue growth, burn rate changes, and fundraising timing. Determine optimal time to start fundraising based on target runway at raise. Plan headcount growth, marketing spend, and other investments while maintaining adequate runway buffer.

Sizing Employee Option Pools

Calculate appropriate option pool sizes based on hiring plans, equity budgets, and competitive benchmarks. Model pool creation timing and dilution impact on founders vs investors. Plan equity grants by role, level, and hire sequence. Calculate pool refresh needs and dilution from future hiring. Optimize pool sizing to attract talent while minimizing dilution.

Calculating VC Fund Returns

Model fund-level returns including MOIC (multiple of invested capital) and IRR (internal rate of return) across portfolio companies. Calculate management fees, carry hurdles, and GP/LP distributions. Model different portfolio construction strategies, exit timing scenarios, and power law return distributions. Evaluate fund performance against benchmarks and target returns.

Modeling Portfolio Construction

Plan VC fund deployment including check sizes, number of investments, follow-on reserves, and ownership targets. Model investment pace, reserve strategy (50-70% for follow-ons), and portfolio diversification. Calculate expected returns under different scenarios. Balance portfolio concentration in winners with diversification across sectors, stages, and vintages.


Frequently Asked Questions

How do I calculate pre-money and post-money valuation?

Pre-money valuation is the company value before investment. Post-money valuation equals pre-money valuation plus investment amount. For example, a $10M pre-money valuation with $2M investment results in $12M post-money valuation. Investor ownership percentage is calculated as investment divided by post-money valuation. Our valuation calculators model different scenarios and cap table impacts.

How do I calculate dilution from a funding round?

Dilution is calculated by dividing new shares issued by total shares after the round. If a company has 1M shares and issues 200K new shares, dilution is 200K / 1.2M = 16.7%. Existing shareholders own 16.7% less of the company. Factor in option pools, convertible notes, and SAFEs. Our Dilution Calculator models multiple rounds and different security types.

How do I calculate startup runway?

Runway is calculated by dividing current cash balance by monthly burn rate. A startup with $1M cash and $100K monthly burn has 10 months of runway. Factor in expected revenue growth, changing burn rates, and planned expenses. Model different scenarios including best case, base case, and worst case. Our Runway Calculator helps plan fundraising timing.

What is a typical option pool size?

Option pools typically range from 10-20% of post-money capitalization, with 15% being common for Series A. Earlier stages may have smaller pools (10-12%), while high-growth companies hiring aggressively may reserve 15-20%. Option pools are usually created from pre-money valuation, diluting founders before the new investment. Calculate pool size based on hiring plans and equity budgets.

How do I calculate VC fund returns?

VC fund returns are measured by multiple of invested capital (MOIC) and internal rate of return (IRR). MOIC is total value returned divided by capital invested. IRR accounts for timing of cash flows. A 3x MOIC over 5 years equals approximately 25% IRR. Factor in management fees, carry calculations, and portfolio construction. Model different exit scenarios and timing.

How do convertible notes and SAFEs affect dilution?

Convertible notes and SAFEs convert to equity at the next priced round, typically with a discount (15-20%) or valuation cap. Calculate conversion price, shares issued, and resulting dilution. SAFEs with valuation caps can result in significant dilution if the cap is much lower than the priced round valuation. Model conversion scenarios to understand cap table impact.

What is a good burn multiple for startups?

Burn multiple is net burn divided by net new ARR. A burn multiple under 1.5x is considered efficient, under 1x is exceptional. It measures capital efficiency of growth. Calculate by dividing quarterly net burn by net new ARR that quarter. Optimize by increasing revenue growth rates while controlling burn. Track over time to measure improving efficiency.

How do I model portfolio construction for a VC fund?

Portfolio construction models investment pace, check sizes, reserve ratios, and expected ownership targets. Calculate number of investments based on fund size, average check size, and reserve strategy (typically 50% reserves for follow-ons). Model expected returns using power law distributions where top performers drive fund returns. Balance portfolio diversification with concentration in winners.
