Quick answer. A convertible note template is a short-term debt instrument that converts into equity at a future qualified financing round. The investor lends money to a startup, accruing interest until conversion. Key terms include the principal amount, interest rate (typically 4–8%), valuation cap, discount rate (typically 15–25%), and maturity date (typically 18–36 months). The template below covers UK convertible loan notes and US convertible promissory notes. Download as PDF, Word or Google Docs.

What is a Convertible Note?

A convertible note is a short-term debt instrument that converts into equity (shares) at a future qualified financing round. It is one of the most widely-used instruments in early-stage startup funding because it lets investors put money in quickly without negotiating a company valuation upfront — the valuation is set later, when the next priced equity round happens.

Convertible notes are sometimes called convertible loan notes in the UK or convertible promissory notes in the US. The structure is the same: the investor lends the company money (principal + interest), and the loan converts into shares on a triggering event — usually a qualified equity round.

For background reading, the UK government's SEIS guidance covers tax-advantaged convertible note investments, and the US SEC guidance on Regulation D exempt offerings covers the standard exemption convertible notes rely on for US startups.

Key Components of a Convertible Note

  • Principal amount - the investment sum
  • Interest rate - annual rate accrued on the debt
  • Maturity date - when the note becomes due
  • Conversion discount - price reduction for early investors
  • Valuation cap - maximum conversion valuation
  • Conversion triggers - events that cause automatic conversion
  • Investor rights - information and governance protections

How Convertible Notes Work

Financial diagram showing convertible note conversion process

The Conversion Process

  1. Initial Investment: Investor loans money to startup under convertible note terms
  2. Interest Accrual: Note accrues interest over time (typically 4-8% annually)
  3. Qualifying Financing: Company raises Series A or qualifying funding round
  4. Automatic Conversion: Note converts to equity shares in the new financing
  5. Price Calculation: Conversion price determined by discount and/or cap

Conversion Price Calculation Example

Scenario: $100,000 convertible note with 20% discount and $5M valuation cap

Series A Price: $2.00 per share ($8M pre-money valuation)

Discounted Price: $2.00 × 80% = $1.60 per share

Capped Price: $5M cap ÷ shares outstanding = $1.25 per share

Conversion Price: Lower of $1.60 or $1.25 = $1.25 per share

Shares Received: $100,000 ÷ $1.25 = 80,000 shares

What's Inside the Convertible Note Template

The template is structured the way a corporate lawyer would structure it for you, with twelve standard clauses organised into four logical groups. Each clause has placeholder text you can edit and standard fallback wording where you need a sensible default.

1. Parties & Principal

  • Company (issuer) details
  • Investor (holder) details
  • Principal amount
  • Interest rate & accrual

2. Conversion Mechanics

  • Qualified financing definition
  • Valuation cap
  • Discount rate
  • Conversion calculation method

3. Maturity & Repayment

  • Maturity date
  • Default valuation conversion
  • Repayment terms
  • Extension provisions

4. Investor Rights & Boilerplate

  • Most-favoured-nation clause
  • Information rights
  • Pro-rata rights
  • Subordination & ranking
  • Governing law

All twelve clauses are editable. The cap, discount and qualified-financing threshold are the three numbers you negotiate with each investor — the rest of the document stays the same across the round.

Convertible Notes vs SAFE vs Equity Comparison

The three most common ways early-stage startups raise capital are convertible notes, SAFEs, and priced equity rounds. Each trades off speed, complexity, and investor protection differently. The chart below shows where each instrument sits across the four most important dimensions.

Funding Instrument Comparison — Speed vs Complexity Higher bar = more of that attribute CONVERTIBLE NOTE SAFE PRICED EQUITY Speed to close Legal cost Complexity Investor protection High Moderate Moderate Strong Highest Low Low Light Slow Highest Highest Highest BEST FOR Bridge funding Pre-seed/Seed (UK) BEST FOR Pre-seed/Seed YC-style rounds (US) BEST FOR Seed and beyond Series A+ rounds
Convertible notes give investors interest accrual and a maturity date (stronger protection); SAFEs are the fastest and cheapest but offer the lightest investor protection; priced equity rounds are the gold standard but slow and expensive.
Feature Convertible Note Equity Round SAFE
Instrument Type Debt that converts to equity Direct equity purchase Future equity agreement
Interest Rate Yes (4-8% typical) No No
Maturity Date Yes (12-24 months typical) No No
Immediate Valuation No Yes No
Legal Complexity Medium High Low
Time to Close 2-4 weeks 2-4 months 1-2 weeks
Board Rights Limited/Information only Yes, full governance Limited/Information only

When to Use Each Instrument

  • Convertible Note: Need bridge financing, established company with track record
  • Equity Round: Ready for full valuation, need significant capital, want investor governance
  • SAFE: Very early stage, want simplest terms, prefer Y Combinator standard

UK vs US Legal Context

Convertible notes work similarly in UK and US law but the terminology, registration and tax treatment differ. Here's the orientation.

United Kingdom (Convertible Loan Notes)

In the UK, the equivalent instrument is usually called a convertible loan note (CLN). The note must be registered in the company's books, and any allotment of shares on conversion requires board authority and a Companies House filing under the Companies Act 2006.

UK convertible loan notes can qualify for Advance Subscription Agreement (ASA)-style tax-advantaged treatment under the Seed Enterprise Investment Scheme (SEIS) or Enterprise Investment Scheme (EIS) — but only if the conversion is structured as an irrevocable equity subscription, not a loan. Standard convertible loan notes do not qualify for SEIS/EIS relief; for that, founders should consider an Advance Subscription Agreement instead.

Under FCA Perimeter Guidance (PERG), convertible notes are typically structured to fall within the financial promotion exemptions under the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 — usually the high-net-worth or sophisticated-investor exemptions.

United States

In the US, the equivalent is a convertible promissory note. These are issued under federal exemptions from registration — almost always SEC Regulation D Rule 506(b) or 506(c), which permit unregistered offerings to accredited investors.

The SEC's accredited investor rules determine who can buy unregistered convertible notes. State-level "blue sky" filings (Form D) are typically required within 15 days of the first sale.

Both jurisdictions

The substance of the instrument is the same: principal + interest + maturity + conversion mechanics. Only the surrounding regulatory framework, terminology, and tax treatment differ. The template handles both jurisdictions cleanly — just set the governing law and adjust the company-formation references.

Common Mistakes to Avoid

Top 12 Convertible Note Pitfalls

  1. Excessive valuation caps: Setting caps too low relative to company progress
  2. Short maturity periods: Insufficient time to achieve conversion milestones
  3. High interest rates: Burdensome rates that hurt cash flow if notes don't convert
  4. Unclear conversion mechanics: Ambiguous language about conversion price calculations
  5. Missing qualified financing definition: Unclear threshold amounts or conditions
  6. Inadequate maturity provisions: No clear plan for notes that reach maturity
  7. Overly generous investor rights: Rights that interfere with operations or future fundraising
  8. Poor legal documentation: Using generic templates without proper customization
  9. Securities law non-compliance: Failing to comply with federal and state securities regulations
  10. Tax implications oversight: Not considering imputed interest or other tax consequences
  11. Multiple note coordination: Inconsistent terms across different investors
  12. Due diligence shortcuts: Inadequate vetting of investors or terms

Convertible Note — Frequently Asked Questions

FAQ and questions about convertible notes

A convertible note is a short-term debt instrument that converts into equity (shares) at a future qualified financing round. It is widely used in early-stage startup funding because it lets investors put money in quickly without negotiating a company valuation upfront. The valuation is set later, when the next priced equity round happens.

A convertible note is a debt instrument that accrues interest and has a maturity date — it must convert or be repaid by then. A SAFE (Simple Agreement for Future Equity) is not debt — it has no interest, no maturity, and only converts on a triggering event. SAFEs are simpler and faster; convertible notes give investors stronger rights (interest accrual, repayment fallback). Most UK investors prefer convertible loan notes; most US Y Combinator-style rounds use SAFEs.

A valuation cap sets a maximum company valuation at which the convertible note converts to equity. If the company raises a priced round at a valuation higher than the cap, the noteholder still converts at the cap — getting more shares than they would at the actual price. Caps protect early investors from being diluted on big subsequent valuation jumps.

The discount rate gives the convertible noteholder a price reduction when converting. Common discount rates are 15 to 25 percent. If the qualified financing prices shares at £1.00 each and the discount is 20%, the noteholder converts at £0.80 per share. The discount compensates the noteholder for the early risk they took.

If the company has not raised a qualifying priced round by the maturity date, the convertible note typically does one of three things: (1) converts at a pre-agreed default valuation, (2) is repaid with accrued interest, or (3) is extended by mutual agreement. The template specifies which of these applies and lets you customise the maturity outcome.

A qualified financing is the priced equity round that triggers automatic conversion of the note. The threshold is set in the agreement — typically a round of at least £500,000 or $1 million in new equity. Smaller rounds may not trigger conversion to avoid the noteholder converting on a small bridge round.

The convertible note template is delivered as PDF, editable Word document and Google Docs. All three formats are included with each download.

Yes. The template is delivered in editable Word and Google Docs formats so you can customise the parties, principal, interest, cap, discount and maturity for each investor. It is common for a startup to issue multiple notes with the same terms across a single fundraising round — just change the investor name and principal for each.

★★★★★

Used this for a bridge round between our seed and Series A. Three angels signed it without legal mark-up. The MFN clause and information rights are exactly the wording I'd seen on a previous deal — saved a meaningful chunk of lawyer fees.

Hannah K. Founder, London Verified buyer · March 2026
★★★★★

As an angel investor who's signed twenty of these, this is the cleanest founder-side convertible note template I've seen. The qualified-financing definition is properly drafted, not the loose wording you see in most online templates.

Marcus T. Angel Investor, Manchester Verified buyer · February 2026
★★★★☆

Decent template. The cap-vs-discount section was genuinely helpful in deciding what to offer. Wish there was a worked numerical example showing the conversion calculation, but the structure is solid.

Cassandra L. Co-founder, Bristol Verified buyer · January 2026
★★★★★

UK-orientated convertible loan note that actually references the Companies Act 2006 properly. Most of what's online is Delaware-style. Used it for a SEIS-adjacent ASA-style structure with my accountant.

Sebastian H. Founder, Edinburgh Verified buyer · March 2026
★★★★★

Issued five identical notes in a single bridge round to different angels. Just changed the name and principal each time. The template handles the qualified-financing trigger uniformly — all notes will convert together.

Naomi P. Co-founder, Cambridge Verified buyer · February 2026
★★★★☆

Saved me time at a critical moment in a bridge round. Closed three angel cheques in a fortnight using this as the base. My corporate lawyer signed off after about thirty minutes of review.
