A
ACV (Annual Contract Value)
The annualized revenue value of a single customer contract, excluding one-time fees. ACV is used in enterprise SaaS to measure deal size and compare sales performance.
DefinitionARPU (Average Revenue Per User)
The average monthly or annual revenue generated per user or account. ARPU helps you understand pricing efficiency and segment customers by value.
DefinitionARR (Annual Recurring Revenue)
The annualized value of your recurring subscription revenue. ARR normalizes monthly fluctuations and is the standard metric investors use to benchmark SaaS companies.
Calculator
B
B2B SaaS
A software delivery model where companies sell cloud-based applications to other businesses via subscription. B2B SaaS combines recurring revenue, high gross margins, and scalable distribution.
ArticleBank Loans for SaaS
Traditional debt financing from banks, structured for recurring-revenue businesses. Bank loans typically offer lower interest rates than venture debt but require collateral, profitability history, or personal guarantees.
GuideBootstrapping
Building and growing a business using personal funds and revenue rather than external investment. Bootstrapped founders retain full ownership but must grow within the constraints of their cash flow.
ArticleBreak-Even Point
The point where total revenue equals total costs and the business becomes self-sustaining. For SaaS, this often refers to the month when cumulative revenue covers all prior investment in the product.
CalculatorBridge Financing
Short-term funding used to bridge the gap between two financing rounds or before a major milestone. Bridge financing provides immediate capital while you prepare for a larger raise.
DefinitionBurn Multiple
The ratio of net burn to net new ARR. A burn multiple below 1x means you spend less than a dollar for every dollar of new ARR — a sign of capital-efficient growth.
CalculatorBurn Rate
The rate at which your company spends cash beyond what it earns. Net burn rate equals total expenses minus total revenue, and determines how long your cash runway lasts.
Calculator
C
CAC (Customer Acquisition Cost)
The total cost of acquiring a new customer, including sales and marketing spend. CAC is calculated by dividing total acquisition spend by the number of new customers gained.
CalculatorCAC Payback Period
The number of months it takes to recoup the cost of acquiring a customer through their gross margin contribution. Shorter payback periods indicate more efficient customer acquisition.
CalculatorCash Runway
The number of months your company can continue operating at its current burn rate before running out of cash. Runway is calculated by dividing cash balance by monthly net burn.
CalculatorChurn Rate
The percentage of customers or revenue lost over a given period. Customer churn measures lost accounts while revenue churn captures the dollar impact of downgrades and cancellations.
CalculatorCOGS (Cost of Goods Sold)
The direct costs of delivering your product to customers. For SaaS, COGS typically includes hosting, third-party software, customer support, and payment processing fees.
DefinitionConvertible Note
A short-term debt instrument that converts into equity at a future financing round, usually at a discount. Convertible notes defer valuation negotiations and are common in seed-stage fundraising.
Definition
E
EBITDA
Earnings Before Interest, Taxes, Depreciation, and Amortization. EBITDA approximates operating cash flow and is used to compare profitability across companies regardless of capital structure.
CalculatorEBITDA Margin
EBITDA expressed as a percentage of total revenue. EBITDA margin measures operating profitability and is a key input to the Rule of 40 and SaaS valuation multiples.
CalculatorEquity Dilution
The reduction in ownership percentage that occurs when new shares are issued during a funding round. Dilution is the trade-off founders accept in exchange for growth capital.
CalculatorExpansion Revenue
Additional revenue earned from existing customers through upsells, cross-sells, or plan upgrades. Expansion revenue is a key driver of net revenue retention above 100%.
Definition
G
Gross Margin
Revenue minus COGS, expressed as a percentage. SaaS companies typically target gross margins of 70-85%, which reflects the scalability advantage of software delivery.
DefinitionGross Revenue Retention (GRR)
The percentage of recurring revenue retained from existing customers excluding any expansion revenue. GRR isolates your ability to keep customers from downgrading or churning.
Definition
I
L
Line of Credit
A flexible borrowing arrangement that lets you draw funds up to a set limit and pay interest only on the amount used. For SaaS companies, lines of credit provide working capital for variable expenses without a fixed repayment schedule.
GuideLogo Churn
The percentage of customer accounts (logos) lost during a period, regardless of their revenue contribution. Logo churn differs from revenue churn because losing a small customer counts the same as a large one.
DefinitionLTV (Customer Lifetime Value)
The total revenue a customer generates over their entire relationship with your company. LTV is calculated from ARPU, gross margin, and churn rate, and is essential for understanding customer profitability.
CalculatorLTV:CAC Ratio
The ratio of customer lifetime value to customer acquisition cost. A healthy SaaS LTV:CAC ratio is typically 3:1 or higher, indicating you earn three dollars for every dollar spent acquiring a customer.
Calculator
M
Markup
The percentage added to the cost of a product or service to determine its selling price. In SaaS, markup reflects the relationship between COGS and subscription pricing.
CalculatorMerchant Cash Advance
A lump sum advance in exchange for a percentage of future sales until the advance plus fees is repaid. MCAs offer fast funding but at higher effective costs than revenue-based financing.
GuideMRR (Monthly Recurring Revenue)
The predictable revenue your business earns each month from active subscriptions. MRR breaks down into new, expansion, contraction, and churned components.
Calculator
N
Net Revenue Retention (NRR)
The percentage of recurring revenue retained from existing customers over a period, including expansions, contractions, and churn. NRR above 100% means you grow even without new customers.
CalculatorNon-Dilutive Funding
Capital that does not require giving up equity in your company — including revenue-based financing, term loans, grants, and debt instruments. Non-dilutive funding lets founders scale while retaining full ownership.
Guide
P
R
Recurring Revenue
The portion of revenue that repeats predictably each billing period. Recurring revenue is the foundation of SaaS business models and the primary reason they command higher valuation multiples.
DefinitionRevenue Based Financing
A funding model where investors provide capital in exchange for a percentage of ongoing revenue until a predetermined amount is repaid. It is non-dilutive and aligned with your cash flow.
GuideRule of 40
A benchmark that says a healthy SaaS company should have its revenue growth rate plus profit margin equal or exceed 40%. It balances growth against profitability.
Definition
S
SaaS Accounting
The accounting practices specific to subscription software businesses, including revenue recognition (ASC 606), deferred revenue, and the treatment of capitalized development costs.
ArticleSaaS Financial Model
A spreadsheet-based framework that projects revenue, expenses, cash flow, and key metrics over time. SaaS financial models are built around recurring revenue dynamics and are essential for fundraising and planning.
ArticleSaaS Financing
Funding options specifically structured for subscription software businesses, using recurring revenue as collateral instead of physical assets. Includes revenue-based financing, venture debt, SBA loans, and more.
ArticleSaaS Growth Rate
The rate at which your recurring revenue increases over time, typically measured month-over-month or year-over-year. Growth rate is the primary driver of SaaS valuation multiples.
CalculatorSaaS KPIs
The key performance indicators that SaaS companies track to measure business health — including MRR, churn, CAC, LTV, NRR, and gross margin. KPIs guide operational decisions and investor reporting.
ArticleSaaS Multiples
The revenue or earnings multiples used to value SaaS companies, typically expressed as a multiple of ARR. Multiples vary based on growth rate, retention, margins, and market conditions.
ArticleSaaS Valuation
The estimated market value of a SaaS company, typically expressed as a multiple of ARR. Valuation multiples vary based on growth rate, retention, margins, and market conditions.
CalculatorSAFE Note
A Simple Agreement for Future Equity — a Y Combinator-created instrument that gives investors the right to future equity without setting a valuation upfront. Unlike convertible notes, SAFEs carry no interest rate and no maturity date, making them the simplest early-stage funding instrument.

Venture Capital
Equity financing from institutional investors who provide capital in exchange for ownership stakes in high-growth startups. VC funding typically involves board seats, governance rights, and pressure for rapid scaling toward a large exit.
GuideVenture Debt
A form of debt financing for venture-backed startups, typically structured as a term loan with warrants. Venture debt supplements equity rounds and extends runway without additional dilution.

SaaS Finance Terms Every Founder Should Know
See your terms in
under five minutes.
No pitch deck, no scarcity, no countdowns. Connect your data and we'll show you exactly what you qualify for — every figure disclosed up front.
Investors typically start with five metrics: ARR (or MRR) for scale, growth rate for trajectory, net revenue retention for stickiness, gross margin for efficiency, and burn multiple for capital discipline. Together they paint a quick picture of whether a SaaS business is fundable. You can calculate most of these with our free SaaS calculators.
Many terms link directly to a resource where you can apply the concept — a free calculator, a detailed guide, or an in-depth article. Each linked term is labelled with the type of resource it opens — Calculator, Guide, Article, or Definition. Terms without a label provide a concise definition on the page itself.
Dilutive funding — such as venture capital or angel rounds — requires giving up equity in exchange for capital. Non-dilutive funding — including revenue-based financing, term loans, and grants — lets you raise capital while retaining full ownership. Founderpath specializes in non-dilutive options for bootstrapped and capital-efficient SaaS companies.
It is built for SaaS founders, finance leads, and operators who need clear, no-jargon definitions of the metrics and financial concepts that come up in board decks, investor conversations, and day-to-day performance tracking.
SaaS companies raising working capital typically choose from revenue-based financing, term loans, a revolving line of credit, or a same-day advance against booked revenue. Commercial lenders that focus on SaaS underwrite against recurring revenue and retention rather than collateral or a personal guarantee, so cash flow and churn matter more than the balance sheet. Founderpath offers all of these as non-dilutive capital — you keep 100% ownership while funding growth, payroll, or a cash gap.
SaaS acquisition financing is capital used to buy an existing SaaS business or fund a founder buyout, rather than to grow one organically. It is usually structured as a term loan or seller note sized against the target's ARR and cash flow, since SaaS companies rarely have hard assets to use as collateral. Buyers favor non-dilutive structures here specifically because acquisition deals are already equity-intensive — adding venture debt or an equity co-investor on top further dilutes the acquirer's return.
