One thing all innovators will agree with is that it takes money, and sometimes lots of it, to bring a brilliant idea to market.
As well as research and development, then commercialisation, there’s the cost of facilities, raw materials, transport, staff, marketing and sales, and distribution. Bootstrapping can go a long way, as can grants, and income-generating strategies such as commercialising your IP, but at some stage most founders need to raise extra capital and they start looking at their options.
Different forms of capital carry different costs, and it’s worth remembering that the cost might not be immediately obvious or upfront. To help you weigh up your options, this blog looks at the cost of capital, including some of the key reasons why waiting for funding can cost you more than you think.
Australian innovators need capital injections more than ever
More than 1 in 4 Australian founders cite funding as one of their top 2 challenges (behind customer acquisition and marketing at number 1) and more than half plan to raise capital this year. [1]
Given that venture capital in Australia is concentrated at the top end, with 58% of all capital raised in 2025 going to only 20 companies, [2] and that it’s taking longer than ever to raise capital, many founders are looking for additional sources of capital to supplement business funds and extend runway.
Grants can be time-consuming to apply for, often require you to match funds, and can carry onerous conditions. Banks won’t talk to you until you have proof of concept or assets; personal loans can literally risk your family home; and, depending on your stage, growth trajectory or product, you might not fit the business or founder profile VCs are looking for. One form of funding gaining more attention from early-stage and scale-up businesses is debt financing. While debt financing comes in many forms, from loans and credit cards to revenue-based financing, one type that’s fast to access and increasingly popular with innovation-driven businesses is R&D finance. This is where companies claiming the R&D tax incentive (R&DTI) gain early access to their expected refund through a short-term loan. Radium Capital is Australia’s largest R&D lender, having deployed more than $1.1 billion in Radium Advances since 2007.
Not all capital costs the same
When founders compare funding options, the focus is often on the most obvious costs: interest rates, fees, or the amount of equity they might need to give away.
But the true cost of capital is often much broader than that. The decisions you make about funding today can continue to affect your business for years to come.
We’ve unpacked some of these short and long-term considerations in our blog Debt vs equity: the true cost of capital for founders, which includes calculations on what various forms of capital may cost in financial terms.
However, costs realised at exit, as well as fees and interest rates, are only part of the picture. Different forms of capital can also carry hidden costs: some capital costs more in time and effort to secure, which means you need to consider the lost opportunity cost of waiting or business disruptions, and others result in reduced flexibility and control.
In this blog we explore some of the hidden costs of capital, including the impact of time, dilution, uncertainty and missed opportunity, and why founders should consider more than just the financial costs when evaluating funding options.
Weighing up the cost of waiting
One of the biggest hidden costs of raising capital is time. Every minute spent raising capital is time not spent on developing your product, reaching new customers, hiring key staff, or commercialising your innovation.
Some funding options also require a significant investment of founder and management time. Preparing investor materials or project documentation, refining financial forecasts, attending meetings, responding to due diligence requests, and negotiating terms can become a major focus for leadership teams, particularly during a capital raise.
Grant applications usually involve several submission stages – an eligibility screen, a merit assessment, and sometimes even ministerial sign-off – and take at least a month for the smallest programs and up to a year for programs larger than $500k.[3] For VC funding, the timeline from first conversation to receiving funding has extended from 6 months to 12, while the interval between rounds has also increased. [4] In Q4 2024, the interval from Seed Round to Series A had increased to around 2.1 years, up from around 1.2 years in Q4 2021. [5]
When choosing how to inject capital into your business, it’s worth considering both the cost of securing the funding and the cost of waiting for it to arrive. The time spent preparing applications, pitching investors, and navigating due diligence is time that can’t be spent building the business. Will waiting mean your competitor reaches the market first, or that you miss a critical commercial window?
Risking dilution and loss of control
Another hidden cost of capital can be the equity and control you give up to secure it.
Raising Venture Capital (VC) comes with the cost of dilution, which is amplified if you raise too early in your journey. In the early stages, many businesses are still working toward proof points that can influence valuation: technical milestones, customer traction, regulatory approvals, commercial partnerships, or early revenue. Until those milestones are reached, investors are taking on more risk and the company has a lower valuation, which often means founders need to give up a larger share of equity for a smaller amount of capital. That can have a compounding effect over time. The earlier and more frequently founders dilute, the less ownership they retain as the business grows.
Equity funding can also influence how decisions are made. As new investors join the cap table, founders may find themselves balancing their own vision for the business with the expectations, priorities, and return horizons of external shareholders. While many investors bring valuable expertise and strategic support, founders should consider how governance and decision-making arrangements may evolve over time and the cost of seeking VC too early.
Considering the cost of funding uncertainty
Another often-overlooked cost of capital is uncertainty. Different forms of capital carry different levels of certainty around whether you’ll receive the money or not.
Grant funding can be highly competitive and difficult to predict. Venture capital raising can take months and depends on market conditions, investor appetite, and timing. Traditional lending may require personal guarantees or assets that many early-stage businesses simply do not have.
That uncertainty carries its own cost. Founders can spend significant time chasing funding without knowing whether it will land, when it will arrive, or what trade-offs will ultimately come with it.
Uncertainty can leave businesses operating in limbo. Hiring decisions may be delayed, product roadmaps can stall, and commercial opportunities may be deferred while founders wait for clarity on their funding position. In some cases, businesses become reluctant to commit to growth initiatives or strategic investments because they simply don’t know when capital will become available, or whether it will arrive at all.
Why faster access to capital matters
When cash flow is tight, the timing of funding can have a significant impact on business decisions. With runways shortening and burn rates rising, founders are increasingly looking at ways to cut costs, most commonly by “increasing prices (42%), scaling back or delaying expansion plans (37%), cutting marketing spend (35%), raising bridge funding (33%), and reducing headcount (33%).” [6]
There’s also the human cost: founders are taking on more and risking burnout. Startup mentor Pauline Fetaui says financial pressure can lead to founders “doing more themselves, delaying non-essential work, using AI to take on tasks that used to require contractors, or relying on lighter touch support to preserve cash.” [7]
And when you’re creating something new, cutting back on R&D because of cash flow pressure can delay milestones and weaken your competitive position.
R&D financing as a funding solution
For businesses eligible for the R&DTI, R&D financing offers a different model, allowing companies to access funding linked to eligible R&D expenditure they have already incurred. It’s a flexible, reliable funding solution.
Because they’re effectively accessing their own capital, early, businesses can decide to take an R&D advance when, and how often, it makes the most sense to do so. Plus, they can choose what they spend the capital on: whether that’s hiring staff, marketing, expanding premises, or reinvesting into R&D, there are no rules about how you use your R&D advance in your business.
And, because the interest and fees are visible from the outset, you can build the costs of accessing the capital into your financial planning.
R&D finance is predictable money you know you can count on. It allows you to avoid the delays, dilution, or uncertainty that can come with other forms of funding. The cash flow certainty and flexibility offered by R&D finance can help businesses keep investing in R&D, move faster towards commercial milestones, hire at the right time, or act on opportunities as they arise rather than months later.
Compounding the benefit of R&D finance
One of the unique features of R&D financing is that businesses can benefit from a compounding effect if they reinvest the funds into further eligible R&D activities. Increasing your R&D spend this way results in a larger R&DTI refund, creating a cycle where earlier access to funding helps support ongoing investment in innovation.
For example, imagine that the fictional company Accelerate plans to spend $400,000 on R&D across the financial year, investing $100,000 of its own funds per quarter. Each quarter, Accelerate gains early access to its accruing R&DTI refund with a Radium Advance, reinvesting those funds into the next quarter’s R&D budget, and adding it to their planned $100,000. Because they are spending more on R&D each quarter, the Radium Advance available also increases.
- Q2: After spending $100,000 in Q1, Accelerate accesses a Radium Advance of $34,800. They are eligible for a R&DTI refund of 43.5% and able to access 80% of their accrued R&DTI refund for that quarter through Radium Advances. They add the funds from the Radium Advance to their planned budget of $100,000 for Q2.
- Q3: After spending $134,800k in Q2, Accelerate is now eligible for $46,910 in Radium Advances.
The pattern continues with a compounding effect. Over the year, by taking quarterly advances and reinvesting them back into eligible R&D, Accelerate increases its total annual R&D budget by more than 33% to $532,835, and in turn increases its expected R&DTI refund from $174,000 to $231,783.
Reinvesting regular Radium Advances into eligible R&D activities amplifies the benefit of R&D financing and allows companies to reach critical milestones earlier.
Building R&D financing into your capital stack
Different forms of capital solve different problems, which is why building a diverse capital stack can give you a strategic advantage. Rather than relying on a single source of funding, many innovative companies combine different forms of capital at different stages of their growth journey, depending on what they need at the time.
An R&D advance is not designed to replace other sources of capital. Instead, it complements them and can form part of a broader funding strategy that may also include equity, grants, revenue, debt, or other sources of capital. Equity can help businesses pursue large growth opportunities, grants can support specific projects, and revenue can fund ongoing operations. R&D finance provides access to non-dilutive capital that is timely, flexible, and predictable.
The key is understanding which funding option is best suited to the opportunity in front of you and when to leverage it.
Considering the hidden cost of capital
When evaluating different capital options, it’s important to consider both the costs that are easy to quantify and those that are harder to measure.
Interest, fees, legal expenses, and repayments are usually visible from the start. Other costs, such as the executive team’s time, dilution, reduced flexibility, uncertainty, or delays in accessing capital, can be just as significant. One of the most important costs to consider is the opportunity cost of slowing down while waiting for funding to arrive.
The right funding option will depend on your business, your objectives, and where you are in your growth journey at any given point in time. Consider the costs – both upfront and hidden – of different types of capital before deciding which funding lever to pull.
The most effective funding decisions are rarely based on cost alone. Instead, they are based on choosing the right source of capital at the right time to support the goals of the business.
