Climate Tech Grant Runway & Match Calculator
Don’t get caught in the reimbursement gap. Accurately model your bank cash runway across US and European grants accounting for 60–90 day payment delays, matching cost-share, and indirect rates.
Before Grant — Cash & Operating Burn
Your current bank balance and non-grant monthly overhead before any grant funding is applied.
With Grant — Award Rules, Drawdown & Cost-Share
Select your region and grant rules to see how reimbursement delays and mandatory matching change your actual cash balance.
20% company non-federal co-funding
Lag between spending company cash and receiving drawdown reimbursement.
Federally negotiated (NICRA) or de minimis overhead rate.
Deficit at Month 36!
Private non-federal capital required over project lifecycle
Net non-dilutive capital reimbursed to your bank
Critical Working Capital Gap Detected
Your cash balance is projected to dip into a deficit of $1,118,000 around Month 36 due to the reimbursement delay before federal/EU drawdowns land.

The Hidden Financial Traps of Non-Dilutive Climate Grants
Over 60% of early-stage climate tech startups miscalculate their true cash runway when awarded government grants. Here is why:
1. The Reimbursement Lag
Federal programs (like DOE and SBIR) require you to incur expenses and pay vendor invoices upfront before submitting drawdown requests. Review and disbursement can take 60 to 90 days, creating a working capital deficit.
2. Mandatory Match (Cost-Share)
Most major demonstration grants (DOE SCALEUP, Horizon Europe EIC, Innovate UK) require 20% to 50% non-federal matching funds. You must prove you have liquid matching reserves to claim the grant.
3. Audit & Time-Tracking Rules
Grants require compliant time-tracking, direct-vs-indirect expense segregation, and FAR 31.2 cost principles. Disallowed expenses must be refunded out of company equity reserves.
Methodology, Regulatory Frameworks & Statutory Sources
All default preset values, drawdown mechanics, and cost-share constraints in this calculator are derived directly from published US federal and European regulatory frameworks:
- SBIR/STTR Policy Directive (15 U.S.C. § 638): Statutory award limits ($275k Phase I, $1.5M Phase II) with 0% mandatory cost sharing.
- DOE Financial Assistance Rules (2 CFR 910): Mandatory 20% to 50% non-federal cost-share on demonstration grants and ASAP.gov drawdown lags.
- Indirect Cost Allocation (FAR 31.2 / 2 CFR 200.414): Standard 10–15% de minimis and 20–35% Negotiated Indirect Cost Rate Agreements (NICRA).
- EIC Accelerator (Horizon Europe Work Programme): Up to €2.5M grant at a 70% funding rate (30% mandatory beneficiary co-financing) + 25% flat indirect rate.
- Innovate UK General Guidance (UKRI): SME 70% funding cap with claims paid in arrears following Independent Accountant Reports (IAR).
- Eurostars / Eureka: 50% co-funding requirement for cross-border industrial research consortia.
Frequently Asked Questions
Everything you need to know about climate grant cash flow modeling.
Why does reimbursement lag create a working capital dip?
Because government agencies reimburse on invoice submission rather than prepaying. If your monthly direct project spend is $100k and the reimbursement lag is 2 months, you must float $200k in cash out of your company bank account before the first reimbursement check clears.
How can a startup bridge the grant reimbursement gap?
Startups commonly use non-dilutive working capital lines, venture debt, R&D tax credit advances, or milestone-based private SAFE notes to float the 60–90 day drawdown gap.
What is the difference between direct and indirect grant costs?
Direct costs are directly attributable to the grant research (e.g. dedicated engineer hours, lab consumables). Indirect costs are general business overhead (e.g. office rent, executive salaries, accounting software) recovered via a negotiated NICRA or standard percentage rate.
