How to use your SR&ED calculator result
The result is an early planning figure. A supportable claim still depends on the eligible work, the company making the claim, the costs it paid, any assistance it received, and the records behind those amounts.
Confirm the work
Separate experiments and directly supporting work from routine production, testing, administration, and commercial activity.
Confirm the claimant
Check which company undertook the work, paid the expenditures, and is named in any research, employment, or contractor agreements.
Adjust the inputs
Government assistance, contract payments, taxable income, company status, expenditure limits, and provincial rules can change the final credit.
FAQ
SR&ED calculator questions
What does this SR&ED calculator estimate?
It estimates the federal investment tax credit and the selected provincial or territorial credit using the salary, contractor, and material cost assumptions you enter.
Can businesses in any industry use it?
Yes. SR&ED is not limited to one industry. Eligibility depends on the experimental work, claimant, expenditures, assistance, evidence, and filing position.
Which federal SR&ED rate should I select?
Use the 35% enhanced rate only when the claimant meets the enhanced investment tax credit requirements. Otherwise, select the 15% basic rate.
How should I use the estimate?
Use it to size a potential opportunity and compare assumptions. A claim review then confirms the underlying work, costs, company facts, assistance, evidence, and applicable program rules.
Does the calculator account for grants or other assistance?
No. Government and non-government assistance can reduce SR&ED expenditures or qualified expenditures. Review each funding agreement before relying on the estimate.
Is the estimate the same as a cash refund?
Not necessarily. Refundability depends on the claimant, federal rate, provincial program, expenditure limits, taxable income, and other company facts. The calculator shows an illustration, not a filed tax position.
How the estimate works

Federal model
Uses the selected 35% enhanced or 15% basic ITC rate, a 55% prescribed proxy amount on eligible salary, and 80% of qualifying arm's-length contract payments.
Provincial model
Shows published refundable base rates and common caps. Company size, taxable income, prior spending, and provincial rules can change the result.
Quebec CRIC
Uses 30% on eligible labour plus 50% of qualifying Quebec subcontract payments above a simplified $50,000 minimum exclusion. The actual threshold can be higher.
