Calculators
Use the Karpata calculator hub to model loan structure, property cash flow and project economics before requesting a financing review.
Choose the analysis that matches the deal.
Each calculator answers a specific investor question. Start with the appropriate model, change the assumptions, then bring the results into the Deal Lab when you are ready for actual lender screening.
Run the numbers before you commit capital.
Change assumptions instantly and see how leverage, rate, term, fees and property performance affect the deal.
Calculator results are educational estimates. Actual lender eligibility, pricing and terms require underwriting.
