Funding, ROI & Valuation Calculators

Five calculators and seven guides that answer the big-decision questions in business finance — whether to take a loan, whether an investment is worth making, what your business is worth to a buyer, and whether your growth rate matches investor expectations.

These are the calculations behind every major financial decision a business owner makes. The ROI Calculator and Payback Period Calculator answer the same question from two angles — total return and speed of recovery. The Business Loan Calculator produces a monthly payment and amortisation table for any loan amount and term. The Business Valuation Calculator runs three valuation methods side-by-side so you can defend an asking price.

Use the calculators alongside the guides. The payback-vs-ROI article explains which metric to use when. The how-to-value-a-business article walks through the multiples buyers actually pay (most owners overestimate by 50%+). The SBA vs conventional loan article compares total cost on a $200k example — the answer is often surprising.

Whether you're raising capital, deploying capital, or preparing to exit, the maths starts here.
