Our approach
Numbers you can understand.
RightFigures helps you explore the costs behind important decisions. We start with useful calculations, then explain the assumptions and limitations that give the result context.
Clear methods
Each calculator provides its formula, an example and public sources for relevant concepts. Calculations run as deterministic code in your browser. An AI model does not generate your financial results.
Checked, with limits
Our mortgage engine is checked against reference cases and an independent monthly-balance calculation. Automated tests cover invalid values, precision and browser interaction. Testing does not make an estimate a lender quote or a personal recommendation.
A focused collection
Our first tool estimates a fixed-rate mortgage payment and its recurring housing costs. Additional calculators will be published when their methods and user experience have been reviewed.
Privacy by design
We do not require an account or store your calculator values. Read about privacy and usage analytics.
