About DealSheet Tools

DealSheet Tools is a set of free calculators for people investing in US residential real estate: rentals, fix-and-flips and BRRRR deals.

Each calculator shows the formula it uses and a worked example, so you can follow the math instead of trusting a black box. Everything is calculated in your browser; nothing you type is sent to us or stored.

The numbers are estimates for screening and learning. Before buying a property, confirm costs with lenders, insurers, contractors and a tax professional.

For spreadsheet versions you can save and share, see the DealSheet investor toolkit.
