Enter monthly income, recurring obligations, and the rent under consideration to see the rent-to-income ratio and the money left over.
The 30% benchmark is a convention drawn from US housing data, not a legal standard.
The calculator shows two numbers. Rent-to-income is rent divided by gross monthly income — the 30% rule of thumb comes from decades of US housing statistics, not from any law. Residual income is what remains after rent and the obligations you entered, which is often the more useful number for a landlord deciding whether a tenancy is sustainable.
An applicant at 35% rent-to-income with no debt may be far safer than one at 28% carrying a car loan and student loans.
Check an applicant's income multiple, or work backwards from the multiple you require.
Total everything due at signing — rent, prorated rent, deposit, fees and custom charges.
Choose exactly how you qualify applicants and generate a written requirements sheet.
Work out a partial month at move-in or move-out using the method your lease specifies.
Calculate a deposit from a multiple of rent and see it as an annual cost to the tenant.
Model a flat, percentage, or per-day late fee against a grace period.
