About this tool
Find a comfortable rent for your income, and compare total rent with mortgage payments over the same years.
Affordable rent = monthly income × your rent share. Rent over N years grows by the yearly increase: total = 12·R·((1+g)^N − 1)/g. Buying counts the down payment plus N years of payments.
Formula: Rent ≤ Income × share · Σ rent = 12·R·((1+g)^N − 1)/g
Example: What do you want to calculate? = Affordable rent, Monthly income = 5,000, Share of income for rent = 30 → Comfortable monthly rent = 1,500.
The comparison shows cash paid only. Home equity, price changes, maintenance and investment returns are not modelled.
