What is a House Affordability Calculator?

A house affordability calculator determines the maximum home price you can qualify for based on your income, debts, down payment, and interest rate. Lenders use two key ratios: front-end (housing costs/income) and back-end (all debts/income).

Formula

Front-End Max Payment = Monthly Income x 28%
Back-End Max Payment = Monthly Income x 36% - Monthly Debts
Max Payment = min(Front-End, Back-End)
Max Home Price = Down Payment + (Max Payment can service as mortgage loan)

Examples

US — $120K income, $500/mo debts, $60K down, 6.5% rate, 30yr

Max home price: ~$480K | Max payment: $2,800/mo | Front-end: $2,800 | Back-end: $3,100

India — Rs 15L income/year, Rs 20K/mo existing EMIs, Rs 20L down, 8.5% rate, 20yr

Max home price: ~Rs 85L | Eligible loan: ~Rs 65L | EMI: ~Rs 56,000/mo

Example — Canada

C$100,000 gross income, C$600/month debts, C$60,000 down, 5.5% rate, 25-year amortisation. Max home: C$465,000 | Monthly payment: C$2,450 | GDS ratio: 28%

Why Use This?

Knowing your maximum affords you negotiating power. But just because you can afford the maximum doesn't mean you should — leave room for emergencies, investment, and lifestyle.

What is the 28/36 rule?▼

Spend no more than 28% of gross monthly income on housing costs (front-end ratio) and no more than 36% on all debts combined (back-end DTI). These are standard US lender guidelines.

How does my credit score affect affordability?▼

Excellent credit (760+) gets the best rates. A 1% rate difference on a $400K mortgage changes your payment by ~$230/mo and affordability by ~$40K.

Should I use the maximum I qualify for?▼

No — qualify conservatively. Aim for housing costs under 25% of take-home pay (not gross income). This leaves room for savings, emergencies, and not being 'house poor'.

💡 Tip: The real monthly cost of homeownership is typically 25-30% higher than just the mortgage — add taxes, insurance, and maintenance.
