Purchase planning

Down Payment Calculator

Calculate down payment, loan amount, LTV and whether available cash covers the target.

Why LTV matters

Loan-to-value ratio compares the loan amount with the purchase price. Lower LTV can affect approval, mortgage insurance and rate offers.

Example

For a 400,000 purchase with a 20% down payment target, the down payment is 80,000 and the starting loan amount is 320,000. If available cash is 60,000, the cash gap is 20,000 before closing costs.

Common mistakes

Do not spend every available cash unit on the down payment if closing costs, moving costs, repairs or emergency savings still need funding.

Limitations

This does not include closing costs, taxes, appraisal gaps, mortgage insurance, grants, seller credits or local lending rules.
