Mortgage Outstanding Balance

At a glance:The Real Estate Cost Calculator quantifies the full cost of buying — down payment, one-time closing costs and monthly P&I, rates and insurance — so you can assess the cash required and the monthly burden, not just price and mortgage.

Formula

r = annual ÷ 100 ÷ 12; n = years × 12.

Down = price × down%; loan = price − down.

Monthly P&I = loan × r × (1+r)^n ÷ ((1+r)^n − 1).

Closing costs = price × closing%; cash needed = down + closing.

Monthly PITI = P&I + monthly tax + monthly insurance.

How to Use

  1. Enter property price, down payment %, mortgage rate and term.
  2. Estimate the closing-cost % (legal, stamp duty, commission, insurance).
  3. Add yearly rates/tax and insurance to see monthly outlay and total cash needed.

FAQ

What do closing costs usually include?

One-time costs at completion: solicitor fees, ad valorem/property stamp duty, agent commission (often ~1% each side), mortgage insurance (for high LTV), valuation and deed fees. In Hong Kong the stamp duty is a large slice; this calculator uses a rough percentage — use professional quotes for accuracy.

Why look at cash needed rather than just the down payment?

At completion you pay the down payment AND the closing costs together. Budgeting only the down payment risks a cash shortfall on the day. Adding them shows the true liquid funds required and whether monthly PITI fits your affordability.

How is this different from a mortgage calculator?

A mortgage calculator focuses on monthly payment and interest; this tool combines upfront and monthly holding costs for a fuller home-buying budget, useful before deciding to enter the market.
