About this calculator

A deposit calculator splits a property purchase price into the deposit you'll put down and the bond you'll need to finance. Enter the property price and the deposit either as a percentage or as a Rand amount, and the calculator shows the resulting loan amount you'll need.

In South Africa, a 10% deposit has traditionally been the target for the best interest rates. Banks price bonds relative to loan-to-value (LTV): a 90% LTV bond typically prices below a 100% LTV bond, so a bigger deposit saves you interest over the life of the loan as well as reducing the principal.

That said, many first-time buyers with strong credit successfully secure 100% bonds — the deposit isn't strictly required, though it does open access to better rates. Remember that the deposit is only part of the upfront cash: you also need transfer duty (see our SARS calculator), attorney fees, bond registration costs and Deeds Office charges, which together can add 8–12% on top of the deposit for a residential purchase.

How to use it

  1. 1Enter the property price. The agreed purchase price of the property.
  2. 2Enter the deposit percentage. The share of the price you'll pay upfront.
  3. 3Read the deposit amount. The Rand deposit you need in cash.
  4. 4Read the loan amount. The bond principal you'll need to finance.

How it works

The calculator splits a property purchase into a deposit component and a loan component. The deposit percentage you enter is multiplied by the price to give the cash you need upfront; the remainder becomes the bond you must apply for.

In South Africa, the standard target is a 10% deposit, but 100% bonds are common for first-time buyers with strong credit. A bigger deposit lowers the loan-to-value ratio, which banks reward with better interest rate pricing — and it lowers the monthly instalment through both a smaller principal and a lower rate.

Formula

Deposit = Price × Deposit%; Loan = Price − Deposit

Price = purchase price; Deposit% = the percentage you're putting down; Loan = bond principal you'll need.

Worked examples

R1.5m property, 10% deposit

Deposit = R150,000. Bond needed = R1,350,000.

R2.5m property, 20% deposit

Deposit = R500,000. Bond needed = R2,000,000.

Frequently asked questions

How much deposit do I need in South Africa?

10% is the traditional target for a favourable interest rate, but many first-time buyers get 100% bonds if their credit profile is strong.

Does a bigger deposit lower my interest rate?

Usually yes. Banks price risk based on loan-to-value (LTV) — a 90% LTV bond typically prices better than a 100% LTV bond.

What else do I need cash for?

Transfer duty (see our SARS calculator), bond registration, attorney fees, moving costs and initial rates/levy invoices. Budget 8–12% of the price on top of the deposit.

Can I use my Tax-Free Savings for a deposit?

Yes, but you can't recontribute what you withdraw — you lose that lifetime TFSA allowance permanently.

Is a bigger deposit always better?

Only up to the point that you're not depleting your emergency fund. Keep 3–6 months of expenses liquid.
