In-Principle Approval (IPA) Estimator Singapore 2026
Estimate Your Bank Pre-Approval Budget — TDSR, MSR, LTV & Upfront Cost Summary
Estimate the In-Principle Approval (IPA) amount a Singapore bank would likely grant you before you start property hunting. An IPA (also called Approval-in-Principle or AIP) is a conditional letter from the bank stating the maximum loan they are willing to extend based on your income, debts, age, and the loan type. This calculator combines TDSR (55%), MSR (30% for HDB/EC), LTV (75%/55% based on age rule), and the applicable assessment rate to produce a realistic IPA estimate — plus the total upfront costs you should budget (down payment, BSD, legal fees).
Banks count 70% of variable income (30% haircut). Include bonuses, commissions, overtime averaged monthly.
Total outstanding balance. Banks deem 3.5% as the monthly obligation for TDSR.
Enter your income, age, debts, and loan preferences to see the estimated IPA amount a bank would approve, plus the maximum property price and total upfront costs.
In-Principle Approval (IPA) Singapore 2026 — What It Is, Why You Need One Before House Hunting
An In-Principle Approval (IPA), also called Approval-in-Principle (AIP), is a conditional letter from a bank stating the maximum loan amount they are willing to extend to you, subject to the property meeting their requirements. It is not a binding commitment — either you or the bank can walk away. But it serves a critical purpose: it tells you your realistic property budget before you start viewing properties, preventing the common mistake of falling in love with a property you cannot afford. An IPA typically takes 3–7 working days to process, is free of charge, involves no commitment, and is valid for 30–90 days depending on the bank. Every serious property buyer should obtain at least one IPA before entering the market.
How Banks Calculate Your IPA Amount
| Assessment Factor | What the Bank Checks | Impact on IPA |
|---|---|---|
| TDSR (55%) | All monthly debts cannot exceed 55% of gross income | Primary constraint for private |
| MSR (30%) | Mortgage alone cannot exceed 30% of income (HDB/EC) | Often the tighter gate |
| Stress-test rate | Variable loans assessed at max(actual, 4%) | Reduces IPA vs fixed-rate |
| LTV (75%/55%) | Age + tenure determines 75% or 55% LTV | Affects DP, not loan directly |
| Credit score | CBS credit report (Grade AA to HH) | Must be acceptable |
| Employment stability | Probation period, job tenure | Affects approval likelihood |
How This IPA Estimator Works — Income to Pre-Approval Amount in 3 Steps
Step 1 — Enter Income, Age and Debts
Enter your gross income (fixed + variable with 70% haircut), age, desired tenure, property type, and all existing monthly debts. The calculator applies TDSR (55%) and MSR (30% for HDB/EC) ceilings, subtracts existing debts, and derives the maximum mortgage instalment the bank would allow.
Step 2 — See the Estimated IPA Amount
The calculator back-calculates the maximum loan from the allowed instalment at the applicable assessment rate (4% stress for variable, actual rate for fixed/HDB). It then applies the LTV (75% or 55% based on age+tenure) to derive the maximum property price. The result is presented as an IPA-style summary: max loan, max property, binding constraint, and LTV tier.
Step 3 — Review Upfront Costs and Rate Comparison
The calculator adds down payment, BSD, and estimated legal fees to show your total upfront requirement. The rate comparison box shows how the IPA amount differs at HDB 2.6%, bank fixed 3.2%, and SORA stress 4% — so you can see how much the loan type affects your approved budget.

3 Expert IPA Tips — Apply to Multiple Banks, Clean Your Credit & the IPA as Negotiation Tool
Apply to 2–3 Banks for the Best IPA Amount
Different banks may offer different IPA amounts because they interpret income documentation differently, apply different internal credit policies, and offer different rates/spreads. Bank A might count your overtime income at 70%, while Bank B counts it at 50%. Bank C might offer a lower spread, resulting in a higher IPA at the same TDSR assessment. Applying to multiple banks is free, does not affect your credit score significantly, and gives you a range of approved amounts to work with. Use a mortgage broker to submit to multiple banks simultaneously — they do the comparison for you and can negotiate spreads.
Clean Your Credit Bureau Report Before Applying
Before applying for an IPA, check your CBS (Credit Bureau Singapore) report (available for S$8 at creditbureau.sg). Clear any outstanding balances, correct errors, and ensure all closed accounts are properly reflected. A credit grade of AA or BB improves approval speed and may qualify you for better rates. Key items banks flag: late payments in the last 12 months, high credit utilisation (using more than 30% of credit limits), too many recent credit applications, and undischarged bankruptcies. Cleaning your credit 3–6 months before applying gives time for improvements to reflect in the score.
Use the IPA Letter as a Negotiation Tool with Sellers
An IPA letter demonstrates to the seller (or their agent) that you are a serious, financially qualified buyer. In competitive bidding situations, buyers with IPA letters are preferred over buyers without — because the seller knows the deal is less likely to fall through due to financing issues. Some agents even require proof of IPA before arranging viewings of high-demand properties. The IPA also gives you a clear budget ceiling, preventing emotional overbidding. When making an offer, showing the IPA builds credibility and can sometimes tip the negotiation in your favour over competing buyers who lack pre-approval.
