Frequently Asked Questions

Equal installment vs. equal principal — which saves more?

Equal-principal pays less total interest (principal is constant, interest shrinks monthly) but front-loads payments; equal-installment keeps monthly payments fixed with slightly higher total interest. Choose equal-installment if cash flow matters, equal-principal if you can absorb higher early payments and want to minimize interest.

How much interest can early repayment save?

The earlier and larger, the more you save. A $1M/30-year loan with $200K prepaid at year 5 (shorten-term method) saves roughly $300-400K. Use the 'early repayment' module: input remaining term, amount, and rate for a precise figure.

What if the result differs from my bank's quote?

The tool uses standard formulas (equal installment / equal principal), identical to bank algorithms. Banks may add service fees, insurance, or registration fees. Your signed contract is the final source of truth.
