Baseline
Normal mortgage payment with no extra principal. Use this as your reference line for time saved and interest saved.
Do this in simulator: Extra Monthly = 0, Annual Lump Sum = 0, Yearly Position Buy = 0%, One-time Year = 0, One-time Amount = 0, Biweekly = Off.
Best for: Cash-tight periods or conservative planning.
Monthly Booster
Adds a fixed amount to principal every month. Interest falls faster because principal falls every month.
Do this in simulator: Set Extra Monthly to your chosen amount, keep other extra levers at 0, and Biweekly Off.
Best for: Stable monthly surplus income.
Annual Lump Sum
Applies one extra principal payment once per year (bonus, tax return, side-hustle profits).
Do this in simulator: Set Annual Lump Sum to your chosen amount, keep other extra levers at 0, and Biweekly Off.
Best for: Income that arrives in bigger yearly chunks.
Biweekly Rhythm
Simulates paying half every 2 weeks, creating roughly 13 monthly payments each year.
Do this in simulator: Turn Biweekly = On, keep all extra amount fields at 0.
Best for: Biweekly salary cycles and disciplined automation.
Yearly Position Buy
Increases monthly payment by a percent each year. Starts light and becomes stronger as income grows.
Do this in simulator: Set Yearly Position Buy to your chosen percent, keep Extra Monthly and Annual Lump Sum at 0 for pure test.
Best for: Salaried users expecting regular raises.
One-Time Principal Hit
Applies one large principal payment in a chosen year. This can cut future interest quickly if done early.
Do this in simulator: Set One-time Year and One-time Amount to your chosen values. Keep other extra levers at 0 for pure test.
Best for: Asset sale, inheritance, or one-time windfall.
Balanced Combo
Combines monthly extra + annual lump sum + optional biweekly acceleration without aggressive growth.
Do this in simulator: Use your Extra Monthly and Annual Lump Sum values together, turn Biweekly On, and keep growth and one-time fields at 0.
Best for: Users wanting strong impact with controlled risk.
Growth Combo
Adds monthly extra and annual lump sum, then scales payment upward yearly.
Do this in simulator: Use your Extra Monthly + Annual Lump Sum + Yearly Position Buy values together, typically with Biweekly Off.
Best for: Long-term planners with rising cash flow.
Aggressive Snowball
High-intensity combo: larger monthly extra, larger annual lump sum, yearly growth, biweekly acceleration, and optional one-time hit.
Do this in simulator: Increase your current extra values (for example about 2x monthly and 1.5x annual), add yearly growth, enable Biweekly, and optionally set one-time payment.
Best for: Very strong cash flow and highest urgency to finish early.
Biweekly + Annual
Uses biweekly acceleration plus yearly lump sum. Good compromise if monthly budgeting is tight.
Do this in simulator: Turn Biweekly On and keep your Annual Lump Sum value active. Keep other extra levers at 0 for pure test.
Best for: People who prefer paycheck rhythm and annual bonus strategy.
Conservative Start
Lower-intensity version of extra payments to reduce stress while still making progress.
Do this in simulator: Use a reduced version of your current levers (about half monthly and annual values, and slightly lower yearly growth), with Biweekly Off.
Best for: Uncertain income periods and cautious ramp-up.
Custom Selected Combo
You choose which levers are active, so this can mimic your real life budget constraints.
Do this in simulator: Turn on only the levers you can sustain and use your own entered values for those levers.
Best for: Personalized planning.
