Should I pay my mortgage off early?

Paying extra on your mortgage frees you sooner — but only if your cash flow can carry the bigger payment every month. Model the extra payment in Recurna Flow and watch what it does to your balance before you commit.

Paying down a mortgage faster is one of the most satisfying financial moves there is. It is also one of the easiest to overcommit to. An extra $300 a month sounds manageable in a calm month — the test is whether it still works in the month your insurance renews and your car needs tires.

Recurna Flow does not compute the interest you would save; your lender’s amortization schedule does that. What Flow shows you is the part the lender’s calculator hides: what the bigger payment does to your balance, week by week, for a full year. That is the number that decides whether the plan is sustainable.

How to think about it

Sustainability beats speed. A payment you can keep up for years matters more than the most aggressive one you can manage for three months. The right extra is the one your forecast carries comfortably through its lowest week.
Extra payments are a recurring commitment, not a one-off. Rounding up your payment every month is a standing drain on your balance. Treat it like any other recurring bill and see it stacked against the rest.
Keep a buffer. Money sent to the mortgage is hard to get back. If the extra payment pulls your trough close to zero, you have traded flexibility for speed — see whether that trade still leaves you a cushion.

Model it in Flow

You will test the extra payment as an adjustment in the what-if sandbox. Nothing here changes your real data.

Open the Forecast page, set the account scope to the account the mortgage comes out of, and set the date range to Next 1Y.
Open the simulation panel. The sidebar slides in and the URL gains ?sim=1.
Tap + to open the Add adjustment sheet.
If your mortgage payment is already a recurring transaction, pick the Modify type pill and select it, then raise the amount by the extra you are considering. If it is not yet tracked, pick New Recurring and add the extra as its own monthly payment described as Mortgage — extra.
Tap Add. The forecast redraws with the higher monthly outflow.

Read the forecast

Find the lowest week in the week-by-week breakdown. That trough tells you whether the extra payment is sustainable across the whole year — not just in an average month.

To weigh a few extra amounts against each other:

Build the first option (say, $200 extra), then Save the simulation as Mortgage — +$200.
Change the amount to a second option ($400 extra), or build it as a second saved simulation.
Tap Compare and select Baseline (no changes) to see the effect against your current path, or select your other saved simulation to put two amounts side by side. The chart shows the week-by-week balance delta between them.

Now you can see exactly how much each extra payment lowers your running balance. Pick the largest extra that still keeps your trough above your comfort buffer — that is the fastest payoff your cash flow can actually sustain.

Saving simulations and comparing them side by side are Pro features. On the free tier you can still build the scenario and read the effect on your 12-week forecast.

Exit simulation mode and your real forecast returns untouched. The extra payment is yours to start whenever the numbers look right.
